Questions related to Anatomy
I'm looking for a program that will allow me to reconstruct nerve fascicles and intraneural anatomy of the radial and axillary nerves, based on stained nerve sections. What software do you recommend in terms of ease of use, availability, reliability, etc? Thank you!
I am looking for details in CXRs pertaining to the angle of rotation, missing lung portions (like the base and apex), under/over exposure, overlying anatomy (like Chin) and other details on the data quality. Are there any publicly available Chest X-ray collections that include these metadata?
I am a hands on learner and it's hard to get the physiology in class because I can't touch it
I try to perform renal neve recording (efferent nerve and afferent renal nerve).
Please see attached 2 pictures. I performed left retroperitoneal approach. The left kidney exists at the left side of these pictures. Yellow lines show estimated nerves, and red lines show aorta and renal artery. )
I was taught to record at nerve A by my boss and actually I could record 'efferent' signal. So, this seems to the sympathetic nerve fiber. However, I couldn't record 'afferent renal nerve signal' at nerve A.
The researcher who performed 'afferent' renal nerve recording told me that he recorded at nerve B. However, nerve B is thin.In addition, lymph ducts run along renal artery. It's difficult for me to distinguish renal nerve (nerve B) from lymph ducts.
So, I have several questions:
1, What is nerve A? Is this also a renal nerve or a splanchnic nerve?
2, Which nerve should I record at, A or B?
3, What is a good method or a good clue to distinguish lymph duct from nerve?
(Does the lymph duct run along aorta?)
The potential for impacts compressing some part of the spinal dural sac to injure the spinal cord distant to the impact site through its fixation by, above all, the dent(icul)ate ligament has again and again be alerted to.

No longer capable of investigating this point, I am looking for colleagues sharing my interest in this field of research.
This is an example of the type of section I'd be analyzing. They contain hair shafts that may be detected by the software. Have any of you done analyses using QuPath on this type of sample? What settings do you use to get around this issue.
I have used Allen Mouse Brain Explorer for years and it was awesome but it no longer works on my Mac and its super depressing. Any recommendations for anatomy/ comparative anatomy atlases with advanced features or photos as apposed to illustrations ?
Many Thanks in advance
For a depot injection designed for absorption by macrophage action, which injection route would be optimal to have most drug introduced into the lung by the lymph vessel?
Hey, Could you please spare 10 minutes and watch the related video of my prototype and answer the required questions?
I really appreciate your time.
I'm doing a survey as part of an Audacious program (https://www.startupdunedin.nz/audacious), which essentially is a StartUp initiative at Otago University. I'm curious to understand what level of programming do biologists these days need during their day to day research.
For all the biologists out there here are some questions to start the discussion on this topic:
1) Have you done any programming till date? If so which language did you use and for what purpose?
2) How have to overcome programming limitations? For example, did you get the work done through bioinformaticians, or sought help from your programming friend, etc?
3) Have you used online biological databases for your research? If so, which one?
4) How much of artificial intelligence have you used in your research? Do you see AI potential in your current work?
If you have anything else to add, please feel free.
I am doing a research on virtual reality simulation for endoscopic brain surgery. I need a medically accurate 3D model of a human head. It has to include all the veins, skull, muscles, nerves and brain anatomy. This simulation will be used to train students on the surgery. Where do I buy downloadable full anatomy 3D models?
In different climate different plants can growing. To change the climate of a region slowly and gradually there I think changes occurs in the morphology, anatomy and gentics of a species. I means you are agree with me or not?

I am have gathered data across many published studies regarding the anatomy of a given anatomical structure. Ultimately, my goal is to suggest classifications (based on 3d differences in the anatomical presentation of the structure). I am just wondering if there were any suggestions regarding how to go about comparing these structures?
Happy to answer further questions and apologies if the answer here is rather obvious.
Hi everyone. I have a thin section of an epiphytic orchid root here and I have no clue what those purple blotches close to the bottom of the root are.
I'd highly appreciate it if there is anyone to guide me to a certain direction, to understand those cell structures.
Thanks in advance!
Cadaver dissection are the best adopted and accepted teaching tool in anatomy teaching from the accident time till date.
Does the dissecting room still have a place in educating our under- and postgraduate students after pandemic? As the etiopathogenesis and the outcome is not yet know.
Cadevers, dissection. post pandemic
I have problem how to differentiate atrium and ventricle in congenital heart disease in baby 2 month, with situs solitus , dextroposition, with criss cross atrioventricular
I have been trying to learn how to dissect out the genital anatomy of snails for the purposes of taxonomy but I haven't been able to find any good advice or resources on this. I am identifying some succineids (and occasionally smaller things) and the morphology of the genital system seems to be very important. Can anyone provide guidance in this area for resources that are useful?
Hi all! My work team and I are looking for papers on muscular descriptions of the hindlimbs of birds (extant and extinct) that include the intrinsic muscles of digits. Any help will be more than welcome! Thanks!
Each places has its own atmosphere (olfactory modality). For example : the olfactory perception in anatomy class is different from the olfactory perception in chemistry class. Although maybe we don't realize about that. Can delusion occur when the very intense olfactory memory has after discharge in our brain ?
Are functional maps in the cortex used by the brain to carry out computations or are they just a byproduct of wiring minimization?
A key element to answer this question is to know if, when neurons from a cortical map project their axons to the dendrite of a downstream neuron, they retain any spatial order proportional to their location in the map.
For example, in the cartoon below, the four neurons from a cortical map (in black) project their axons to a downstream neuron's dendrite (in green). The relative spatial position of the synapses (black circles) is proportional to the relative position of the neuron in the map.
I would be very grateful if you could point me to any relevant paper addressing this question, in particular in the cortex of the primate (e.g. axon tracing experiments).
I am studying bat brains through endocranial casts and I cannot identify which structure could be present in sort of a canal located dorsally to the cribriform plate. It is like olfactory nerves exit the olfactory bulbs through the punctuated cribriform plate, while another thing exit the olfactory bulbs more dorsally, going over the cribriform plate. It's really bizarre because it's like a plate of space starting at the antero-dorsal top of the olfactory bulbs, and depending on the taxa it can variate in thickness (sometimes thinner at the center of the bulbs, sometimes the reverse).
I tried to search in the literature but I didn't find anything satisfying. I eliminated the possibility that these structures may be vomeronasal nerves (they originate at the dorsal top of the accessory olfactory bulb, so rather in the middle of the main olfactory bulb ; see Fig. 6 of
Could anyone help me ? Even if you don't work on bats especially, but on other mammalian groups, any idea would be helpful.
Thanks a lot,
What do you think about the balance between exploring widely different designs vs. local optimization at different levels of biology (genomics, transcriptomics, proteomics, anatomy, etc.)? Which levels are more or less modular or plastic?
In the endocrine system, for example, one feels that having tropic hormones (i.e., those controlling the release of other signaling hormones at other glands) may offer a finer and perhaps more robust regulation, compared to a being where all hormones were non-tropic. However, the anatomic location of elements in these networks is not trivial. For example, in the renin-angiotensin-aldosterone system, renin is produced in the kidney, and aldosterone eventually exerts its effects in the kidney as well. However, the intermediate step by angiotensin-converting enzyme (ACE) mainly occurs in the lungs, which could introduce a delay in the regulation.
Do we have good explanations for the sites of production and action of different hormones in the body? Are there common principles to be learned as optimized by evolution in this respect? Or are happenstances/contingent evolution stronger determinants?
Thank you for sharing your thoughts!
There is a theory saying that emotions are controlled by the right side of the brain and logic is controlled by the other side. Is the brain really divided into two sides when it comes to controlling different aspects of human behaviour?
As we know,the pulse propagates in wave form and the velocity of wave propagation depends on the propagation medium features. So,Is it possible to use the measurment of velocity of pulse propagation in the body to diagnose cardiovascular problems such as hypertension and hypotension?
Is it obvious that VR can help medical education? Yes.
Then why are so many academic institutions resistant to implement this technology?
I would like to personally extend an offer to demonstrate hands on to any medical school interested and give a live demo opportunity to anyone in this sphere to learn about this technology.
I will travel anywhere in the world to promote this know how. It’s a rising tides float all boats equation. The VR community is in its diapers stage.
Respiratory infections can be transmitted through droplets of different sizes: when the droplet particles are >5-10 μm in diameter they are referred to as respiratory droplets, and when then are <5μm in diameter, they are referred to as droplet nuclei. According to current evidence, COVID-19 virus is primarily transmitted between people through respiratory droplets and contact routes.2-7 In an analysis of 75,465 COVID-19 cases in China, airborne transmission was not reported.
Droplet transmission occurs when a person is in in close contact (within 1 m) with someone who has respiratory symptoms (e.g., coughing or sneezing) and is therefore at risk of having his/her mucosae (mouth and nose) or conjunctiva (eyes) exposed to potentially infective respiratory droplets. Transmission may also occur through fomites in the immediate environment around the infected person. Therefore, transmission of the COVID-19 virus can occur by direct contact with infected people and indirect contact with surfaces in the immediate environment or with objects used on the infected person (e.g., stethoscope or thermometer).
Airborne transmission is different from droplet transmission as it refers to the presence of microbes within droplet nuclei, which are generally considered to be particles <5μm in diameter, can remain in the air for long periods of time and be transmitted to others over distances greater than 1 m.
In the context of COVID-19, airborne transmission may be possible in specific circumstances and settings in which procedures or support treatments that generate aerosols are performed; i.e., endotracheal intubation, bronchoscopy, open suctioning, administration of nebulized treatment, manual ventilation before intubation, turning the patient to the prone position, disconnecting the patient from the ventilator, non-invasive positive-pressure ventilation, tracheostomy, and cardiopulmonary resuscitation.
There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen. There have been no reports of faecal−oral transmission of the COVID-19 virus to date.
I would like to introduce Augmented Reality (AR) as one of the ways to learn anatomy to our students, and I have been looking at some literature in this regard. I noted from several articles that different authors developed different AR apps for their research. I have found many of these Apps to be rather complex. Kindly advise on how I, someone with no computing background, could really come up with an App which we can use for teaching/learning anatomy. In particular, I am interested in an AR App which has several pedagogical affordances including interaction among learners and one that can be deployed on a smartphone.
Probiotics are live microorganisms that are intended to have health benefits when consumed or applied to the body. They can be found in yogurt and other fermented foods, dietary supplements, and beauty products.
The virus is primarily spread between people during close contact, often via small droplets produced by coughing, sneezing, or talking. While these droplets are produced when breathing out, they usually fall to the ground or onto surfaces rather than remain in the air over long distances.People may also become infected by touching a contaminated surface and then touching their eyes, nose, or mouth. The virus can survive on surfaces for up to 72 hours. It is most contagious during the first three days after the onset of symptoms, although spread may be possible before symptoms appear and in later stages of the disease.
A hospital-acquired infection (HAI), also known as a nosocomial infection, is an infection that is acquired in a hospital or other health care facility. To emphasize both hospital and nonhospital settings, it is sometimes instead called a health care–associated infection (HAI or HCAI).
For our study, we need anatomical MRI, CT, and sonographic images of human hands in order to run statistical analysis on them. We would prefer to not need to make a database ourselves for the study, as MRI scan time can be extremely costly. For our study, optimal database image sets would:
- Regard living subjects
- Contain height data associated with each subject
- contain weight data associated with each subject
- Contain the age division of each subject
Could someone point me in the right direction?, Any and all help would be greatly appreciated. Thankyou

For a project I am working on, I need to gain an overview of the precise spatial location of nerves in pigs, starting with a literature search. My current approach to find references is based primarily on veterinary textbooks/publications, but I have not found anything that goes into enough detail to suit my purpose. I was wondering if anyone could recommend any citations that may help (anatomical/comparative studies, textbooks, etc).
Does anybody know about papers or studies regarding the inner structure and pneumatization of pterosaur vertebrae, determined via CT scanning? Taxa of interest are pterodactylidae, istiodactylidae, ornithocheiridae and basal members of azhdarchidae.

I mean sometime we have limited individuals concerned with any taxa, carrying risk to dissect or designated any type.. now a day few new techniques are available to scan even anatomy of any insect. its hopefully a best technique or methodology for future prospective if we work on this . suggestion are welcome.
On-the-ground experience would suggest that sound/noise pollution and mercury contamination may be coincidental in artisanal and small-scale gold-mining stakeholders and their bodies. If so, does any literature make explicit this coincidence or explore it further?
The phenomenon of respiratory sinus arrhythmia is well known. But, I don't know (I am an engineer) the exact receptors, feedback mechanisms, cerebral control centres, etc. involved in this process. Also, experiments have shown that varieties of controlled deep breathing (pranayama) bring down the blood pressure (I have experienced this personally also, having become free of my hypertensive medications for the past 3 years, after having been dependent on them earlier for over 9 years. I want to understand the complete physiological mechanism. I shall be grateful to anyone, who can point me to relevant books, journal papers, review papers, etc.
I took pictures of some neurons I want to reconstruct using ImageJ; however, they are not in the same x and y plane. I can built a z-stack without problems, but of course, they do not appear aligned. I was told to install these two plugins so that I can solve such problem
but now, when I import a sequence of images and try to convert them into a RGB-stack (as demanded by the plugin), I obtain instead a series of 8-bit images and can't go further.
Does anybody have experienced such problem with these plugins?, does anybody know any other plugin or method to align a z-stack in order to reconstruct cells? Is there any other software I can use to make reconstructions? Any suggestions?
there is a work on the anatomy of Abeta. researchers found that Abeta is hollow, like a tube, suggesting an object for information processing, as are MT..

In telecommunications, a transmission system is a system which transmits a signal from one place to another. The signal can be an electrical, optical or radio signal.
Can we consider some of the human body systems as transmission systems and then model it using telecommunications' concepts for better understanding?
If we do, can someone please provides some examples of these systems and determines their basic elements(message, transmitter, medium and receiver)?
