New Findings What is the central question of this study? How long can humans sustain motor unit discharge during a voluntary contraction? What is the main finding and its importance? Human motor units can discharge action potentials for a longer time during a voluntary contraction than can be achieved by intracellular or extracellular current injec...

The purpose of the study was to compare the discharge characteristics of biceps brachii motor units of young and old adults when they performed steady, submaximal contractions while the arm supported different inertial loads. Young (28 ± 4 yr; n = 16) and old adults (75 ± 4 yr; n = 14) performed steady contractions with the elbow flexors at target...

The purpose of this study was to compare the discharge characteristics of motor units recruited during an isometric contraction that was sustained with the elbow flexor muscles by older adults at target forces that were less than the recruitment threshold force of each isolated motor unit. The discharge times of 27 single motor units were recorded...

The discharge of single motor units (n = 34) in the first dorsal interosseus muscle and the fluctuations in force during steady contractions were measured across a range of index finger abduction forces in old adults (77.1 +/- 6.9 yr, n = 20). These results were compared with previously reported data on 38 motor units from young adults (25.7 +/- 5....

The goal of this study was to improve the ability of a motor unit model to predict experimentally measured force variability across a wide range of forces. Motor unit discharge characteristics were obtained from 38 motor units of the first dorsal interosseus muscle. Motor unit discharges were recorded in separate isometric contractions that ranged...

Purpose Teaching can enhance the teacher’s learning through retrieval practice, elaboration, and metacognitive engagement. In anatomy education, near-peer teaching roles such as laboratory teaching assistants (TAs) may therefore benefit not only learners but also the instructors. This study investigated whether serving as an anatomy TA is associate...

Anatomy with human dissection may help to develop respect for the human body and professionalism; however, dissection may worsen students' attitudes about body weight and adiposity. The purpose of this study was to measure weight bias among Doctor of Physical Therapy (DPT) students enrolled in gross anatomy and determine if, and how the experience...

DOI: 10.1002/ase.2344 Introduction & Objective - Knowledge of pelvic anatomy is exceedingly important in gynecologic surgery, yet recent surveys have shown that gross anatomy education is typically not included in residency programs. Including donor-based anatomy education after medical school has been shown to improves surgical skills and anatomy...

Background Emergency cricothyrotomy training for non-surgeons is important as rare “cannot intubate or oxygenate events” may occur multiple times in a provider’s career when surgical expertise is not immediately available. However, such training is highly variable and often infrequent, therefore, enhancing these experiences is important. Research...

Background Preclinical medical learners are embedded in technology-rich environments, allowing them rapid access to a large volume of information. The anatomy laboratory is an environment in which faculty can assess the development of professional skills such as information literacy in preclinical medical learners. In the anatomy laboratory, many s...

Anatomical knowledge is the foundation of the educational curricula in most healthcare programs. The varying scopes of practice between healthcare professions require anatomy educators to determine what content is essential to cover in a finite time with learners. When possible, the anatomy educator bases this decision on clinical experiences; this...

Biomedical educators have turned to technologies, like social media, to supplement progressive reductions in time spent in class. Many studies of social media have been limited to quantifying learner satisfaction and studies on the effects on learning outcomes are sparse. The purpose of this study was to examine the effects of using Snapchat on lea...

The video "Emergent Cricothyrotomy Training for Non-Surgeons" reviews two distinct techniques for performing an emergency cricothyrotomy as taught by an otolaryngology surgeon utilizing cadaveric donors. The first method is employable in almost any emergency setting and uses a scalpel, a bougie, and a 6.0 endotracheal tube. The second method uses a...

Anatomical knowledge is requisite for effective physical therapy (PT) practice. Cadaver dissection is a popular teaching method employed in PT anatomy courses. Limited time in the laboratory requires effective dissection instructions. Several limitations of a printed, non-discipline specific dissection guide have been identified by students and ins...

Social media has been established as an effective method of rapidly disseminating information to a large audience and is appealing to anatomy educators that are looking for ways to provide review opportunities beyond lectures. Snapchat is unique in the social media landscape due to the ephemeral nature of the content posted, which disappears after...

Personal computer use for educational purposes by the healthcare professions students has become ubiquitous. Although the effect of computer‐based dissection instructions has been studied, there is a paucity of information regarding student browsing habits of information available on the Internet. Although current students have favorable attitudes...

This poster explores how anatomists use social media and their opinions on cadaveric images being posted on social media.

Objective: The purpose of this study was to investigate the utilization and perception of live blogged sessions of a physical therapy (PT) conference. Methods: Sessions at an international PT conference were covered in real time using a live-blogging platform. Session coverage could be viewed remotely using computers and mobile devices. Viewers cou...

Incidence rates of a third head of biceps brachii muscle have been shown to vary based on race, sex, and side of the body. Traditionally, males were thought to have higher incidences than females, and the right limb was thought to most frequently contain an additional head of biceps brachii. Additionally, innervation of this third head has been unc...

Background: Wiki platform use has potential to improve student learning by improving engagement with course material. A student-created wiki was established to serve as a repository of study tools for students in a medical school curriculum. There is a scarcity of information describing student-led creation of wikis in medical education. Objectiv...

We made a dissection guide in Apple iBooks Author that had content and delivery improvements on the traditional paper based dissection guide.

Although numerous online resources for gross anatomy are available, most feature two-dimensional photographs generated by traditional cameras. To determine whether the incorporation of light field photographs (images with an adjustable focal point) into an online anatomy resource would result in improved learning beyond traditional photographs, two...

Although numerous online resources for gross anatomy are available, most feature two-dimensional photographs generated by traditional digital cameras. Demonstrating the complex, three-dimensional relations of anatomical structures in 2D images is challenging and difficult for students to understand. To that end, we developed two online learning mod...

Background / Purpose: Two variables are known to influence the discharge characteristics of human motor units; the age of the individual and the compliance of the load supported by the limb. The purpose of this study was to compare the influence of load compliance on the discharge characteristics of biceps brachii motor unit at recruitment in you...

Age-related differences in force steadiness have been extensively examined and used as an index of motor function. However, the functional relevance of steadiness remains unclear. The aim here was to evaluate the relations among hand strength, steadiness, and function across the adult life span. Seventy-five adults (45 women; 18-89 yr) performed th...

Background / Purpose: This study was motivated by a previous result that in young adults, the discharge pattern of biceps brachii motor units at recruitment depended on the force level sustained during the task.As there are many age-related changes in the synaptic inputs and intrinsic properties of motor neurons, we hypothesized that motor unit a...

INTRODUCTION As older adults are usually weaker [1, 3, 4] and less steady than young adults [1, 2, 5], measures of strength and steadiness are frequently used as indi-ces of motor function. However, there are relatively few studies about the associations between these indices and performance on functional hand tests. The aim of the study was to eva...
