The reconstructive surgeries utilize pes anserinus (PA) tendons, because of their lesser post-operative clinical deficits and donor site morbidity. These surgeries require anatomical knowledge about the extent of PA formation. The goal of this study was to determine the length and width of the PA formation. The objectives were to measure the distan...

We report a rare morphological variant of the left coronary artery in this case of a female embalmed cadaver, where in the heart was nourished by double anterior and posterior interventricular arteries. These were branches of the left coronary artery and it was also observed that distribution of right coronary artery was very limited. The deceased...

Aim: The aim was to study topography and variability in the origin of anterior interosseous nerve. The objectives were to study the branching pattern of the anterior interosseous nerve supplying the flexor digitorum profundus, flexor pollicis longus, and pronator quadratus muscles. Material and methods: The present study included 70 formalin-fix...

We report a case of undivided retromandibular vein (RV) that was associated with the absence of external jugular vein (EJV). This variation in the jugular venous system was observed on the right side of the neck of a male cadaver. The posterior auricular vein drained into the RV, which joined the facial vein resulting in a common trunk. This common...

The purpose of this study was to determine the length of the semitendinosus muscle belly and its tendon in South Indian population and to study the topography and diameter of its neurovascular pedicles. The study included 46 formalin fixed human cadaveric lower limbs. The length of the semitendinosus muscle belly and its tendon were measured. The n...

Familiarity with the shape and dimensions of sella turcica is important to recognize and manage pathological conditions of pituitary gland as well as for orthodontic treatment planning. The present study aims to describe the morphology and dimensions of sella turcica from Indian population, using lateral cephalograms to set a reference data for com...

The objective of the present study was to investigate the number of the spinal nerve rootlets and to determine the length of the spinal segments in the lumbosacral region of the spinal cord. Meticulous dissection was performed to expose the nerve rootlets. The nerve rootlets were macroscopically counted in the lumbosacral region and also communicat...

Sciatic nerve is vulnerable to iatrogenic injuries during intramuscular injections in the gluteal region because of its course and relations in the gluteal region. It originates from sacral plexus, usually in the pelvic cavity and enters the gluteal region through the greater sciatic foramen below the piriformis. The level of its termination by div...

The objective of this study was to study the morphometry of the styloid process of temporal bone and prevalence of elongated styloid process. The morphology of elongated styloid process along with its embryological and clinical importance are discussed. The present study included 110 human dry skulls which were procured from the bone collections of...

Purpose: Ethmoidal foramina on the medial orbital wall show a higher incidence of variation. Surgeons performing endonasal, anterior cranial fossa and medial orbital wall surgeries must be aware of these variations as they are a source of hemorrhage and also serve as landmark in proximity to the orbital apex. Aim: The present study aims to descr...

Methylphenidate (MPH) is commonly prescribed drug for attention deficit hyperactivity disorder (ADHD) in children and these symptoms known to persist during adolescence and adulthood. The neural consequences like emotionality, anxiety like behavior and even addictive behavior in adolescence and adulthood after early-life exposure to MPH is not adeq...

The identification of mastoidal emissary veins is of importance in the neurosurgical practice to diagnose abnormal and normal structures. In the present study, the objectives were to estimate the prevalence rate of mastoidal emissary foramina in the temporal bones of the adult skull and to study their number and morphology. The present study includ...

Purpose: The objectives were to study the morphometry of occipital condyles and to find the incidence of third occipital condyle in Indian skulls. Materials and methods: In the present study, 140 occipital condyles from 70 dry skulls were analysed. The length, width, height of occipital condyles, the anterior and posterior intercondylar distance...

Vascular variations should be considered seriously, since the majority of these are incidental findings during surgeries or catheterization. A prior knowledge of the possible existence of variations in the veins, especially in the vena cava, is necessary for surgeons, radiologists, or anaesthesiologists, since central catheterization procedures hav...

Knowledge of variations in the formation of superficial palmar arch is beneficial for successful vascular surgery in the hand as well as for plastic surgeons. The authors describe an unusual completion of superficial palmar arch by first dorsal metacarpal branch of radial artery at the first interdigital cleft which was encountered during routine u...

Among the branches of common peroneal nerve, the superficial peroneal provides cutaneous innervation to major part of the dorsum of the foot and deep peroneal nerve supplies the skin over the first interdigital cleft region. The present rare case was observed during routine dissection of leg for undergraduate students, in a 52-year-old male, formal...

Objectives: Knowledge of the shape and dimensions of the glenoid are important in the design and fitting of glenoid components for total shoulder arthroplasty. An understanding of variations in normal anatomy of the glenoid is essential while evaluating pathological conditions like osseous Bankart lesions and osteochondral defects. Methods: This st...

The objectives were to find the incidence and topography of the occipital emissary foramina in skulls of South Indian Region. MATERIAL and In the present study, 78 dried adult human skulls were examined. They were analyzed for the gross incidence and position of the occipital emissary foramen. The observations were made in the squamous part of the...

Discoid lateral meniscus is a rare condition that unilateral is more common than bilateral, here we report a case of bilateral discoid lateral meniscus which was observed in the knee joints of a female fetal cadaver of 14 weeks gestation (92 mm crown-rump length). It was an incomplete type of discoid meniscus, occupying about three fourth of the ti...

Abductor pollicis longus is known for its variations in the form of multiple tendons at its insertion. The present case reports about a variation in the origin of abductor pollicis longus (APL) which has not been cited in the medical literature until date. It has been shown that the intersection area where the APL and extensor pollicis brevis cross...

Variations in the branching pattern of the external carotid artery (ECA) are well known and documented. The variation in the present case was compared with those reported before. An anomalous unilateral variation in the branching pattern of the left ECA was observed in a male embalmed cadaver. In this case, the ECA gives a direct branch directly to...

A variation in the branching of the coeliac trunk was found in which the coeliac trunk gave four arteries, the common hepatic, splenic, left gastric and an additional dorsal pancreatic artery. One of the branches of the dorsal pancreatic artery joined with the right gastroepiploic artery close to its origin to form Kirk's arcade. The clinical impli...

During the laboratory dissection of the fore arm, an accessory head of flexor pollicis longus muscle has been observed unilaterally in the right upper limb of a male cadaver. It took its origin from the under surface of flexor digitorum superficialis muscle just distal to the origin of this muscle from medial epicondyle. On further dissection we ha...
