A rare case of additional slip in the origin of the clavicular head of sternocleidomastoid muscle was found during our routine dissection, on both sides of the neck in an elderly male cadaver. However, on both side of the same muscle no such additional slip of origin was found at the sternal head of the sternocleidomastoid near its origin nor at its insertion of the muscle.
SUMMARY:The increasing use of invasive diagnostic and interventional procedures in cardiovascular diseases makes it important that the type and frequency of vascular variations are well documented and understood. Sound knowledge of neurovascular variations is important for surgeons who remove axillary lymph nodes, to anesthesiologists, and orthopedic surgeons, considering the frequency of procedures done in this region. An unusual variation in the branching pattern of axillary artery was observed on the left side of a 60 year old female cadaver. In the present case the course and distribution of the first and second part of the axillary artery were normal. But a rare case of unusual origin of subscapular, anterior and posterior circumflex humeral, profunda brachii artery and ulnar collateral arteries from a common trunk were found on the left side during routine dissection. This common trunk was found arising from the third part of the axillary artery and at its commencement it was found passing between the two roots of the median nerve. Cases with this kind of variations should be examined or operated carefully during surgical or electrophysiological procedures.
Silver staining of nucleolar organizing regions (NOR) is common, but a standard protocol is lacking. A modification of a rapid silver nitrate staining technique for NORs is presented here. Advantages of the modified technique include reliability, speed, cost and the fact that it can be carried out in the light.
Arches of foot is the blend of skeletal and muscular components, which is exclusive characteristic feature of evolution as an alteration to routine erect posture in humans. The human foot is convened mechanical intricacy and essential constancy due to "arches of foot". Appreciative muscle construction of the foot may assist in the intention of surgical trials such as tendon transfer, biomechanical sculpting of the foot, prosthesis strategy, and scrutiny of foot function. During routine dissection of the foot it was noted that the tendon of flexor digitorum brevis to the little toe was missing and was replaced by a musculo-tendinous slip arising from the tendon of flexor digitorum longus in the sole of the foot. Hence, the awareness of the incidence of absence and deviations of fourth slip of flexor digitorum brevis in relation to the demographic features of patients would be of clinical importance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
