Bilateral variations in the branching pattern of brachial artery
Introduction The recognition and documentation of developmental variation in the course, distribution, and branching pattern of the arteries of upper limb is highly significant in the angiographic and surgical practice. The frequent existence of upper limb vascular variations is attributed to the complex and multiple sites of their embryonic development [1–3]. Variations of the upper limb arter...
متن کاملBilateral absence of musculocutaneous nerve with unusual branching pattern of lateral cord and median nerve of brachial plexus
A 43-year-old female cadaver showed a complete bilateral absence of the musculocutaneous nerve. The anterior compartment muscles of both arms were supplied by median nerve excepting the coracobrachialis which was innervated by a direct branch from the lateral cord of brachial plexus. The median nerve, after supplying the biceps and brachialis muscles, gave onto the lateral cutaneous nerve of th...
متن کاملMultiple variations in the course and motor branching pattern of the musculocutaneous nerve with unusual communication with the median nerve.
Anatomic variations in course and motor branching pattern of the musculocutaneous nerve (MCN) with unusual communication with the median nerve were determined on the left arm of a 62-year-old formalin fixed male cadaver. The MCN did not pierce the coracobrachialis muscle. It provided 4 primary motor branches. The first branch emerged 1.5 cm inferior to the coracoid process to innervate the cora...

Variations associated with high division of the superficial brachial artery
Introduction Several investigators reported variations in the arterial pattern of upper limb [1–2]. Most of these variations hypothesized by the failure of regression of some paths of embryonic arterial trunks [2]. The presence of superficial brachial artery (SBA) and the usual pattern of its branching in the upper arm or forearm have also been reported with prevalence rate varying from 0.2–25%...
