Document Summary

Objective: superficial dissection of the hand; identify major structures. Indentify the palmar aponeurosis and the flexor retinaculum. Palmaris brevis muscle arises from the medial aspect of the palmar aponeurosis. Carefully remove the palmar aponeurosis; nerves and vessels lie immediately deep to it. Detach palmaris brevis from the palmar aponeurosis; reflect it medially. Ulnar nerve and ulnar artery can be followed into the palm. Identify the recurrent branch of the median nerve. This nerve is very superficial; it supplies muscles of the thenar eminence. Median nerve: also innervates the lateral 2 lumbrical muscles. Identify common palmar digital arteries arising from the superificial palmar arch. Identify and dissect proper palmar digital arteries (branches of common palmar digital arteries) Identify the superficial branch of the ulnar nerve. Cutaneous innervation to medial 1 digits, and innervates palmaris brevis muscle. The deep branch of ulnar nerve disappears as it pierces muscles of the hypothenar eminence. It reappears at the level of the deep palm.
