Multiple arterial, neural and muscular variations in upper limb of a single cadaver.

During routine dissection classes to undergraduate medical students, we have observed some important anatomic variations in the right upper limb of a 45-year-old cadaver. The anomalies were superficial ulnar artery, persistent median artery, variant superficial palmar arch, third head for biceps brachii, accessory head for flexor pollicis longus, variant insertion of pectoralis major, absence of musculocutaneous nerve, coracobrachialis muscle supplied by lateral root of median nerve and anomalous branching of median nerve in arm and forearm. Although there are individual reports about these variations, the combination of these variations in one cadaver has not previously been described in the literature consulted.

Trifurcation of brachial artery with variant course of radial artery: rare observation.

Variations in the arterial pattern of the upper limb have been observed frequently, either in the routine dissections or in clinical practice. The aim of the present study was to describe the anatomical, surgical and embryological importance of major arteries of upper limbs of human beings. The present article is the report of low division and trifurcation of brachial artery and abnormal course of radial artery (passing deep to the pronator teres muscle) found in a 45-year-old embalmed male cadaver.

Unusual origin of radial collateral artery noted in quadrangular space syndrome.

In this paper, an unusual origin of the radial collateral artery of the arm is reported. The radial collateral artery in one of the cadavers dissected by us originated from the posterior circumflex humeral artery. The importance of this abnormal origin of the radial collateral artery from the posterior circumflex humeral artery in quadrangular space syndrome is discussed.
