Case report: third head for the biceps brachii muscle associated with an additional insertion of coracobrachialis muscle

This case is reporting a third head for the biceps brachii muscle associated with an additional insertion for the coracobrachialis muscle. They were observed in the flexor aspect of the left arm of an adult male cadaver. Third head of the biceps brachii took origin mainly from the medial border of the shaft of the humerus and partially from the adjacent brachialis muscle. It terminated, by joining the lower common part of the muscle. It was innervated by the musculocutaneous nerve, through a branch that arises from that for the brachialis muscle. The additional insertion of the coracobrachialis muscle was by a fleshy slip, which was attached into the anteromedial surface of the shaft of the humerus. Whereas variations of this type are of interest to the gross anatomists, its functional and clinical implications cannot be undermined

Effects of passive cigarette smoking on serum lipid profile, some apolipoproteins and lecithin cholesterol acyl transferase enzyme activity in exposed children

In this study, serum concentration of total cholesterol, triglycerides, high density lipoprotein-cholesterol, low density lipoprotein cholesterol, apolipoproteins A and B as well as plasma lecithin cholesterol acyl transferase [LCAT] activity were assayed in 61 passive cigarette exposed children vs 20 non-exposed children of matched age and sex. The results provided a further evidence for a definite disturbance of lipid metabolism and reduced level of LCAT enzyme activity in the plasma of exposed children is an important contributing risk factor in lipoprotein abnormalities in those children
