[Rare variants of formation of human brachial nerves and arteries].
In the course of preparing muscular and neurovascular specimen of human right arm a combination of several rare anatomic variants was discovered which, to the authors opinion, are worth attention. 1. Formation of the median nerve at the border between middle and inferior thirds of brachium. 2. Variant of n. musculocutaneus origination from the lateral fascicle of plexus brachialis by several branches. 3. Variant of n. antebrachii cutaneous lateralis origination from the lateral fascicle by two branches. 4. Radial artery branching from humeral artery at the level of middle third of the brachium. 5. Three heads were discovered in m. biceps brachii. The variants described are interesting from scientific and clinical interest: they contribute to general conception of human anatomy and clinical manifestations of injuries of brachial nerves and arteries.
