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.

UI	MeSH Term	Description	Entries
D001916	Brachial Artery	The continuation of the axillary artery; it branches into the radial and ulnar arteries.	Arteries, Brachial,Artery, Brachial,Brachial Arteries
D001917	Brachial Plexus	The large network of nerve fibers which distributes the innervation of the upper extremity. The brachial plexus extends from the neck into the axilla. In humans, the nerves of the plexus usually originate from the lower cervical and the first thoracic spinal cord segments (C5-C8 and T1), but variations are not uncommon.	Plexus, Brachial

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D012782	Shoulder	Part of the body in humans and primates where the arms connect to the trunk. The shoulder has five joints; ACROMIOCLAVICULAR joint, CORACOCLAVICULAR joint, GLENOHUMERAL joint, scapulathoracic joint, and STERNOCLAVICULAR joint.	Shoulders
D012867	Skin	The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
D018482	Muscle, Skeletal	A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.
