Nervus axillaris

	l
TA	A14.2.03.059
function	motorically innervates deltoid muscle, teres minor, sensitively innervates the shoulder joint, the skin in the area of the deltoid muscle and the lateral side of the arm.
branches	rr. musculares, rr. articulares, n. cutaneus brachii lat. sup.

Nervus axillaris (axillary nerve) represents one of the branches of the fasciculus posterior brachial plexus.

Range: C5–C6
Course of the nerve: foramen humerotripicitale → collum chirurgicum humeri → back side of the humerus → lower surface of the deltoid muscle.
Motor innervation: deltoid muscle, teres minor.
Sensory innervation: shoulder joint, skin in the area of the deltoid muscle and lateral sides of the arm.
Branches:
- rr. musculares: muscular branches for the above muscles;
- rr. articulares: for the shoulder joint;
- n. cutaneus brachii lateralis superior: sensitive nerve (see sensitive nerve innervation).
