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).
- Nerve injury: in Dislocation of Shoulder Joint; fractures of the collum chirurgicum humeri (the patient is unable to perform external rotation and abduction of the arm to the horizontal).
