Axillary Nerve Anatomy

Supplies the anterior deltoid muscle. Anaesthesia or loss in sensation of the area of the skin posterior to the deltoid muscle.

Axillary Nerve Injury Physiopedia

Paralysis of the deltoid and teres minor muscles.

Axillary nerve anatomy. Posterior terminal branch provides motor innervation to the posterior aspect. The axillary nerve is a major peripheral nerve of the upper limb that originates from the brachial plexus. Anterior terminal branch winds around the surgical neck of the humerus.

Weakness of arm abduction. It terminates by dividing into anterior and posterior divisions. Wraps around the surgical neck of the humerus running in the deep deltoid fascia with the posterior circumflex humeral artery.

Divides into anterior and posterior branches within the quadrangular space. The axillary nerve which is also called the circumflex nerve emerges from the posterior cord of a network of nerves called the brachial plexus right at the level of the armpit. Structure the anterior branch upper branch winds around the surgical neck of the humerus.

The axillary nerve then passes medially to the surgical neck of the humerus where it divides into three terminal branches. The posterior branch lower branch supplies the teres minor and the posterior part of the deltoid. The motor branch of the long head of the triceps brachii arises on average.

It emerges from the posterior cord of the brachial plexus. It then runs backwards in close relation to the capsule of shoulder joint. Wasting of the deltoid muscle.

Mixed sensory and motor nerve. Axillary nerve arises in the axilla from posterior cord of brachial plexus behind the third part of axillary artery. The trunk of the.

Enters and passes backwards through the quadrangular space. Posterior circumflex humeral artery. Injury to the axillary nerve can result in the following.

Its a major peripheral nerve of the arm carrying fibers from the fifth and sixth cervical vertebrae c5 and c6 which are in near the base of the neck.
