Anatomy

Upper Limb

Question 211 of 239

Your consultant is telling you about a recent patient he saw. The patient had dislocated their shoulder during a tonic-clonic seizure and sustained an axillary nerve injury as a result. The consultant tells you that after reducing the dislocation the patient was unable to perform certain movements. The axillary nerve innervates which of the following muscles:

Answer:

The axillary nerve innervates the deltoid muscle and the teres minor. It gives rise to the superior lateral cutaneous nerve of the arm which supplies the regimental badge area on the lateral arm.

Table: Anatomical Overview of the Axillary Nerve

Nerve Axillary
Nerve roots C5 and C6
Plexus cords Posterior cord
Motor Supply Deltoid, teres minor
Sensory supply Regimental badge area on lateral arm via superior lateral cutaneous nerve of the arm

The axillary nerve arises from the posterior cord containing fibres from nerve roots C5 and C6.

The axillary nerve and associated blood vessels (the posterior circumflex humeral artery and vein) enter the deltoid by passing posteriorly around the surgical neck of the humerus (where it is vulnerable to damage).

The axillary nerve innervates the teres minor and deltoid muscles and the skin over the inferior portion of the deltoid, the 'regimental badge area' (via the superior lateral cutaneous nerve of the arm).
