Its fibers originate from the C5 and C6 roots and travel through the upper trunk to the posterior cord. The nerve has a very short path. At this point, the axillary nerve gives branches to the teres minor muscle and then it curves around the neck of the humerus, under the deltoid muscle..
Subsequently, one may also ask, what does the axillary nerve do?
Function. The axillary nerve has both a motor and a sensory distribution of innervation. It has motor fibres that innervate the deltoid muscle, acting as an abductor, flexor and extensor at the shoulder joint, as well as the teres minor muscle, allowing lateral rotation of the glenohumeral joint.
Furthermore, where is the axillary nerve prone to injury? The axillary nerve is susceptible to injury at several sites, including the origin of the nerve from the posterior cord, the anterior inferior aspect of the subscapularis muscle and shoulder capsule, the quadrilateral space, and within the subfascial surface of the deltoid muscle.
Also Know, what happens if axillary nerve is damaged?
Axillary nerve palsy is a neurological condition in which the axillary (also called circumflex) nerve has been damaged by shoulder dislocation. It can cause weak deltoid and sensory loss below the shoulder. Since this is a problem with just one nerve, it is a type of Peripheral neuropathy called mononeuropathy.
What nerve controls the deltoid muscle?
