Axillary nerve C5 and C6, a branch of the posterior chord of the brachial plexus
The deltoid is innervated by the axillary nerve which originates from the ventral rami of the C5 and C6 spinal nerves, via the superior trunk, posterior division of the superior trunk, and the posterior cord of the brachial plexus.

The axillary nerve innervates the deltoid and teres minor muscles in the shoulder. It is responsible for providing motor function to these muscles, allowing for shoulder movement and stability. Additionally, the axillary nerve provides sensory information to the skin over the shoulder.
the spinal nerve sends nerve impulses away from the CNS

starting in the spinal cord, trace a motor pathway to the adductor muscles of the thigh. Include the spinal cord root, spinal nerve, nerve plexus, and specific peripheral nerve involved in the pathway
All nerves forming the brachial plexus are vulerable to injuries. Most commonly affected are axillary nerve, suprascapular nerve and the radial nerve. The axillary nerve is injured in 37% making it the most commonly injured structure with this type of injury.Suprascapular nerve at 29%, and the radial nerve (22%).
