Nerve problems around the shoulder are rare, but the most commonly affected of these nerves are: 1  Axillary Nerve - supplies the Deltoid muscle. Most commonly stretched with shoulder dislocations. 2  Long Thoracic Nerve - supplies Serratus Anterior muscle and can cause Winging of the Shoulder.
The main nerves that travel into the arm run through the axilla under the shoulder. Three main nerves begin together at the shoulder: the radial nerve, the ulnar nerve, and the median nerve. These nerves carry the signals from the brain to the muscles that move the arm. The nerves also carry signals back to the brain about sensations such as touch, pain, and temperature.
In the Axilla. The axillary artery passes through the axilla, just underneath the pectoralis minor muscle, enclosed in the axillary sheath. At the level of the humeral surgical neck, the posterior and anterior circumflex humeral arteries arise. They circle posteriorly around the humerus to supply the shoulder region.
