Branches of the three parts of the axillary artery anastomose with each other and with those of the subclavian and brachial artery around the scapula as depicted in the image below. The plexus is formed by the anterior rami (divisions) of cervical spinal nerves C1-C4. (A) Cross-sectional anatomy of the axillary fossa and ultrasound image (B) of the terminal nerves of brachial plexus. The brachial plexus is a network of nerves that is responsible for sending signals from the spinal cord to the shoulder, arm, and hand, and an injury to this bundle of nerves can be very serious, especially if they are ripped away or The axillary nerve is formed from the C5 and C6 nerve roots of the brachial plexus. Also known as Circumflex nerve. When the axillary nerve splits off from the posterior cord, the continuation of the cord is the radial nerve. This branch enters the muscle at an average of only 5 cm directly inferior to the posterolateral corner of the acromion. 5 + 9 = ? courses on the posterior wall of the axilla (on subscapularis, latissimus dorsi, teres major) 3 Branches in axilla.

It performs abduction of the upper limb at the glenohumeral joint and is innervated by the anterior terminal branch of the axillary nerve. The long thoracic nerve should be preserved; it runs medial to the thoracodorsal bundle and is identified close to the chest wall posteriorly. superficial branch radial nerve; dorsal digital branch; Origin: Radial nerve originates from the posterior cord of the brachial plexus (C5-T1) behind axillary artery; Course: Posterior wall axilla. Branches from the posterior intercostal artery arising from the subclavian artery and thoracic aorta also takes part in the anastomoses. The PCHA then courses anteriorly around the surgical neck of the humerus, supplying the shoulder joint and the deltoid muscle and anastomosing with the ACHA and profunda brachii. Object Grafting or nerve transfers to the axillary nerve have been performed using a deltopectoral approach and/or a posterior arm approach. The axillary block aims to block the terminal branches of the brachial plexus which include the median, ulnar, radial and musculocutaneous nerves.
