The nerve lies at first behind the axillary artery, [4] and in front of the subscapularis, [1] and passes downward to the lower border of that muscle.. It then winds from anterior to posterior around the neck of the humerus, in company with the posterior humeral circumflex artery, [2] through the quadrangular space (bounded above by the teres minor, below by the teres major, medially by the ...
The lower posterior boundary is called the posterior axillary fold and this is a compound structure consisting of the latissimus dorsi and teres major muscles. [8] It can descend after weight loss. [9] The anterior boundary is called the anterior axillary fold and this is rounded in shape and formed by the lower border of the pectoralis major.
The quadrangular space is a clinically important anatomic space in the arm as it provides the anterior regions of the axilla a passageway to the posterior regions. In the quadrangular space, the axillary nerve and the posterior humeral circumflex artery can be compressed or damaged due to space-occupying lesions or disruption in the anatomy due to trauma.
Inferior lateral cutaneous nerve of arm - Near blue "axillary" area, but actually branches from radial nerve. Most modern sources distinguish the superior and inferior, but some still include a single "lateral brachial cutaneous nerve". ) Intercostobrachial nerve (brown) Medial cutaneous nerve of arm (yellow) - labeled as "medial brachial ...
The deltoid is innervated by the axillary nerve. [7] The axillary nerve originates from the anterior rami of the cervical nerves C5 and C6, via the superior trunk, posterior division of the superior trunk, and the posterior cord of the brachial plexus. [8] Deltoid Muscle Labelled
The ulnar nerve innervates the muscles of the forearm and hand not innervated by the median nerve. The axillary nerve innervates the deltoid and teres minor. The radial nerve innervates the posterior muscles of the arm and forearm; Collateral branches of the brachial plexus: [13] The dorsal scapular nerve innervates rhomboid major, minor and ...
Phrenic nerve; Phrenic plexus; Posterior auricular nerve; Posterior branch of spinal nerve; Posterior cord; Posterior cutaneous nerve of arm; Posterior cutaneous nerve of forearm; Posterior cutaneous nerve of thigh; Posterior scrotal nerves; Posterior superior alveolar nerve; Proper palmar digital nerves of median nerve; Prostatic plexus (nervous)
The superior lateral cutaneous nerve of arm (or superior lateral brachial cutaneous nerve) is the continuation of the posterior branch of the axillary nerve, after it pierces the deep fascia. It contains axons from C5-C6 ventral rami.
