The Axilla Region. The axilla is the name given to an area that lies underneath the glenohumeral joint, at the junction of the upper limb and the thorax. It is a passageway by which neurovascular and muscular structures can enter and leave the upper limb.
Like other flexion surfaces of large joints (groin, popliteal fossa, cubital fossa and essentially the anterior part of the neck), it is an area where blood vessels and nerves pass relatively superficially, and with an increased amount of lymph nodes.
The cervico-axillary canal is bounded by the first rib, clavicle, and superior edge of the scapula. The base of the axilla is formed by skin, subcutaneous tissue, and axillary fascia, and forms what is called the axillary fossa, or what we know as the armpit.
The axillary fossa, or the armpit, is the region of concave skin bounded by the anterior and posterior axillary folds.
The axilla is an anatomical region under the shoulder joint where the arm connects to the shoulder. It contains a variety of neurovascular structures, including the axillary artery, axillary vein, brachial plexus, and lymph nodes.
The axillary nerve runs in close proximity to the shoulder joint and around the surgical neck of the humerus, and so it can be damaged in the dislocation or with attempted reduction. Injury to the axillary nerve causes paralysis of the deltoid, and loss of sensation over regimental badge area.
The axillary region (also known as the arm pit) is a pyramid-shaped area located between the shoulder girdle and thorax. It serves as a space for neurovascular and lymphatic structures to travel through to reach the upper extremity from the neck [1] .
The glenohumeral, or shoulder, joint is a synovial joint that attaches the upper limb to the axial skeleton. It is a ball-and-socket joint, formed between the glenoid fossa of scapula (gleno-) and the head of humerus (-humeral).
glenohumeral joint. (i.e., shoulder joint. ) is one of the most flexible joints in the body and relies on a complex system of muscles, including the. rotator cuff. , to keep it in shape and enable mobility. Branches of the subclavian and. axillary arteries. supply the entire upper extremity.
Axillary fascia. The axillary fascia is relatively dense, especially in the central third of the shoulder and below the deltoid muscle. It divides at the lateral margin of the latissimus dorsi muscle into two layers, which ensheaths the muscle and are attached posteriorly to the spinous processes of the thoracic vertebrae.
