What is the axillary region area?
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.
Where is the axillary vein located?
Location. The axillary vein arises at the lower border of the axilla, just beneath the teres major shoulder muscle, near where the underarm meets the body.
Is the axillary a vein or artery?
In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.
What is the right axillary region?
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.
Where does the axillary vein end?
The axillary vein terminates by becoming continuous with the subclavian vein at the lateral border of the first rib 2.
What are parts of axillary artery?
It has three branches that are variable in their order: the subscapular trunk, the anterior humeral circumflex artery, and the posterior humeral circumflex artery. The subscapular trunk is typically the largest branch of the axillary artery.
What is in the axillary sheath?
The axillary sheath is a fibrous sheath that encloses the axillary artery and the three cords of the brachial plexus to form the neurovascular bundle. It is surrounded by the axillary fat. It is an extension of the prevertebral fascia of the deep cervical fascia.
Is axillary vein deep or superficial?
Deep veins — The deep veins of the upper extremity include the paired ulnar, radial, and interosseous veins in the forearm; paired brachial veins of the upper arm; and axillary vein.
Where does the axillary nerve supply?
The axillary nerve supplies three muscles in the arm: deltoid (a muscle of the shoulder), triceps (long head) and teres minor (one of the rotator cuff muscles). The axillary nerve also carries sensory information from the shoulder joint.
