Why is the axillary artery important?

The axillary artery is a large muscular vessel that travels through the axilla. It is responsible for carrying oxygen-rich blood to the upper limb, as well as to parts of the musculocutaneous system of the scapula and upper lateral thorax.

What muscles does the axillary artery supply?

It follows the lateral margin of the muscle to the thoracic wall and supplies the serratus anterior and pectoral muscles, axillary lymph nodes, and subscapularis. It anastomoses with the internal thoracic, subscapular, and intercostal arteries and the pectoral branch of the thoracoacromial artery.

What does the axillary artery supply blood to?

Anatomical terminology 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.

Which muscles are supplying by the scapular circumflex artery?

They contribute to the blood supply of three muscles (deltoid, teres minor, triceps brachii), glenohumeral joint and two small cutaneous areas partially overlying the scapula. This article will discuss the anatomy and function of the circumflex scapular artery (scapular circumflex artery).

What is the axillary?

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.

What muscles does the anterior humeral circumflex artery supply?

Supply. The anterior circumflex humeral artery provides part of the blood supply to the glenohumeral joint, teres major and minor, and deltoid muscles. The ascending branch provides supply to the head of the humerus 1.

What does lateral thoracic artery supply?

The lateral thoracic artery supplies the axillary lymph nodes, serratus anterior, pectoralis major, pectoralis minor and subscapularis muscles. Additionally, it can provide blood supply to the breast in females.

What does the circumflex humeral artery supply?

Is the axilla a muscle?

As usually defined, the axilla is bordered by the fascial coverings of the following muscles: the pectoralis major and pectoralis minor anteriorly; the latissimus dorsi, teres major, and subscapularis posteriorly; the chest wall and serratus anterior medially; and the coracobrachialis and biceps laterally.

Is axillary anterior or posterior?

The axillary apex is the interval between the superior border of the scapula, the posterior border of the clavicle, and the external border of the first rib. The pectoralis major and the latissimus dorsi form the major anterior and posterior folds, respectively, of the axilla.

What is the function of the humeral circumflex artery?

Where does the axillary artery supply blood to?

Axillary artery. The second part of the artery is behind the pectoralis minor muscle. The third part of the artery is lateral (to the side of, or farther away from the middle) to the pectoralis minor muscle. The three parts of the axillary artery work together to supply oxygenated blood to the thorax, upper limb, and axillary regions.

What is the difference between the axillary and upper limb?

The upper limb refers to the arm from the shoulder to the hand. The axillary artery is a continuation of the subclavian artery and begins when it crosses the first rib. As it moves downward it becomes the brachial artery.

Which arteries supply blood to the pectoralis major and minor muscles?

The pectoral arteries provide blood to the pectoralis major and minor muscles. The clavicular artery provides blood to the subclavius muscle region. The deltoid artery provides blood to the deltoid region. The second branch of the second part of the axillary artery is the lateral thoracic artery.

How is the axillary vein mobilized?

The axillary vein lies below the muscle. The vein is mobilized for a distance of approximately 5 or 6 cm. To achieve adequate mobilization, it may be necessary to ligate and divide several venous tributaries and to divide part of the pectoralis minor muscle. A fascial layer beneath the axillary vein separates the vein from the axillary artery.
