What do the branches of the axillary artery supply?

What do the branches of 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 happens if the axillary artery is damaged?

Damage to the axillary artery and brachial plexus can present with a variety of neurovascular signs and symptoms—coldness, pallor, pulseless extremity, delayed or absent capillary refill and others. Impaired upper extremity function may occur with paresthesias or complete paralysis.

What are the 3 parts of the 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.

Which is true about axillary artery?

Correct answer : C. It extends from outer border of second rib to the lower border of teres minor. Axillary artery extends from outer border of first rib to the lower border of teres major. Pectoralis minor crosses the axillary artery and divides it into 3 parts.

Where is the axillary pulse?

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….

How do you prevent brachial plexus injury?

Prevention. Although damage to your brachial plexus often can’t be prevented, you can take steps to reduce the risk of complications once an injury has occurred: For yourself. If you temporarily lose the use of your hand or arm, daily range-of-motion exercises and physical therapy can help prevent joint stiffness.

Where does the axillary nerve supply?

Usually, the axillary nerve contains fibers from the C5 and C6 ventral rami. This nerve innervates the teres minor and deltoid muscles, the skin over the shoulder (upper lateral brachial nerve), and the glenohumeral joint.

Where does axillary nerve arise from?

Axillary nerve (ventral rami of C5 & C6) arises from the posterior cord of brachial plexus giving muscular branches to teres minor & deltoid. It also supplies the shoulder joint and the skin over it [1].

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.

Why do I feel electricity in my arms?

Minor damage often occurs during contact sports, such as football or wrestling, when the brachial plexus nerves get stretched or compressed. These are called stingers or burners, and can produce the following symptoms: A feeling like an electric shock or a burning sensation shooting down your arm.

What function does the axillary artery serve?

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 does axillary artery mean?

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 are the three parts of the axillary artery?

Three parts of the axillary artery are described: proximal, posterior, and distal to the pectoralis minor muscle. Branches: 1st part-superior thoracic artery; 2nd part-thoracoacromial arterial trunk, lateral thoracic artery; 3rd part-subscapular artery, anterior and posterior humeral circumflex arteries. Synonym(s): arteria axillaris [TA] .

What is the function of the axillary nerve?

Function. The axillary nerve has both a motor and a sensory distribution of innervation. It has motor fibres that innervate the deltoid muscle, acting as an abductor, flexor and extensor at the shoulder joint, as well as the teres minor muscle, allowing lateral rotation of the glenohumeral joint. As mentioned above,…
