4b. The Axilla The brachial plexus thus surrounds the artery on three sides, and separates it from direct contact with the vein and adjacent muscles. The third portion of the axillary artery extends from the lower border of the Pectoralis minor to the lower border of the tendon of the Teres major.

- Please try again later. The body has about 20 to 40 bean-shaped axillary lymph nodes located in the underarm area. These lymph nodes are responsible for draining lymph – a clear or white fluid made up of white blood cells – from the breasts and surrounding areas, including the neck, the upper arms, and the underarm area.

The Axilla Region The main, and clinically important contents of the axilla region include muscles, nerves, vasculature and lymphatics: 1  Axillary artery – It is the main artery supplying the upper limb. 2  Axillary vein – The main vein draining the upper limb, its two largest tributaries are the cephalic and basilic veins.

Muscles of the Upper Arm In this article, we shall look at the anatomy of the muscles of the upper arm – their attachments, innervation and actions. There are three muscles located in the anterior compartment of the upper arm – biceps brachii, coracobrachialis and brachialis. They are all innervated by the musculocutaneous nerve. A good memory aid for this is BBC – biceps, brachialis, coracobrachialis.

Axillary artery Axillary 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.

Axillary (armpit) breast In the past, removal of axillary breast requires surgical excision which results in a fairly long scar. However we can now effectively remove breast tissue with liposuction. This results in a shorter recovery period as well as an inconspicuous scar.xillary (armpit) breast. Abnormal breast tissue can be present outside of the normal breast location. The axilla (armpit) is such an area where we can sometimes find abnormal breast tissue.

Biceps brachii The biceps brachii is a bi-articular muscle, which means that it helps control the motion of two different joints, the shoulder and the elbow. The function of the biceps at the elbow is essential to the function of the forearm in lifting. The function of the biceps brachii at the shoulder is less pronounced, playing minor roles in moving the arms forward, upward, and sideways.

The Best Bodybuilding Exercises: Brachialis Curls The brachialis is a muscle located at the front of your upper arms. It originates at the lower half of the front of the humerus, or upper arm bone, and inserts at the front of the ulna, or outer forearm bone. If you look directly at the front of your upper arms, you can't see the brachialis.

Biceps The biceps is a muscle in the upper arm with two heads, called the short head and the long head, which converge into a single mass. It is one of the three muscles in the anterior compartment of the arm, the others being the brachialis muscle and the coracobrachialis muscle, with which the biceps shares a nerve supply.

Top 30 Doctor insights on: Armpit Pain No Swelling Nonspecific sign: The armpit (axilla) has a lot going on in a small space...All the muscles, blood vessels, and nerves that connect the arm to the torso traverse this space, there are a lot of lymph nodes, plus there are many specialized skin glands. Axillary pain can be related to any of these structures.

Biceps brachii The biceps brachii, sometimes known simply as the biceps, is a skeletal muscle that is involved in the movement of the elbow and shoulder. It is a double-headed muscle, meaning that it has two points of origin or heads in the shoulder area. The short head of each biceps brachii originates at the top of the scapula (at the coracoid process). The long head originates just above the shoulder joint (at the supraglenoid tubercle).

biceps brachii the long fusiform muscle of the upper arm on the anterior surface of the humerus, arising in two heads from the scapula. It flexes the arm and the forearm and supinates the hand. Also called biceps, biceps flexor cubiti. Compare brachialis, triceps brachii.iceps brachii. is a large fusiform muscle lying on the cranial surface of the humerus. Its function is to flex the elbow and integrate the actions of the shoulder and elbow. A medial displacement of the tendon of origin has been reported in dogs, causing a weight-bearing lameness.

The Axilla Region The overall 3D shape of the axilla looks slightly like a pyramid. The borders consist of four sides and a base with an opening at the apex. Apex – Also known as the axillary inlet, this is formed by lateral border of the first rib, superior border of scapula, and the posterior border of the clavicle.

Muscles It is controlled by two muscles, the biceps on the front of the upper arm, and the triceps on the back of the upper arm. The biceps and the triceps are antagonistic muscles. when the biceps muscle contracts, the forearm moves up. when the triceps muscle contracts, the forearm moves down. This solves the problem. To lift the forearm, the biceps contracts and the triceps relaxes.

The Muscles Connecting the Upper Extremity to the Anterior and Lateral Thoracic Walls The muscles of the anterior and lateral thoracic regions are: Pectoralis major. Subclavius. Pectoralis minor. Serratus anterior. Superficial Fascia. The superficial fascia of the anterior thoracic region is continuous with that of the neck and upper extremity above, and of the abdomen below.It encloses the mamma and gives off numerous septa which pass into the gland, supporting its various lobes.t is possible that when the shoulders are fixed the lower fibers of the Serratus anterior may assist in raising and everting the ribs; but it is not the important inspiratory muscle it was formerly believed to be.
