What is the axil?

The intersection of the shoulder and the upper arm forms a joint that is movable, allowing a person to achieve, extend and rotate the arm. The cavity under this joint, commonly referred to as an armpit, is called axila. More than just sweat glands and armpits, the axila contains components such as circulatory containers, nerves and lymph nodes. All these elements are contained in the pyramid hollow area between the arm, shoulder and side wall of the chest.

The axillary cavity is bounded by the muscles on both sides. The front, towards the chest, contains pectoralis muscles, while the rear part consists of Latissimus dorsi's muscles at the back. The area is also composed of bony parts that give it a structure, including parts of the upper arm and the bone of the shoulder called the blades. The lower and upper parts of the axillas are also made of ribs of the side walls of the chest and collar bones. The zuzly, which are part of the system that drains lymphn from the upper part of the arm, shoulder and neck. The lymphatic system is used to protect the immunity of the body by moving particles such as JSou bacteria and toxins in the lymph in these specialized channels. Axillary lymph nodes can be swollen, which may be a sign of infection. When lymph nodes carry particles, such as bacteria or cancer cells, it can be a sign of infection or disease and often feels like lump in armpit.

Axila is covered with skin and after puberty has hair growth. Some women are often referred to as "armpits", although this region decides to shave, although cultural attitudes to axillary hair differ. The axila also contains apocrine sweat glands found under the skin. After puberty, it excludes the apocrine glands of sweat under the arm that produces odor when it comes into contact with bacteria on the skin. This reason for many people decides to use an armpit deodorant or antiperspirant to camouflage or prevent some fragrance.

axila contains branches of the main nerve called brachial plexus, a nerve thatIt gives a feeling of most muscles at the top of the arm. As a result, axilla injuries can damage the brachial plexus and affect the feeling of nerve in the upper arm. The armpits also contain axillary artery and axillary vein that runs side by side and are associated with larger blood vessels. Sharp axilla injuries can result in a large amount of blood loss and potential for entering the subclavian vein, which is associated with axillary vein.
