What does axillary area mean?

armpit area
Listen to pronunciation. (AK-sih-LAYR-ee) Pertaining to the armpit area, including the lymph nodes that are located there.

What is the axilla?

Introduction. 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 are the types of axillary?

There are five axillary lymph node groups, namely the lateral (humeral), anterior (pectoral), posterior (subscapular), central and apical nodes.

What is the axillary process of breast?

The tail of Spence (Spence’s tail, axillary process, axillary tail) has historically been described as an extension of the tissue of the upper lateral quadrant of the breast traveling into the axilla.

Is axillary anterior or posterior?

The axillary nerve (C5-6) is also a branch of the posterior cord, and innervates the deltoid and teres minor muscles. It also supplies sensation over the regimental patch area of the shoulder.

What are axillary hairs?

Armpit hair, also referred to as axillary hair, gets its start from puberty. Around ages 10–12 for females and 11–14 for males, the pituitary gland triggers a group of hormones called androgens in the ovaries and testicles.

What are axillary walls?

There are five anatomic borders of the axilla: the superior, anterior, posterior, lateral, and medial walls. The medial wall is the serratus anterior and the first four ribs. The humerus, the coracobrachialis, and the short head of the biceps form the lateral wall.

Where is the axillary fold?

The axillary fold (plica axillaris) is the skin fold situated at the caudal aspect of the thoracic limb immediately proximal to the elbow. It has medial and lateral attachments to the front limb and dorsal and ventral attachments to the body wall.

What is the difference between axillary and axilla?

The floor, or base, of the axilla is the axillary fascia and its skin on the surface of the axilla, aka the ‘armpit’. The axilla is filled with adipose (fat) and allows passage for: vessels, nerve plexus, lymphatics, and muscles. The muscles include the coracobrachialis, pectoralis minor, and the biceps brachii.

What is the axillary fascia?

The axillary fascia is relatively dense, especially in the central third of the shoulder and below the deltoid muscle. It divides at the lateral margin of the latissimus dorsi muscle into two layers, which ensheaths the muscle and are attached posteriorly to the spinous processes of the thoracic vertebrae.

What is axillary lymph node?

(AK-sih-LAYR-ee limf node) A lymph node in the armpit region that drains lymph from the breast and nearby areas.

Is axillary part of trunk or arm?

The axilla is the space between the side of the thorax and the upper arm.

What is the anatomy of the axilla?

It is a passageway by which neurovascular and muscular structures can enter and leave the upper limb. In this article, we shall examine the anatomy of the axilla – the borders, contents, and any clinical correlations.

What is a lamella in biology?

In surface anatomy, a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. Aside from respiratory organs, they appear in other biological roles including filter feeding and the traction surfaces of geckos.

What is the axillary region of the arm?

It is a quadrilateral space which changes shape based upon whether the arm is adducted or abducted. The lymph nodes of the axillary region are responsible for the lymphatic drainage of a large section of human anatomy.

What is the function of the axillary wall?

The brachial plexus, a network of nerves originating from the C5-T1 spinal roots, is the principal nervous structure in the axillary area. The axillary walls are used as landmarks by surgeons to prevent damage to the neurovascular structures within the axilla during surgery.
