Anatomical terminology

The axilla (or armpit, underarm, or oxter) is the area on the human body directly under the joint where the arm connects to the shoulder. It also provides the under-arm sweat gland.

Structure[edit]

Boundaries[edit]

Anatomically, the boundaries of the axilla are:

superiorly: by the outer border of first rib, superior border of scapula, and posterior border of clavicle[1]
medially: serratus anterior[2] and by the ribcage anteriorly: by the pectoralis major, minor,[3] and subclavius[2]

posteriorly: by the subscapularis above, and teres major and latissimus dorsi below[2]

laterally: by the intertubercular sulcus[3] (coracobrachialis and the short head of the biceps brachii are in the axilla.)[2]
floor/base: by the skin[1] (visible surface of armpit)

The lower posterior boundary is called the posterior axillary fold and this is a compound structure consisting of the latissimus dorsi and teres major muscles.[4]It can descend after weight loss.[5]

The anterior boundary is called the anterior axillary fold and this is rounded in shape and formed by the lower border of the pectoralis major. Some sources also include the pectoralis minor.[6]It can elongate after weight loss.[7]

The contents of the axilla include the axillary vein and artery, as well as the brachial plexus, lymph nodes and fat. The axilla is the space between the side of the thorax and the upper arm.

Contents[edit]

Society and culture[edit]

The term "underarm" typically refers to the outer surface of the axilla. However, the terms are sometimes used interchangeably in casual contexts. Colloquially, armpit refers to the hollow beneath the junction of the arm and shoulder.[8]

The term oxter is used in the Scots language instead of "armpit".[9]

Tickling[edit]

Main article: Tickling

Armpit or underarm is a rather ticklish area, most likely due to the amount nerves. Some people find especially this area unpleasant when tickled.

Underarm hair[edit]

Main article: Underarm hair

Underarm hair usually grows in the underarms of both females and males, beginning in adolescence.

Clinical significance[edit]

Axillary intertrigo[edit]

Excessive perspiration can result in axillary intertrigo. Intertrigo is an inflamed skin condition caused by heat, friction, and moisture.[10] A warm, wet armpit may accommodate the growth of pathogenic bacteria, yeasts, and fungi.[11] The condition is responsible for rash-like symptoms, pustules, or chronic itching or burning in the armpit.[10] Axillary intertrigo is common among those who work in hot environments.[11]
