The axilla (pl.: axillae or axillas; also known as the armpit, underarm or oxter) is the area on the human body directly under the shoulder joint.It includes the axillary space, an anatomical space within the shoulder girdle between the arm and the thoracic cage, bounded superiorly by the imaginary plane between the superior borders of the first rib, clavicle and scapula (above which are ...
The true axilla is a conical space with its apex at the Cervico-axillary Canal, Base at the axillary fascia and skin of the armpit. When viewed in an axillary plane (axillary cut), it is more triangle with: Medial Wall: Serratus Anterior, Anterior Wall: pectoral muscles, Posterior Wall: subscapularis muscle, where the "apex" of the triangle is the humerus [4] [5]
the fibular region encompassing the outside of the lower leg, the tarsal region encompassing the ankle, the pedal region encompassing the foot; the digital/phalangeal region encompassing the toes. The great toe is referred to as the hallux. The regions of the upper limbs, from superior to inferior, are the axillary region encompassing the armpit,
The axillary joints are two joints in the axillary region of the body, and include the shoulder joint and the acromioclavicular joint.
The quadrangular space is a clinically important anatomic space in the arm as it provides the anterior regions of the axilla a passageway to the posterior regions. In the quadrangular space, the axillary nerve and the posterior humeral circumflex artery can be compressed or damaged due to space-occupying lesions or disruption in the anatomy due to trauma.
Axillary lines. Vertical lines: Midline, lateral sternal line, parasternal line and midclavicular line. Horizontal lines: Level of the sternal angle, and zipho-sternal line. Anatomical "lines", or "reference lines," are theoretical lines drawn through anatomical structures and are used to describe anatomical location.
The axillary nerve supplies two muscles in the arm: deltoid (a muscle of the shoulder) and teres minor (one of the rotator cuff muscles). The axillary nerve also carries sensory information from the shoulder joint. It also innervates the skin, covering the inferior region of the deltoid muscle, known as the regimental badge area. [9]
