axillaren
Axillaren, in anatomical terms, refers to the axilla or armpit region. It is a pyramidal space that serves as a passageway between the thorax and the upper limb, containing vessels, nerves, lymphatics, and adipose tissue. The axilla acts as a transitional zone through which the upper limb receives its blood supply and nerve innervation while maintaining lymphatic drainage from the arm and portions of the chest and breast.
The borders of the axillaren define its boundaries: the anterior wall is formed primarily by pectoralis major
Functions of the axillaren include supplying the upper limb with arterial blood, draining venous blood back
Etymology derives from the Latin axilla, meaning armpit. The region is routinely imaged via ultrasound or MRI
