4Drag and drop the correct answers to describe the borders of the axilla.
The apex/axillary inlet is formed by the [blank_start]lateral[blank_end] border of the [blank_start]first[blank_end] rib, the superior border of the [blank_start]scapula[blank_end] and posterior border of the [blank_start]clavicle[blank_end].
The lateral border is the [blank_start]intertubercular sulcus[blank_end] of the humerus.
The medial border is the [blank_start]serratus anterior[blank_end] muscle and thoracic wall.
The anterior border is pectoralis major and minor as well as [blank_start]subclavius[blank_end].
The posterior border is subscapularis, [blank_start]teres major[blank_end] and latissimus dorsi.
The base is formed by the [blank_start]axillary fossa[blank_end] or the skin of the armpit.- Afirst
