Where is the axillary artery located in relation to the coracobrachialis muscle?

The axillary artery is anatomically located just behind the coracobrachialis muscle. This positioning is important for understanding both the vascular supply to the upper limb and the clinical relevance during surgical procedures involving the axilla region.

The coracobrachialis muscle arises from the coracoid process of the scapula and serves as a stabilizer of the shoulder joint while also aiding in the flexion and adduction of the arm. Since the axillary artery travels posteriorly to this muscle, it can become a focal point during dissection or when addressing injury to the upper limb. Recognizing this relationship is essential for healthcare professionals as it helps avoid complications during procedures in the shoulder area.

The other choices do not accurately describe the anatomical relationship between the axillary artery and the coracobrachialis, as they suggest positions (such as in front, lateral, or medial) that do not correspond with the established anatomical layout.
