Which anatomical structures are involved in the deltopectoral triangle?

The deltopectoral triangle is an anatomical region located between the deltoid and pectoralis major muscles. The structures that are primarily associated with this triangle include the cephalic vein, which drains the upper extremity and is notable for its course through this area. The pectoral nerve, responsible for innervating portions of the pectoralis major and minor muscles, is also found within this triangle. The reference to the clavicular artery, while less commonly mentioned than the other structures, relates to nearby vascular supply around the clavicle region.

Understanding the components of the deltopectoral triangle is important for recognizing its relevance in clinical settings, such as during procedures like venipuncture or surgeries in the shoulder area, where these structures can be located and potentially affected. Additionally, the knowledge of anatomical relationships aids in better understanding the layout of the upper limb.
