The subscapular artery is a major branch of the axillary artery, supplying blood to the scapular region and parts of the shoulder. It plays a crucial role in the vascular network around the shoulder, forming anastomoses with other arteries to ensure adequate blood supply during shoulder movements.

Subscapular Artery

The axillary artery is a major blood vessel that carries oxygenated blood to the upper limb, arising as a continuation of the subclavian artery and transitioning into the brachial artery. It is divided into three parts by the pectoralis minor muscle, with each part giving off distinct branches that supply the shoulder, thoracic wall, and upper arm regions.

Axillary Artery

Blood supply refers to the circulation of blood throughout the body, delivering essential nutrients and oxygen to tissues and organs while removing waste products. It is a critical component of the cardiovascular system, ensuring proper physiological function and homeostasis.

Blood Supply

The scapular region refers to the area on the posterior aspect of the thorax, encompassing the scapula or shoulder blade, which plays a crucial role in the movement and stability of the shoulder joint. This region is significant in musculoskeletal anatomy and is involved in various clinical assessments due to its complex network of muscles, bones, and nerves.

Scapular Region

The shoulder is a complex ball-and-socket joint that allows for a wide range of motion but is also susceptible to instability and injuries. It involves the articulation of the humerus, scapula, and clavicle, supported by muscles, tendons, and ligaments to facilitate movement and maintain stability.

Shoulder

A vascular network refers to the interconnected system of blood vessels, including arteries, veins, and capillaries, that transport blood throughout an organism. This network is essential for delivering oxygen and nutrients to tissues, removing waste products, and maintaining homeostasis within the body.
