Scapular Anatomy Quiz

The most superior border of the scapular region is defined by a horizontal line drawn through the seventh cervical vertebra.

The most inferior border of the scapular region is defined by a horizontal line drawn through the inferior angle of the scapula.

The lateral border of the scapular region is determined by the vertebral border of the scapula extending to the acromion process.

The medial border of the scapular region is defined by the medial margin of the scapula.

The skin in the scapular region is characterized by its thickness and limited movement compared to surrounding areas.

The scapular region comprises the area surrounding the scapula or shoulder blade.

The axillary artery is a major blood vessel supplying the upper limb, originating from the subclavian artery.

The deltoid region refers to the area surrounding the deltoid muscle, a large muscle responsible for shoulder abduction.

A loose connective tissue layer containing subcutaneous fat, superficial nerves and vessels. It is traversed by the skin and supplied by the lateral cutaneous branch of the third intercostal nerve.

A dense, fibrous sheet of two layers. The superficial layer covers the trapezius, deltoid and supraspinatus muscles, while the deep layer covers the suprascapular, infraspinatus, teres minor muscles and rhomboid muscles.

A major artery that runs along the shoulder girdle. It supplies blood to the muscles around the scapula (like supraspinatus and infraspinatus).

A major artery that runs along the shoulder blade. It supplies blood to the muscles around the scapula.

A thin, smooth layer of tissue that contains hair, sweat glands, and subcutaneous glands. It's innervated by the intercostal nerves.

It connects superficial axillary lymph nodes and is traversed by intercostal nerves and medial cutaneous nerves in the arm.

A layer of tissue that surrounds nerves, vessels, and superior axillary lymph nodes. It’s traversed by intercostal nerves, medial cutaneous nerves and lymphatic trunks.

The axillary artery is divided into three sections based on landmarks: the Teres minor muscle, the Pectoralis major muscle, and the lateral border of Teres major. These sections are important for understanding the distribution of blood supply to the upper limb.

The axillary vein is a major vessel that drains blood from the upper limb and joins the subclavian vein to form the brachiocephalic vein. It is formed by the joining of the basilic vein with the brachial vein.

The axillary lymph nodes are strategically located in the axilla (armpit) and serve as filters for lymphatic fluid draining from the upper limb. They are classified into different groups: superior, lateral, central, posterior subscapular, and anterior (medial).

The deltoid region is the area surrounding the deltoid muscle in the shoulder. It has distinct superior, inferior, anterior, and posterior boundaries defined by anatomical landmarks. These boundaries are important for understanding the anatomy and potential locations of structures within the region.

The infraclavicular region (also known as the subclavian region) is located beneath the clavicle and is characterized by its specific boundaries. This region contains important structures such as the subclavian vessels and nerves that supply the upper limb.

The serratus anterior muscle and the first and second intercostal muscles are found in the medial region of the axilla. This medial region is crucial for understanding the anatomy of the axilla and its surrounding structures.

The lateral region of the axilla contains a ridge on the humerus and the fat tissue of the coracobrachialis and subscapularis muscles. This lateral region is significant for comprehending the anatomical relationships between the muscles and bone in the axilla.

The deltoid muscle is covered by the skin and superficial fascia, containing subcutaneous fat, vessels, and nerves. The deltoid muscle itself is covered by deep fascia, which is continuous with the fascia covering the pectoral muscles. This fascia holds veins, arteries, and nerve branches.

The deep fascia covering the pectoralis major muscle, dividing it into two compartments: the circumflex humeral and subscapular compartments.

The space between the clavicle, the coracoid process, and the medial foramen of the clavicle.

A triangular space formed by the trapezius, triceps brachii (long head), and teres major muscles. It contains the axillary and suprascapular nerves.

A space between the lower angle of the scapula, the trapezius muscle, and the Teres major and Teres minor muscles. It contains the axillary artery and the subscapular nerve.

The space formed by the long head of the triceps, the lateral margin of the long head of the triceps, the superior margin of the latissimus dorsi, and the Teres minor muscle. It contains the axillary nerve and posterior circumflex humeral artery.

A freely movable joint characterized by its multi-axial movement capability, allowing flexion, extension, abduction, adduction, rotation, and circumduction.

The anterior border of the shoulder joint is defined by the coracoid process of the scapula.

The medial border of the shoulder joint is in front of the coracoid process of the scapula.

A fibrous sheet that divides the brachial region into anterior and posterior compartments. It's connected to the fascia surrounding the lateral and medial intermuscular septa.

The space between the humerus and the long and lateral heads of the triceps brachii muscle. It contains the radial nerve and the deep brachial artery.

The posterior compartment of the arm is located behind the deep lateral intermuscular septum. It contains the triceps brachii, latissimus dorsi, and the medial epicondyle.

A thick layer of tissue that covers the muscles and nerves in the posterior region of the arm. It's located beneath the superficial fascia.

The region around the elbow joint, containing key landmarks like the medial and lateral epicondyles of the humerus, brachioradialis muscle, and biceps tendon.

The area where the radial nerve, the deep brachial artery, and the radial veins pass through.

The posterior compartment of the arm is located behind the deltoid muscle and the superior surface of the latissimus dorsi muscle.

The anterior compartment of the arm is located in front of the deep lateral intermuscular septum. It contains the biceps brachii, brachialis, and coracobrachialis muscles.

A thick, fibrous sheath covering the muscles and nerves on the dorsal side of the forearm.

A triangular space between the 4th and 5th digits, palmar aponeurosis, and radial nerve.

A triangular area between the flexor carpi ulnaris tendon, flexor digitorum superficialis tendon, and flexor digitorum profundus.

A small space between the flexor carpi ulnaris tendon and the extensor muscles.

A space on the posterosuperior aspect of the forearm.

A triangular area between the flexor digitorum superficialis and flexor digitorum profundus.

It allows movement in two directions, like a ball and socket joint, but with more limited range.

A layer of tissue that encloses the wrist joint.
