Shoulder Joint Anatomy Quiz

A type of synovial joint that allows for a wide range of movements, such as flexion, extension, abduction, adduction, rotation, and circumduction.

The head of the humerus articulates with the glenoid cavity of the scapula. The glenoid labrum, a ring-like structure, deepens the glenoid cavity.

It attaches to the margins of the glenoid cavity medially and to the anatomical neck of the humerus laterally.

The shoulder joint capsule has two openings. One allows the tendon of the biceps brachii to pass through, and the other connects to the subscapular bursa.

The superior, middle, and inferior glenohumeral ligaments, coracohumeral ligament, and transverse humeral ligament.

The suprascapular, axillary, and posterior circumflex humeral arteries.

The suprascapular, axillary, and radial nerves.

Flexion, extension, abduction, adduction, internal rotation, external rotation, and circumduction.

A fibrous sac that surrounds the tendon of the long head of the biceps brachii muscle, allowing smooth gliding of the tendon within the joint capsule.

A strong ligament that extends from the coracoid process of the scapula to the greater tubercle of the humerus. It helps to stabilize the shoulder joint.

A bony arch formed by the coracoid process, acromion process, and coracoacromial ligament. It provides protection to the supraspinatus tendon and helps stabilize the shoulder joint.

Ligaments, capsule, and the surrounding muscles, especially the rotator cuff muscles, play a crucial role in stabilizing and providing support to the shoulder joint.

The anterior and posterior circumflex humeral arteries and branches of the suprascapular artery provide blood supply to the shoulder joint.

The nerves supplying the shoulder joint are typically the same nerves that supply the muscles that move the joint. This is known as Hilton's law.

The shoulder joint is classified as a ball and socket joint. This allows for a wide range of movements.

The shoulder joint allows for movements like flexion, extension, abduction, adduction, medial rotation, and lateral rotation. These movements are facilitated by muscles like the deltoid, pectoralis major, latissimus dorsi, subscapularis, and infraspinatus.

The shoulder joint, a ball-and-socket joint formed by the head of the humerus and the glenoid cavity of the scapula.

Two openings, one for the tendon of the biceps brachii muscle and the other for the passage of nerves and blood vessels.

Fibrous tissues that connect bones, providing stability and limiting movement.

A strong ligament that strengthens the superior aspect of the shoulder joint. It connects the coracoid process of the scapula to the acromion.

These ligaments reinforce the anterior aspect of the shoulder joint, helping prevent dislocation.

The shoulder joint is innervated by several nerves, including branches of the axillary, suprascapular, and dorsal scapular nerves.
