Shoulder Anatomy Quiz

Clavicle, scapula, and proximal humerus form the shoulder's skeletal framework.

Broad, superficial muscle connecting scapula and clavicle to the trunk.

Superficial muscle attaching scapula, clavicle to the humerus.

Deep muscles connecting scapula to spine for stability and movement with trapezius.

Elevates, retracts, and rotates the scapula; shrugs shoulders.

Abducts the arm; clavicular fibers flex, posterior fibers extend the arm.

Elevates the scapula.

Elevates and retracts scapula.

Four muscles (supraspinatus, infraspinatus, teres minor, teres major) and long head of triceps brachii. Located deep to trapezius and deltoid, on scapula's posterior.

Supraspinatus, infraspinatus, and teres minor; stabilize the glenohumeral joint.

Abduction of the arm and stabilization of the shoulder joint.

Lateral rotation of the arm and joint stabilization.

Lateral arm rotation and shoulder joint stabilization.

Medial rotation and arm extension at the shoulder.

Extends the elbow and assists in arm extension at the shoulder.

Opening formed by scapula's notch and ligament, allowing passage to the posterior scapular region.

A space connecting the axilla and posterior scapular region, traversed by the axillary nerve and blood vessels.

An area between the axilla and posterior scapular region, containing the circumflex scapular artery and vein.

A space connecting anterior, and posterior arm compartments to the axilla, traversed by the radial nerve and blood vessels.

A nerve originating from the brachial plexus, passing through the suprascapular foramen.

A nerve traveling through the quadrangular space, supplying muscles of the shoulder.

An artery that travels through the quadrangular space, supplying the shoulder.

An artery traversing the Triangular space, supplying the scapula.

Originates from the superior trunk of the brachial plexus, in the base of the neck.

Innervates the supraspinatus muscle.

Originates from the posterior cord of the brachial plexus.

Innervates the deltoid and teres minor muscles.

Found in the posterior scapular region, accompanying the vein.

The suprascapular artery arises from the thyrocervical trunk, a branch of the subclavian artery, or directly from the third part of the subclavian artery.

This artery branches from the axillary artery and travels through the quadrangular space to reach the posterior scapular region.

The suprascapular artery supplies both the supraspinatus and infraspinatus muscles.

The posterior circumflex humeral artery enters the posterior scapular region through the quadrangular space.
