Muscles of the Shoulder
This large, triangular muscle covers the shoulder and is responsible for lifting the arm away from the body.
What is the deltoid?
This bone connects the shoulder to the neck and supports the arm.
What is the clavicle?
This joint is where the clavicle meets the sternum.
What is the sternoclavicular joint?
This nerve innervates the deltoid and teres minor muscles.
What is the axillary nerve?
This movement involves raising the arm sideways, away from the body.
What is abduction?
This muscle is part of the rotator cuff and is involved in external rotation of the shoulder.
What is the infraspinatus?
This bony structure, part of the scapula, forms the highest point of the shoulder.
What is the acromion?
The ball-and-socket joint of the shoulder.
What is the glenohumeral joint?
This nerve controls the serratus anterior muscle, essential for stabilizing the scapula.
What is the long thoracic nerve?
This movement brings the arm toward the midline of the body.
What is adduction?
This muscle lies on the anterior side of the scapula and is responsible for internal rotation.
What is the subscapularis?
This shallow socket in the scapula forms part of the shoulder’s ball-and-socket joint.
What is the glenoid cavity or fossa?
This ligament stabilizes the shoulder by connecting the acromion to the clavicle.
What is the acromioclavicular ligament?
This nerve originates from the brachial plexus and supplies the subscapularis muscle.
What is the upper subscapular nerve?
This type of movement occurs when you rotate the arm outward, away from the body.
What is external rotation?
This muscle helps lift the scapula and is located on the back and side of the neck.
What is the levator scapulae?
This bony structure is the insertion for 3 of the 4 rotator cuff muscles
What is the greater tubercle or tuberosity.
The structure that deepens the glenoid cavity, helping to stabilize the shoulder joint.
What is the glenoid labrum?
This large nerve passes through the shoulder region but primarily supplies the muscles of the forearm.
What is the radial nerve?
This movement allows you to reach up to scratch your lower back by rotating your arm inward.
What is internal rotation?
This small rotator cuff muscle aids in shoulder extension and external rotation.
What is the teres minor?
This bony structure (be specific) serves as the origin of the teres major.
What is the inferior angle of the scapula?
These ligament connects the coracoid process of the scapula to the clavicle. (Name the complex and each individual ligament)
What is the coracoclavicular ligament?
Conoid Ligament & Trapezoid ligament
This nerve provides sensation to the skin over the shoulder and upper arm and also controls shoulder movement.
What is the suprascapular nerve?
This motion, performed by the deltoid and supraspinatus, allows you to lift your arm above your head.
What is flexion and abduction?
