What are the main parts of the shoulder?

The shoulder is made of three bones (clavicle, scapula, humerus), the glenohumeral and acromioclavicular joints, the four rotator cuff muscles, the deltoid and surrounding muscles, the glenoid labrum, the joint capsule with its ligaments, and the subacromial bursa. This tool can label all of these.

What are the four rotator cuff muscles?

The rotator cuff is the supraspinatus, infraspinatus, teres minor, and subscapularis, often remembered as SITS. They attach the scapula to the top of the humerus and keep the humeral head centered in the socket as the arm moves.

What is the glenoid labrum?

The glenoid labrum is a ring of fibrocartilage around the edge of the glenoid socket. It deepens the socket so the humeral head sits more securely, and it is a point of attachment for the joint capsule and ligaments.

What is the subacromial bursa?

The subacromial bursa is a thin fluid-filled sac between the acromion and the rotator cuff tendons. It reduces friction as the arm lifts. It is often drawn in diagrams explaining shoulder impingement.

Can I use the diagrams in patient handouts?

They work as teaching illustrations, but AI-generated labels can be wrong or point slightly off. Check every label against a trusted anatomy reference before sharing, and keep clinical advice separate from the diagram. The examples on this page note the flaws we found.

Shoulder Anatomy Examples

AI-generated examples of the bones, rotator cuff, joint, ligaments, and muscles of the shoulder, with the label flaws we found noted on each

View:

Shoulder Bones and Joints

AI-generated example. Known flaws: the "Glenohumeral joint" pointer lands on the scapular neck rather than the joint gap, the "Manubrium" leader points at the sternal body, the "Lesser tubercle" leader stops in the gap between the humeral head and glenoid, and the sternum is drawn longer and narrower than real.

Rotator Cuff (SITS)

AI-generated example. Subscapularis is shown on the front of the scapula; supraspinatus, infraspinatus, and teres minor on the back. The infraspinatus arrow ends at the scapular edge, next to the muscle.

Joint Cross-Section

AI-generated example. The labrum is stylized as an oval ring around the glenoid, and the bursa is simplified; use it as a patient-talk sketch, not a surgical reference.

Shoulder Ligaments

AI-generated example. Known flaw: the "Acromioclavicular ligament" arrow lands on the middle of the clavicle instead of the AC joint at its outer end.

Muscles Around the Shoulder

AI-generated example. The sternum at the right edge is drawn loosely; the labeled muscles sit where expected.

What does a shoulder anatomy diagram show?

A shoulder anatomy diagram shows how the bones, joints, muscles, tendons, and soft tissues of the shoulder girdle fit together. A typical labeled diagram includes the clavicle (collarbone), scapula (shoulder blade) with its acromion, coracoid process, and glenoid, and the humerus (upper arm bone). It also shows the acromioclavicular (AC) joint, the glenohumeral (ball-and-socket) joint, the four rotator cuff muscles, the labrum, the joint capsule, and the subacromial bursa. This generator creates clear, labeled shoulder diagrams for patient explanations, physiotherapy and orthopedic teaching, and anatomy study.

The structures of the shoulder

Bones: the clavicle, scapula, and humerus meet at the shoulder. The acromion and coracoid process are bony projections of the scapula; the glenoid is the shallow socket that the rounded humeral head sits in.
Joints: the glenohumeral joint is the main ball-and-socket joint. The acromioclavicular (AC) joint links the collarbone to the acromion, and the sternoclavicular joint links the collarbone to the sternum.
Rotator cuff: supraspinatus, infraspinatus, teres minor, and subscapularis (remembered as SITS) hold the humeral head in the socket and rotate and lift the arm.
Soft tissue: the glenoid labrum is a rim of fibrocartilage that deepens the socket, the joint capsule and glenohumeral ligaments stabilize it, and the subacromial bursa cushions the rotator cuff tendons beneath the acromion.

The rotator cuff: SITS

The rotator cuff is four muscles whose tendons blend around the humeral head. The supraspinatus sits above the spine of the scapula and starts lifting the arm. The infraspinatus and teres minor lie below the spine on the back of the scapula and rotate the arm outward. The subscapularis fills the front surface of the scapula and rotates the arm inward. The supraspinatus tendon passes under the acromion, which is why it is the tendon most often shown in impingement and tear explanations.

Using shoulder diagrams for patient education and teaching

Patient handouts: a simple labeled diagram of the rotator cuff and bursa helps explain where pain comes from, before you describe the plan.
Physiotherapy and orthopedic teaching: label the muscle attachments you want students to learn, then generate a front view and a back view for the same lesson.
Anatomy and sports-science courses: compare the bone, ligament, and muscle layers of the same joint in separate diagrams.
Review every generated label before you share it. These are teaching illustrations, not medical imaging, and they do not replace clinical advice.

Tips for a clear shoulder diagram

Name the view (front, back, or cross-section), the side (right shoulder is the usual default), and the exact structures to label. Ask for one layer at a time, such as bones only, or rotator cuff only, since a single image with every layer gets crowded. Generate a few options, check each label line points at the right structure, and download the clearest one for your handout, slide, or worksheet.
