Clavicle
The collarbone
Sternoclavicular Joint
Location where the collarbone meets the breastbone
Acromioclavicular Joint
Location where the collarbone meets the shoulder
Scapula
The shoulder blade
Acromion Process
The large extension that projects from the spine of the scapula
Coracoid Process
The extension that projects from the Glenoid cavity (fossa)
Glenoid Fossa (cavity)
The depression or "socket" of the scapula, where the humerus fits to form the shoulder joint
Spine of the Scapula (or Scapular Spine)
The narrow ridge on the posterior portion of the scapula
Supraspinous Fossa
The depression superior (above) the spine of the scapula
Infraspinous Fossa
The depression inferior (below) the spine of the scapula
Body of the Scapula
The major portion (mostly flat) of the shoulder blade
Humerus
The upper arm bone
Head of the Humerus
The top, rounded portion of the humerus; joins with the Glenoid Fossa (cavity) to form the shoulder joint
Greater Tubercle
The small projection on the lateral, superior side of the Humerus
Shaft of the Humerus
The long portion of the upper arm bone
Deltoid Tuberosity
The rigid portion along the anterior shaft of the humerus, to which the shoulder muscle attaches
Radial Fossa
Small depression on the anterior, lateral, and inferior portion of the humerus, in which the head of the radius fits when the elbow is flexed
Coronoid Fossa
Large depression on the anterior, medial, and inferior portion of the humerus, in which the ulna fits when the elbow is flexed
Lateral Epicondyle
Small projection on the lateral side of the arm, near the radial fossa
Medial Epicondyle
Large projection on the medieal side of the arm, near the coronoid fossa (can sometimes be referred to as the "funny bone")
Capitulum
Rounded projection on the inferior portion of the humerus upon which the radial head moves when the elbow flexes
Trochlea
Large, rounded shape on the inferior portion of the humerus upon whcih the ulna moves when the elbow flexes
Olecranon Fossa
Large depression on the posterior & inferior part of the arm, in which the ulna fits upon elbow extension (when the arm is straightened)
Neck of the Humerus
The narrowed portion of the humerus between the head and shaft of the bone; has 2 parts - the anatomical neck and surgical neck
