Bone Features: Scapula, Clavicle, and Humerus

These flashcards cover the anatomical features of the shoulder girdle and humerus, including landmarks on the scapula, clavicle, and the proximal humerus.

Subscapular fossa

relatively smooth anterior surface of the scapula

Sternal end of Clavicle

joins with the sternum to make the sternoclavicular joint

Greater Tubercle

lateral to the head, provides roundness to the shoulder

Coracoid process

smaller bump on shoulder, more anterior

Spine of the Scapula

the ridge of bone on the posterior aspect, easily palpated, if it can be seen you are looking at a posterior view

Lateral angle

made of the glenoid cavity

Clavicle

collarbone, s shaped for support

Acromial end of Clavicle

broad and flattened, joins with the acromion of the scapula

Superior Angle

between superior and medial borders

Medial border

edge of the scapula closest to the vertebrae

Infraspinous fossa

depression inferior to the spine in the posterior surface

Lesser Tubercle

smaller, more medial to the head

Superior Border

horizontal edge superior to the spine

Lateral border

closest to the armpit

Acromion

bony tip of the shoulder

Supraspinous fossa

depression superior to the spine in the posterior surface

Glenoid cavity

"socket" of the ball and socket joint, connects with the humerus, part of the lateral angle

Deltoid Tuberosity

where the deltoid muscle attatches for about half the lateral length of the humerus

Scapula

shoulder blade; socket must be lateral

Anatomical Neck of Humerus

groove that marks the location of the former epiphyseal plate, weak point on the humerus
