The Skeletal System: Appendicular Division

supporting elements that connect the upper and lower limbs to the trunk

the area where each arm articulates with the trunk

connects the pectoral girdle and the axial skeleton

rough and pyramidal in shape; area from where the clavicle curves in an S shape laterally and dorsally

the end of the clavicle that is broader and flatter than the sternal end

on the inferior surface at the acromial end

at the sternal end

forms a broad triangle with many surface markings reflecting the attachment of muscles, tendons, and ligaments

the upper border of the scapular triangle

the inner border of the scapular triangle that is nearest the body

the outer border of the scapular triangle that is furthest from the body

the upper right hand corner of the scapular triangle

the lower corner of the scapular triangle

head of the scapula; forms a broad process that supports the cup-shaped glenoid cavity, or glenoid fossa

where the scapula articulates with the proximal end of the humerus, the bone of the arm

the articulation where the scapula articulates with the humerus

separates the lateral angle from the body of the scapula

relatively smooth, concave; forms most of the anterior surface of the scapula

a smaller, anterior projection; korakodes - like a crow's beak; projects anteriorly and slightly laterally, and serves as an attachment site

an indentation medial to the base of the coracoid process

akron - tip + omos - shoulder; the larger posterior process, projects anteriorly at a 90 degree angle

where the acromion articulates with the clavicle
