deltoid tuberosity

raised area on lateral surface of humerus to which deltoid muscle attaches

humerus

arm bone

clavicle and scapula

bones of the shoulder girdle

radius and ulna

forearm bones

acromion

scapular region to which the clavicle connects

scapula

shoulder girdle bone that is unattached to the axial skeleton

clavicle

shoulder girdle bone that articulates with and transmits forces to the bony thorax; the “collarbone”

glenoid cavity

depression in the scapula that articulates with the humerus

coronid process

process above the glenoid cavity that permits muscle attachment

trochlea

distal condyle of the humerus that articulates with the ulna

ulna

medial bone of the forearm in anatomical position; forearm bone involved in formation of the elbow joint

capitulum

rounded knob of the humerus that articulates with the radius

coronoid fossa

anterior depression, superior to the trochlea, that receives part of the ulna when the forearm is flexed

carpals

wrist bones

phalanges

finger bones

metacarpals

heads of these bones form the knuckles

scapula and sternum
