Major Divisions of the Body
Cranial – skullInfracranial – the rest of the body
Axial – trunk & head (parts in midline)Appendicular – appendages/ limbs
Includes pelvic and shoulder girdles
Upper LimbClavicleScapulaHumerusRadiusUlnaCarpalsMetacarpalsPhalanges
Clavicle1 right & 1 leftArticulates with sternum medially and scapula laterallyPart of shoulder girdle
Scapula1 right & 1 leftArticulates with clavicle and humerusDoes NOT articulate with ribsPart of shoulder girdle
Humerus 1 right & 1 leftArticulates with scapula, ulna & radius
Ulna1 right & 1 leftArticulates with humerus & radiusConnected to radius by interosseous membraneDoes NOT articulate with carpal bones
Radius1 right & 1 leftArticulates with humerus, ulna, and proximo-lateral aspect of carpal bonesConnected to ulna by interosseous membrane
CarpalsBones of the wrist8 elements (per side)2 rows of 4 Proximal row articulates with radiusDistal row articulates with metacarpals
MetacarpalsBones of the hand5 elements (per side)Articulate with distal row of carpals and phalangesNumbered lateral to medialMC1 – MC5
Manual PhalangesBones of the fingers14 elements (per side)Separated into three rowsProximal phalanges (5)Intermediate phalanges (4)Distal phalanges (5)Singular – phalanx

InnominateOs coxa 1 right & 1 leftArticulate with sacrum posteriorly, other innominate anteriorly, and femur laterally
Innominates3 parts IliumIschiumPubis
Femur1 right & 1 leftConsidered strongest boneArticulates with innominate, tibia, and patella
Patella1 right & 1 leftSesamoid boneArticulates only with femur
Tibia1 right & 1 left Articulates with femur, fibula and talus (tarsal bone)Weight bearing bone of the lower legConnected to fibula with interosseous membrane
Fibula1 right & 1 leftNon-weight bearingArticulates with tibia and talus (tarsal bone)Connected to tibia by interosseous membrane
Tarsals
Bones of the ankle7 elements (per side)Articulate with each other, tibia, fibula, and metatarsals
MetatarsalsBones of the foot5 elements (per side)Numbered medially to laterallyMT1 – MT5 Articulate with tarsals and phalanges
