Appendicular Skeleton Upper Appendicular Skeleton Bone Lower Appendicular Skeleton Bone SimilaritiesDifferences ClavicleIschium/Pubis ScapulaIlium HumerusFemur RadiusTibia UlnaFibula CarpalsTarsals MetacarpalsMetatarsals Phalanges Pectoral Girdle Clavicle collarbone Anterior attachment (?) Posterior attachment (?) Scapula shoulder blades Posterior attachment (?) Spine divides posterior surface into 2 sections Coracoid process (Corac = ?) curves to clavicle Acromion process forms tip of shoulder Glenoid cavity (or fossa) depression that articulates with head of humerus Label Diagrams Upper Limb Humerus Radius Ulna Carpals Metacarpals Phalanges Humerus Head fits into glenoid cavity of scapula Greater tubercle lateral process Lesser tubercle more anterior process Intertubercular groove narrow furrow between tubercles Deltoid tuberosity v-shaped, rough area where _________ muscles attach to humerus Olecranon fossa posterior depression that receives an ulnar process when elbow is straightened Coronoid fossa anterior depression that receives a radial process when elbow is bent Radius Shorter bone of lower arm Located on thumb side of arm Disc-like head articulates with humeru and with radial notch of the ulna (so your arm can rotate) Radial tuberosity, a process below the head, provides attachment for biceps Styloid process at distal end; attachment for wrist ligaments Ulna Longer than radius Overlaps distal end of humerus posteriorly Proximal end has a wrenchlike opening called the trochlear notch (articulates w/humerus) Oleacronon process top process Coronoid process bottom process Radial notch just below trochlear notch Head at distal end; articulates with ulnar notch of radius Styloid process attachment for wrist ligaments Label Diagrams Wrist Wrist made of 8 carpal bones Some lovers try positions that they cant handle. Scaphoid Lunate Triquetrum Pisiform Trapezium Trapezoid Capitate Hamate Hand 5 metacarpals Numbered 1-5, starting at thumb Bones between wrist (carpals) and fingers (?) Rounded distal ends form knuckles Each finger, except thumb, has 3 phalanges: Proximal phalanx Middle phalanx Distal phalanx Thumb only has no middle phalanx.
