For your test, you should be able to identify each appendage as right or left. Pectoral Girdle: clavice scapula Bone markings: acromial and sternal end of clavicle spine of scapula acromion corocoid process glenoid fossa Upper Limbs: humerus radius carpals (8) metacarpals (5) phalanges (14) Pollex – thumb; has only proximal and distal phalanges other fingers have 3 bones – proximal, medial and distal; numbered 1-5 beginning with thumb Bone markings: Radius: Humerus: radial tuberosity greater and lesser tubercle head of radius deltoid tuberosity styloid process capitulum Ulna: trochlea radial notch medial and lateral epicondyles olecranon process olecranon fossa trochlear notch head of humerus styloid process coronoid process Pelvic Girdle: Identify the differences between male and female pelvic bones ilium ischium pubis Bone markings: Iliac crest pubic symphysis Iliac fossa sacroiliac joint obturator foramen acetabulum ischial tuberosity Lower Limbs: Bone markings: femur greater and lesser trochanter (femur) tibia lateral and medial epicondyle (femur) fibula head of femur (prox) and patellar groove (dis) patella lateral and medial condyle (tibia) tarsals (7) tibial tuberosity calcaneus crest of tibia talus medial and lateral malleolus (tibia/fibula) metatarsals numbered 1 – 5 medial to lateral phalanges (14) numbered 1 – 5 medial to lateral hallux is # 1 (big toes) only proximal and medial phalanges proximal, medial, and distal phalanx on 2 - 5
