1. acetabulum large, cup-shaped cavity located on the lateral side of the hip bone; formed by the junction of the ilium, pubis, and ischium portions of the hip bone
2. acromial end of the clavicle lateral end of the clavicle that articulates with the acromion of the scapula
3. acromial process acromion of the scapula
4. acromioclavicular joint articulation between the acromion of the scapula and the acromial end of the clavicle
5. acromion flattened bony process that extends laterally from the scapular spine to form the bony tip of the shoulder
6. adductor tubercle small, bony bump located on the superior aspect of the medial epicondyle of the femur
7. anatomical neck line on the humerus located around the outside margin of the humeral head
8. ankle joint joint that separates the leg and foot portions of the lower limb; formed by the articulations between the talus bone of the foot inferiorly, and the distal end of the tibia, medial malleolus of the tibia, and lateral malleolus of the fibula superiorly
9. anterior border of the tibia narrow, anterior margin of the tibia that extends inferiorly from the tibial tuberosity
10. anterior inferior iliac spine small, bony projection located on the anterior margin of the ilium, below the anterior superior iliac spine
11. anterior sacroiliac ligament strong ligament between the sacrum and the ilium portions of the hip bone that supports the anterior side of the sacroiliac joint
12. anterior superior iliac spine rounded, anterior end of the iliac crest
13. apical ectodermal ridge enlarged ridge of ectoderm at the distal end of a limb bud that stimulates growth and elongation of the limb
14. arcuate line of the ilium smooth ridge located at the inferior margin of the iliac fossa; forms the lateral portion of the pelvic brim
15. arm region of the upper limb located between the shoulder and elbow joints; contains the humerus bone
16. auricular surface of the ilium roughened area located on the posterior, medial side of the ilium of the hip bone; articulates with the auricular surface of the sacrum to form the sacroiliac joint
17. base of the metatarsal bone expanded, proximal end of each metatarsal bone
18. bicipital groove intertubercular groove; narrow groove located between the greater and lesser tubercles of the humerus
19. calcaneus heel bone; posterior, inferior tarsal bone that forms the heel of the foot
20. capitate from the lateral side, the third of the four distal carpal bones; articulates with the scaphoid and lunate proximally, the trapezoid laterally, the hamate medially, and primarily with the third metacarpal distally
21. capitulum knob-like bony structure located anteriorly on the lateral, distal end of the humerus
22. carpal bone one of the eight small bones that form the wrist and base of the hand; these are grouped as a proximal row consisting of (from lateral to medial) the scaphoid, lunate, triquetrum, and pisiform bones, and a distal row containing (from lateral to medial) the trapezium, trapezoid, capitate, and hamate bones
23. carpal tunnel passageway between the anterior forearm and hand formed by the carpal bones and flexor retinaculum
24. carpometacarpal joint articulation between one of the carpal bones in the distal row and a metacarpal bone of the hand
25. clavicle collarbone; elongated bone that articulates with the manubrium of the sternum medially and the acromion of the scapula laterally
26. coracoclavicular ligament strong band of connective tissue that anchors the coracoid process of the scapula to the lateral clavicle; provides important indirect support for the acromioclavicular joint
27. coracoid process short, hook-like process that projects anteriorly and laterally from the superior margin of the scapula
28. coronoid fossa depression on the anterior surface of the humerus above the trochlea; this space receives the coronoid process of the ulna when the elbow is maximally flexed
29. coronoid process of the ulna projecting bony lip located on the anterior, proximal ulna; forms the inferior margin of the trochlear notch
30. costoclavicular ligament band of connective tissue that unites the medial clavicle with the first rib
