Facial bones:
*5. zygomatic bone (2)
*6. superior and inferior maxilla
*9. nasal bone (2)
*7. mandible
*palatine bone (2)
*lacrimal bone (2)
*vomer bone
*inferior nasal conchae (2)

In the middle ears (6):

malleus (2)
incus (2)
stapes (2)

In the throat (1):

hyoid bone

In the shoulder girdle (4):

25. clavicle or collarbone (2)
29. scapula or shoulder blade (2)

In the thorax (25):

10. sternum
28. ribs (2 x 12)

In the vertebral column (24):

8. cervical vertebrae (7) incl. atlas & axis
14. lumbar vertebrae (5)
thoracic vertebrae (12)

In the arms (6):

11. humerus (2)
*26. condyles of humerus
12. ulna (2)
13. radius (2)
*27. head of radius

In the hands (54):

Wrist (carpal) bones:
*scaphoid bone (2)
*lunate bone (2)
*triquetrum bone (2)
*pisiform bone (2)
*Trapezium (bone) (2)
*trapezoid bone (2)
*capitate bone (2)
*hamate bone (2)
Palm or metacarpal bones:
*metacarpal bones (5 × 2)
Finger bones or phalanges:
*proximal phalanges (5 × 2)
*intermediate phalanges (4 × 2)
*distal phalanges (5 × 2)

In the pelvis (4):

15. ilium
16. sacrum
coccyx

In the legs (8):

18. femur (2)
*17. hip joint (joint, not bone) (2)
*22. greater trochanter of femur
*23. condyles of femur
19. patella (2)
20. tibia (2)
21. fibula (2)

In the feet (52):

Ankle (tarsal) bones:
*calcaneus (heel bone) (2)
*talus (2)
*navicular bone (2)
*medial cuneiform bone (2)
*intermediate cuneiform bone (2)
*lateral cuneiform bone (2)
*cuboidal bone (2)
Instep bones:
*metatarsal bone (5 × 2)
Toe bones:
*proximal phalanges (5 × 2)
*intermediate phalanges (4 × 2)
*distal phalanges (5 × 2)

The infant skeleton has the following bones in addition to those above:

sacral vertebrae (4 or 5), which fuse in adults to form the sacrum
coccygeal vertebrae (3 to 5), which fuse in adults to form the coccyx
ilium, ischium and pubis, which fuse in adults to form the pelvic girdle
