Human skeletal system diagram with posterior and lateral views for anatomical study.

The image you've provided is a labeled diagram of the human skeletal system, showing both posterior (back) view and lateral (side) view. The task appears to be identifying the bones corresponding to each numbered label.

Below is a complete labeling of the numbered structures in both views based on standard human anatomy:

---

Skeletal System – Posterior View (Left Side)

1. Occipital bone – forms the back of the skull
2. Parietal bone – one of the two bones forming the top and sides of the skull
3. Temporal bone – side of the skull, houses the ear
4. Mandible – lower jawbone
5. Clavicle (collarbone) – connects the shoulder blade to the sternum
6. Scapula (shoulder blade) – flat bone on the back of the shoulder
7. Humerus – upper arm bone
8. Ulna – forearm bone (medial side)
9. Radius – forearm bone (lateral side)
10. Carpals – wrist bones
11. Metacarpals – hand bones (between wrist and fingers)
12. Phalanges – finger bones
13. Tarsals – ankle bones
14. Metatarsals – foot bones (between ankle and toes)
15. Phalanges – toe bones
16. Fibula – smaller bone of the lower leg (lateral side)
17. Tibia – larger bone of the lower leg (medial side), weight-bearing
18. Patella – kneecap
19. Femur – thigh bone, longest bone in the body
20. Sacrum – triangular bone at the base of the spine
21. Coccyx (tailbone) – small bone at the bottom of the spine
22. Ilium – upper part of the hip bone
23. Ischium – lower and posterior part of the hip bone
24. Pubis – anterior part of the hip bone
25. Lumbar vertebrae – five large vertebrae in the lower back
26. Thoracic vertebrae – 12 vertebrae in the upper and mid-back
27. Cervical vertebrae – 7 vertebrae in the neck
28. Ribs – 12 pairs, attach to thoracic vertebrae
29. Sternum (breastbone) – flat bone in the center of the chest
30. Acromion process – projection of the scapula that forms the tip of the shoulder
31. Spine of scapula – ridge running across the back of the scapula
32. Vertebral column (spine) – series of vertebrae from neck to tailbone
33. Atlas (C1) – first cervical vertebra, supports the skull
34. Axis (C2) – second cervical vertebra, allows rotation of the head
35. Foramen magnum – large opening in the occipital bone where the spinal cord enters the skull

Skeletal System – Lateral View (Right Side)

36. Calcaneus – heel bone
37. Talus – bone above the calcaneus, articulates with the tibia and fibula
38. Navicular – bone in the midfoot
39. Femur – thigh bone
40. Patella – kneecap
41. Tibia – shin bone
42. Fibula – thinner bone next to the tibia
43. Humerus – upper arm bone
44. Scapula – shoulder blade
45. Clavicle – collarbone
46. Cervical vertebrae – neck region
47. Thoracic vertebrae – upper and mid-back
48. Lumbar vertebrae – lower back
49. Sacrum – fused vertebrae at the base of the spine
50. Coccyx – tailbone
51. Pelvis – hip bone formed by ilium, ischium, and pubis
52. Ribs – curved bones connecting to thoracic vertebrae
53. Sternum – breastbone
54. Manubrium – upper part of the sternum
55. Body of sternum – long central part
56. Xiphoid process – small cartilaginous tip of the sternum
57. Carpals – wrist bones
58. Metacarpals – hand bones
59. Phalanges – finger bones
60. Tarsals – ankle bones
61. Metatarsals – foot bones
62. Phalanges – toe bones

> ⚠️ Note: The lateral view has labels starting from 36 onward, but some numbers may be missing or misaligned in your diagram. Based on typical diagrams, the numbering continues from 36 upward, with the most common structure being the calcaneus (36), talus (37), etc., as listed above.
