The Structure of the Skeleton worksheet for learning human anatomy with labeled bones and blank spaces to fill in.

Let's solve this step-by-step by identifying the missing labels on the skeleton diagram based on the provided key words and anatomical positions.

---

Step 1: Understand the Diagram

There are two views of the human skeleton:
- Left side: Anterior (front) view
- Right side: Posterior (back) view

We need to label the bones indicated by arrows using the Key Words list.

Step 2: Identify the Labels Using Anatomical Knowledge

We’ll go through each blank in order from top to bottom, left to right.

#### Anterior View (Left Side)

1. Top arrow pointing to skull (face):
→ This is the Cranium (the skull).

2. Arrow pointing to shoulder bone (on side):
→ The Scapula (shoulder blade), located on the back, but visible in anterior view.

3. Arrow pointing to upper arm bone:
→ Humerus (upper arm bone between shoulder and elbow).

4. Arrow pointing to forearm bone (inner side):
→ Ulna (medial forearm bone).

5. Arrow pointing to forearm bone (outer side):
→ Radius (lateral forearm bone).

6. Arrow pointing to wrist bones:
→ Carpals (small bones in the wrist).

7. Arrow pointing to hand bones (in palm):
→ Metacarpals (bones of the hand between wrist and fingers).

8. Arrow pointing to finger bones:
→ Phalanges (bones of the fingers).

9. Arrow pointing to thigh bone:
→ Femur (longest bone in the body, upper leg).

10. Arrow pointing to knee cap:
→ Patella (kneecap).

11. Arrow pointing to lower leg bone (inner side):
→ Tibia (shin bone).

12. Arrow pointing to lower leg bone (outer side):
→ Fibula (thin bone next to tibia).

13. Arrow pointing to foot bones (in arch):
→ Tarsals (bones of the ankle/foot).

14. Arrow pointing to foot bones (between ankle and toes):
→ Metatarsals (bones of the foot).

15. Arrow pointing to toe bones:
→ Phalanges (toe bones).

#### Posterior View (Right Side)

16. Arrow pointing to spine:
→ Vertebral Column (spine).

17. Arrow pointing to shoulder blade (visible clearly here):
→ Scapula.

18. Arrow pointing to collarbone:
→ Clavicle.

19. Arrow pointing to rib cage:
→ Ribs.

20. Arrow pointing to breastbone (center of chest):
→ Sternum.

21. Arrow pointing to hip bone (pelvic region):
→ Pelvis.

22. Arrow pointing to femur (thigh bone):
→ Femur.

23. Arrow pointing to patella (knee cap):
→ Patella.

24. Arrow pointing to fibula (lower leg):
→ Fibula.

25. Arrow pointing to tibia (shin):
→ Tibia.

26. Arrow pointing to heel bone (calcaneus):
→ Tarsals (specifically part of the tarsal bones).

27. Arrow pointing to metatarsals (foot):
→ Metatarsals.

28. Arrow pointing to phalanges (toes):
→ Phalanges.

8. Phalanges
9. Femur
10. Patella
11. Tibia
12. Fibula
13. Tarsals
14. Metatarsals
15. Phalanges

#### Posterior View (Right Side) – From Top to Bottom:
16. Vertebral Column
17. Scapula
18. Clavicle
19. Ribs
20. Sternum
21. Pelvis
22. Femur
23. Patella
24. Fibula
25. Tibia
26. Tarsals
27. Metatarsals
28. Phalanges

22. Femur
23. Patella
24. Fibula
25. Tibia
26. Tarsals
27. Metatarsals
28. Phalanges

📌 Notes:

- Some bones appear multiple times (e.g., Scapula, Femur, Phalanges) because they are labeled in both views.
- The key word "Humerus" is already highlighted in red in the list — it’s one of the most important bones to identify.

This labeling helps students learn the major bones of the axial and appendicular skeleton.
