Label the Skeleton Quiz - Free Printable

It looks like you've uploaded a diagram of the human skeletal system with blank labels pointing to various bones. Since I can't view images directly, I’ll help you solve this labeling task based on typical anatomy diagrams of the human skeleton.

Here’s how we can identify and label the major bones in the human skeleton based on common anatomical diagrams:

---

Head & Neck

1. Skull – The entire head bone structure (topmost).
2. Mandible – Lower jawbone.
3. Cervical vertebrae – 7 neck vertebrae (often labeled as "Cervical spine").
4. Clavicle – Collarbone (connects shoulder to sternum).

---

Axial Skeleton (Trunk)

5. Sternum – Breastbone (center of chest).
6. Ribs – Paired bones forming the rib cage.
7. Thoracic vertebrae – Upper back vertebrae (12 pairs of ribs attach here).
8. Lumbar vertebrae – Lower back vertebrae (large, strong).
9. Sacrum – Triangular bone at the base of the spine.
10. Coccyx – Tailbone.

Appendicular Skeleton (Limbs & Girdles)

#### Upper Limb
11. Scapula – Shoulder blade.
12. Humerus – Upper arm bone.
13. Radius – Outer forearm bone.
14. Ulna – Inner forearm bone.
15. Carpals – Wrist bones (8 small bones).
16. Metacarpals – Hand bones (5).
17. Phalanges – Fingers (14 in each hand: 2 in thumb, 3 in others).

#### Lower Limb
18. Pelvis – Hip bone (made of ilium, ischium, pubis).
19. Femur – Thigh bone (longest bone in body).
20. Patella – Knee cap.
21. Tibia – Shin bone (larger of two lower leg bones).
22. Fibula – Smaller lower leg bone (outer side).
23. Tarsals – Ankle bones (7).
24. Metatarsals – Foot bones (5).
25. Phalanges – Toes (14 in each foot: 2 in big toe, 3 in others).

How to Fill the Diagram

Now, match these names to the numbered blanks on your diagram:

- Top to bottom on the left:
1. Skull
2. Mandible
3. Cervical vertebrae
4. Clavicle
5. Scapula
6. Humerus
7. Radius
8. Ulna
9. Carpals
10. Metacarpals
11. Phalanges

- On the right side:
1. Clavicle
2. Sternum
3. Ribs
4. Thoracic vertebrae
5. Lumbar vertebrae
6. Sacrum
7. Coccyx
8. Pelvis
9. Femur
10. Patella
11. Tibia
12. Fibula
13. Tarsals
14. Metatarsals
15. Phalanges

> Note: The exact order may vary slightly depending on how the lines are drawn in your image. But the above list covers all major bones.

Tips for Labeling

- Use standard anatomical terms.
- Be careful with paired bones (like radius/ulna, tibia/fibula).
- Remember that “phalanges” refers to both fingers and toes.
- The pelvis is often labeled as one unit but includes the ilium, ischium, and pubis.

If you can describe which parts are missing or where the lines point, I can give more precise answers!
