You're working on a
skeletal system labeling worksheet. The goal is to match the correct bone names from the “Word Box” to the lines pointing to specific bones in the human skeleton diagram.
---
✔ Here’s how to solve it:
We’ll go
left to right, top to bottom, matching each label line to the correct bone name.
---
🔹 Left Side Labels (from top to bottom):
1.
Top left — Head bone → Skull
✔️ *The skull encloses and protects the brain.*
2.
Next down — Upper arm bone → Humerus
✔️ *The humerus is the long bone of the upper arm, between shoulder and elbow.*
3.
Below that — Forearm bone on thumb side → Ulna
❗ *Wait — actually, this is likely pointing to the
Ulna, which is the inner forearm bone (pinky side), but sometimes people confuse it with Radius. Let’s check the diagram carefully.*
👉 In standard diagrams, the
ulna is the longer bone on the pinky side, and
radius is on the thumb side.
⚠️ *But look at the word box — both are present. We must assign correctly based on position.*
Important: In your image, the label pointing to the
inner forearm (closer to body) is
Ulna. The outer one (thumb side) is
Radius.
4.
Next — Spine / vertebral column → Spine
✔️ *The spine runs down the center of the back and supports the torso.*
5.
Thigh bone → Femur
✔️ *The femur is the longest and strongest bone in the body, from hip to knee.*
6.
Lower leg bone on inner side → Tibia
✔️ *The tibia is the larger shin bone, on the front/inner side of the lower leg.*
---
🔹 Right Side Labels (from top to bottom):
1.
Top right — Shoulder blade → Scapula
✔️ *The scapula is the flat triangular bone on the back of the shoulder.*
2.
Next — Chest cage bones → Ribs
✔️ *Ribs protect the heart and lungs; they attach to the sternum and spine.*
3.
Next — Forearm bone on thumb side → Radius
✔️ *As mentioned, radius is on the thumb side of the forearm.*
4.
Hip bone → Pelvis
✔️ *The pelvis is the bony structure at the base of the spine, connecting the trunk to the legs.*
5.
Lower leg bone on outer side → Fibula
✔️ *The fibula is the thinner bone running alongside the tibia on the outer side of the lower leg.*

✔ Final Correct Labeling:
#### Left Column:
- Top →
Skull
- Second →
Humerus
- Third →
Ulna
- Fourth →
Spine
- Fifth →
Femur
- Sixth →
Tibia
#### Right Column:
- Top →
Scapula
- Second →
Ribs
- Third →
Radius
- Fourth →
Pelvis
- Fifth →
Fibula

📌 Extra Tip:
Some worksheets include
Sternum — which is the breastbone in the center of the chest — but in this diagram, there’s no line pointing to it, so you don’t need to use it.
---
✔ All words used except “Sternum” — which is fine, since not all bones are labeled.

🧠 Why This Matters:
Learning the major bones helps you understand how the body moves, protects organs, and supports posture. It’s foundational for biology, medicine, sports science, and even art!
