Educational human skeleton diagram worksheet for learning bone names.

It looks like you've uploaded an image of a human skeleton labeling worksheet. The task appears to be labeling the bones of the human skeleton using the provided word bank on the right side of the page.

Here's how to solve this problem:

🔍 Step-by-Step Solution:

#### ✔ Objective:
Label each part of the human skeleton on the second diagram (middle panel) using the correct bone names from the word bank.

#### 📌 Word Bank (Given):
- Sternum
- Mandible
- Cervical vertebrae
- Sternum
- Scapula
- Thoracic cage
- Humerus
- Radius
- Ulna
- Carpal
- Metacarpal
- Phalanges
- Sacrum
- Pelvis
- Femur
- Patella
- Tibia
- Fibula
- Tarsal
- Phalanges

> Note: Some terms are repeated (e.g., "Sternum" appears twice), but that’s likely for redundancy or error correction.

🧠 How to Label the Skeleton:

We’ll go through the major bones and match them to their locations on the skeleton diagram.

#### 1. Head & Neck:
- Mandible → Lower jawbone
- Cervical vertebrae → Neck bones (7 in total)
- Skull → Not listed, but implied; not needed here

#### 2. Thorax (Chest):
- Sternum → Breastbone
- Scapula → Shoulder blade
- Clavicle → Collarbone (not in word bank? Wait — it is missing!)
- ❗️Wait: “Clavicle” is not in the word bank, but it should be labeled.
- However, the word bank includes “Thoracic cage”, which refers to the ribcage (ribs + sternum).

> ⚠️ Note: The word bank does not include *clavicle* or *rib*, but it does have:
> - Thoracic cage – this may be used to label the entire ribcage area
> - Sternum – already included

So perhaps “Thoracic cage” is meant to label the ribs and sternum together.

#### 3. Upper Limbs (Arms):
- Humerus → Upper arm bone
- Radius → Forearm bone (thumb side)
- Ulna → Forearm bone (palm side)
- Carpal → Wrist bones
- Metacarpal → Hand bones (between wrist and fingers)
- Phalanges → Fingers (including thumbs)

#### 4. Pelvic Region:
- Sacrum → Triangular bone at base of spine
- Pelvis → Hip bone (made of ilium, ischium, pubis — but labeled as "Pelvis")
- Femur → Thigh bone (longest bone in body)

#### 5. Lower Limbs (Legs):
- Patella → Knee cap
- Tibia → Shin bone (larger of two leg bones)
- Fibula → Thin bone next to tibia
- Tarsal → Ankle bones
- Phalanges → Toes

✔ Correct Labels by Position:

Now, let’s assign labels to the blank boxes on the middle diagram (second skeleton):

#### Top to Bottom, Left to Right:

| Area | Bone Name |
|------|----------|
| Head (jaw) | Mandible |
| Neck | Cervical vertebrae |
| Chest (center) | Sternum |
| Shoulders (back) | Scapula |
| Clavicles? | Not in word bank — possibly omitted |
| Upper arms | Humerus |
| Forearms (outer) | Radius |
| Forearms (inner) | Ulna |
| Wrists | Carpal |
| Hands (middle) | Metacarpal |
| Fingers | Phalanges |
| Ribs (chest) | Thoracic cage (used for whole ribcage) |
| Lower back | Sacrum |
| Hip bones | Pelvis |
| Thighs | Femur |
| Knees | Patella |
| Shins (front) | Tibia |
| Shins (side) | Fibula |
| Ankles | Tarsal |
| Toes | Phalanges |

🛠️ Final Answer:

You need to fill in the blanks on the middle skeleton diagram with these labels in the correct positions:

1. Mandible → Jaw
2. Cervical vertebrae → Neck
3. Sternum → Breastbone
4. Scapula → Shoulder blades
5. Humerus → Upper arm
6. Radius → Outer forearm
7. Ulna → Inner forearm
8. Carpal → Wrist
9. Metacarpal → Palm bones
10. Phalanges → Fingers
11. Thoracic cage → Ribcage area
12. Sacrum → Base of spine
13. Pelvis → Hip
14. Femur → Thigh
15. Patella → Knee cap
16. Tibia → Shin (main bone)
17. Fibula → Thin lower leg bone
18. Tarsal → Ankle
19. Phalanges → Toes

> 💡 Tip: Use "Phalanges" twice — once for fingers and once for toes.

🧩 Important Notes:

- The word bank has two "Sternum" entries — probably a typo or duplication.
- Clavicle is missing from the word bank — unusual, but maybe assumed.
- Rib is not listed, but "Thoracic cage" can represent the ribs and sternum together.

✔ Final Advice:

Match each blank box to the correct bone based on its location. For example:
- The topmost blank near the jaw → Mandible
- The long bone in the thigh → Femur
- The small bones in the hand and foot → Phalanges

If you’re filling this out physically, use the left diagram (labeled) as a guide.
