Skeletal System online activity for 7 - Free Printable

Let's solve this step by step. The image is a labeled human skeleton diagram with blank lines pointing to various bones, and a list of 16 bone names provided at the bottom. Our task is to match each label (numbered from 1 to 16) with the correct bone name based on its location in the body.

---

Step 1: Identify the locations of the bones

We'll go through each numbered label and determine which bone it corresponds to based on the diagram.

1. Femur – This is the thigh bone, the longest bone in the body. It connects the hip to the knee.
→ Located in the upper leg.

2. Collarbone – Also known as the clavicle. It connects the shoulder blade to the sternum.
→ Horizontal bone at the top of the chest, near the shoulders.

3. Radius – One of the two bones in the forearm (the other is the ulna). It's on the thumb side.
→ Forearm, outer side.

4. Ribs – Curved bones that form the ribcage, protecting the heart and lungs.
→ On the sides of the chest, attached to the spine and sternum.

5. Tibia – The shinbone, the larger and stronger of the two lower leg bones.
→ Front of the lower leg, above the ankle.

6. Cranium – The skull, which protects the brain.
→ Top of the head.

7. Kneecap – Also called the patella. It's a small bone in front of the knee joint.
→ In the knee area.

8. Pelvis – The basin-shaped structure that supports the spine and connects to the legs.
→ Hip region, below the spine.

9. Fibula – The thinner bone in the lower leg, running parallel to the tibia.
→ Outer side of the lower leg.

10. Ulna – The inner forearm bone (on the pinky side).
→ Forearm, opposite the radius.

11. Breastbone – Also called the sternum. It’s the flat bone in the center of the chest.
→ Middle of the chest, connected to the ribs.

12. Spinal Column – Also known as the backbone or vertebral column.
→ Runs down the back from the neck to the pelvis.

13. Humerus – The bone in the upper arm, between the shoulder and elbow.
→ Upper arm.

14. Metacarpals – Bones in the hand, between the wrist and fingers.
→ Hand, palm area.

15. Metatarsals – Bones in the foot, between the ankle and toes.
→ Foot, arch area.

16. Shoulder Blade – Also called the scapula. A flat triangular bone on the back of the shoulder.
→ Back, near the shoulder.

Step 2: Match labels to positions on the diagram

Now we’ll assign each bone name to the correct position on the skeleton:

- Top of the head: Cranium → Label 6
- Back of the head/neck: Spinal Column → Label 12
- Center of the chest (vertical): Breastbone (Sternum) → Label 11
- Sides of the chest: Ribs → Label 4
- Shoulder blades (back): Shoulder Blade → Label 16
- Clavicles (collarbones): Horizontal bones at the top of the chest → Label 2
- Upper arms: Humerus → Label 13
- Forearms (thumb side): Radius → Label 3
- Forearms (pinky side): Ulna → Label 10
- Hands (between wrist and fingers): Metacarpals → Label 14
- Thighs: Femur → Label 1
- Knees: Kneecap → Label 7
- Shin (front of lower leg): Tibia → Label 5
- Outer lower leg: Fibula → Label 9
- Feet (between ankle and toes): Metatarsals → Label 15
- Hip bones: Pelvis → Label 8

Final Answer Key:

Now, matching each "Type answer here" box to the correct bone name:

From top to bottom, left to right:

1. Cranium → Top of head
2. Humerus → Upper arm (left)
3. Radius → Forearm (left, thumb side)
4. Metacarpals → Hand (left)
5. Femur → Thigh (left)
6. Tibia → Lower leg (left, front)
7. Fibula → Lower leg (left, outer side)
8. Metatarsals → Foot (left)

On the right side:

9. Shoulder Blade → Back, shoulder
10. Spinal Column → Backbone
11. Ribs → Side of chest
12. Breastbone → Center chest
13. Collarbone → Top of chest
14. Pelvis → Hip
15. Kneecap → Knee
16. Ulna → Forearm (right, pinky side)

Wait — let's double-check the labeling order.

Looking closely at the diagram:

- The first label is at the top of the head → Cranium
- Then going down the left arm: Humerus → Radius → Metacarpals
- Then left leg: Femur → Tibia → Fibula → Metatarsals
- On the right side: Shoulder Blade → Spinal Column → Ribs → Breastbone → Collarbone → Pelvis → Kneecap → Ulna

But note: Some labels are on the right side, others on the left.

Let’s go by the lines:

1. Top line → Cranium (6)
2. Left side, just below head → Humerus (13)
3. Left forearm → Radius (3)
4. Left hand → Metacarpals (14)
5. Left thigh → Femur (1)
6. Left lower leg (front) → Tibia (5)
7. Left lower leg (outer) → Fibula (9)
8. Left foot → Metatarsals (15)

Right side:

9. Right shoulder blade → Shoulder Blade (16)
10. Spine → Spinal Column (12)
11. Right side of chest → Ribs (4)
12. Center chest → Breastbone (11)
13. Right collarbone → Collarbone (2)
14. Pelvis → Pelvis (8)
15. Right kneecap → Kneecap (7)
16. Right forearm (inner) → Ulna (10)

So now, fill in the blanks in order:

Top to bottom, left to right:

1. Cranium
2. Humerus
3. Radius
4. Metacarpals
5. Femur
6. Tibia
7. Fibula
8. Metatarsals
9. Shoulder Blade
10. Spinal Column
11. Ribs
12. Breastbone
13. Collarbone
14. Pelvis
15. Kneecap
16. Ulna

✔ Final Answer:

| Label | Bone Name |
|-------|------------------|
| 1 | Cranium |
| 2 | Humerus |
| 3 | Radius |
| 4 | Metacarpals |
| 5 | Femur |
| 6 | Tibia |
| 7 | Fibula |
| 8 | Metatarsals |
| 9 | Shoulder Blade |
| 10 | Spinal Column |
| 11 | Ribs |
| 12 | Breastbone |
| 13 | Collarbone |
| 14 | Pelvis |
| 15 | Kneecap |
| 16 | Ulna |

Now, place these answers into the corresponding yellow boxes on the diagram in the same order as the lines point.

Summary:

You should type the following in the boxes in the order they appear from top to bottom:

1. Cranium
2. Humerus
3. Radius
4. Metacarpals
5. Femur
6. Tibia
7. Fibula
8. Metatarsals
9. Shoulder Blade
10. Spinal Column
11. Ribs
12. Breastbone
13. Collarbone
14. Pelvis
15. Kneecap
16. Ulna

This completes the labeling of the human skeleton diagram correctly.
