Skeletal system worksheet - Free Printable

Let’s go step by step to match each bone name to its correct position on the skeleton diagram.

We have these bone names to place:
- PELVIS
- CRANIUM
- RADIUS
- VERTEBRAE
- TIBIA
- STERNUM
- FIBULA
- CLAVICLE
- SCAPULA
- RIBS
- HUMERUS
- PATELLA
- ULNA

Now, let’s look at the skeleton from top to bottom and match each label:

1. Top of head → That’s the skull. The scientific name is CRANIUM.
2. Shoulder area (top front) → That’s the collarbone → CLAVICLE.
3. Behind the shoulder (back side) → That’s the shoulder blade → SCAPULA.
4. Chest center (vertical bone) → That’s the breastbone → STERNUM.
5. Rib cage (curved bones around chest) → Those are the RIBS.
6. Spine (backbone running down center) → Those are the VERTEBRAE.
7. Upper arm bone (from shoulder to elbow) → That’s the HUMERUS.
8. Forearm bone on thumb side → That’s the RADIUS.
9. Forearm bone on pinky side → That’s the ULNA.
10. Hip area (bony ring) → That’s the PELVIS.
11. Thigh bone (longest bone, from hip to knee) → That’s the FEMUR.
12. Kneecap (small bone in front of knee) → That’s the PATELLA.
13. Lower leg bone (shin bone, larger one) → That’s the TIBIA.
14. Lower leg bone (smaller one, next to tibia) → That’s the FIBULA.

Now, let’s assign them to the boxes in order from top to bottom as they appear on the diagram (left side first, then right side):

Left side (top to bottom):
- Box 1 (head) → CRANIUM
- Box 2 (shoulder front) → CLAVICLE
- Box 3 (chest center) → STERNUM
- Box 4 (rib cage) → RIBS
- Box 5 (spine) → VERTEBRAE
- Box 6 (upper arm) → HUMERUS
- Box 7 (forearm, thumb side) → RADIUS
- Box 8 (thigh) → FEMUR
- Box 9 (lower leg, shin) → TIBIA

Right side (top to bottom):
- Box 1 (shoulder back) → SCAPULA
- Box 2 (spine side) → VERTEBRAE? Wait — no, we already used vertebrae. Actually, looking again — the spine is one structure, so maybe the right-side box pointing to spine is also vertebrae? But we can only use each once. Let’s recheck.

Actually, let’s list all 14 boxes and map them properly:

From top to bottom, left to right:

Left column:
1. Head → CRANIUM
2. Shoulder (front) → CLAVICLE
3. Chest center → STERNUM
4. Rib cage → RIBS
5. Spine → VERTEBRAE
6. Upper arm → HUMERUS
7. Forearm (thumb side) → RADIUS
8. Thigh → FEMUR
9. Lower leg (shin) → TIBIA

Right column:
1. Shoulder (back) → SCAPULA
2. Spine (same as left? No — actually, the right-side box near spine might be pointing to the same vertebrae? But we can’t duplicate. Wait — perhaps the right-side box near spine is actually pointing to the pelvis? No, pelvis is lower.

Wait — let’s count the boxes: There are 14 boxes total.

List of bones available: 14 names.

So each box gets one unique bone.

Let’s assign based on standard anatomical labeling:

Top row:
- Left: CRANIUM (head)
- Right: SCAPULA (shoulder blade)

Second row:
- Left: CLAVICLE (collarbone)
- Right: RIBS (rib cage — but ribs are multiple, so maybe this box points to the rib cage area)

Wait — better to go by position:

Actually, looking at typical diagrams:

- Top: CRANIUM
- Below that, left: CLAVICLE
- Below that, left: STERNUM
- Below that, left: RIBS
- Below that, left: VERTEBRAE (spine)
- Below that, left: HUMERUS (upper arm)
- Below that, left: RADIUS (forearm, thumb side)
- Below that, left: FEMUR (thigh)
- Below that, left: TIBIA (shin)

Right side:
- Top: SCAPULA (shoulder blade)
- Below that: RIBS? No — already used. Wait — perhaps the right-side box near spine is pointing to the same vertebrae? But we can’t.

I think I made a mistake. Let me recount the boxes visually from the image description.

Actually, since I can't see the image, I'll rely on standard labeling for such worksheets.

Standard matching for this type of worksheet:

Left side (top to bottom):
1. CRANIUM
2. CLAVICLE
3. STERNUM
4. RIBS
5. VERTEBRAE
6. HUMERUS
7. RADIUS
8. FEMUR
9. TIBIA

Right side (top to bottom):
1. SCAPULA
2. RIBS? No — wait, perhaps the second right box is pointing to the pelvis? No.

Wait — there are 14 boxes. Let me list them as per common layout:

Actually, let's think differently. The bones are:

Cranium, Clavicle, Sternum, Ribs, Vertebrae, Humerus, Radius, Ulna, Pelvis, Femur, Patella, Tibia, Fibula, Scapula.

Now, positions:

- Head: Cranium
- Shoulder front: Clavicle
- Shoulder back: Scapula
- Chest center: Sternum
- Rib cage: Ribs
- Spine: Vertebrae
- Upper arm: Humerus
- Forearm thumb side: Radius
- Forearm pinky side: Ulna
- Hip: Pelvis
- Thigh: Femur
- Kneecap: Patella
- Shin: Tibia
- Calf bone: Fibula

Now, assign to boxes:

Assuming the diagram has:

Left side (9 boxes):
1. Head → Cranium
2. Shoulder front → Clavicle
3. Chest center → Sternum
4. Rib cage → Ribs
5. Spine → Vertebrae
6. Upper arm → Humerus
7. Forearm (thumb) → Radius
8. Thigh → Femur
9. Lower leg (shin) → Tibia

Right side (5 boxes):
1. Shoulder back → Scapula
2. Spine? No — perhaps the next is pelvis? But pelvis is lower.

Wait — perhaps the right side has:

After scapula, then ribs? But ribs are already on left.

I think I need to accept that without seeing the exact diagram, I'll use the most logical assignment.

But since this is a common worksheet, I recall that:

The boxes are typically labeled as:

Top: Cranium

Then left: Clavicle, Sternum, Ribs, Vertebrae, Humerus, Radius, Femur, Tibia

Right: Scapula, Ribs (but duplicate? No), wait — perhaps the right side has Scapula, then Vertebrae again? No.

Another approach: count the number of boxes per side.

From the user's image description, there are 14 boxes.

Bones: 14 names.

So each bone is used once.

Let me assign based on anatomy:

- Cranium: head
- Clavicle: shoulder front
- Scapula: shoulder back
- Sternum: chest center
- Ribs: rib cage
- Vertebrae: spine
- Humerus: upper arm
- Radius: forearm, thumb side
- Ulna: forearm, pinky side
- Pelvis: hip
- Femur: thigh
- Patella: kneecap
- Tibia: shin
- Fibula: calf

Now, in the diagram, the boxes are placed as:

Left side (from top to bottom):
1. Head → Cranium
2. Shoulder front → Clavicle
3. Chest center → Sternum
4. Rib cage → Ribs
5. Spine → Vertebrae
6. Upper arm → Humerus
7. Forearm (thumb) → Radius
8. Thigh → Femur
9. Lower leg (shin) → Tibia

Right side (from top to bottom):
1. Shoulder back → Scapula
2. Spine? No — perhaps the next is pelvis? But pelvis is not on right side usually.

Wait — perhaps the right side has:

After scapula, then the box pointing to the rib cage on the right? But ribs are already assigned.

I think there's a mistake in my assumption.

Let me look for a different strategy.

Perhaps the boxes are:

Left:
- Cranium
- Clavicle
- Sternum
- Ribs
- Vertebrae
- Humerus
- Radius
- Femur
- Tibia

Right:
- Scapula
- Ulna
- Pelvis
- Patella
- Fibula

That makes 14.

And it makes sense because:

- Ulna is forearm pinky side, which might be on the right side of the diagram if the skeleton is facing forward.
- Pelvis is hip, which could be on the right.
- Patella is kneecap, on the right.
- Fibula is calf, on the right.

Yes, that works.

So final assignment:

Left side (top to bottom):
1. CRANIUM
2. CLAVICLE
3. STERNUM
4. RIBS
5. VERTEBRAE
6. HUMERUS
7. RADIUS
8. FEMUR
9. TIBIA

Right side (top to bottom):
1. SCAPULA
2. ULNA
3. PELVIS
4. PATELLA
5. FIBULA

This covers all 14 bones.

Now, to confirm:

- Cranium: head ✓
- Clavicle: shoulder front ✓
- Sternum: chest center ✓
- Ribs: rib cage ✓
- Vertebrae: spine ✓
- Humerus: upper arm ✓
- Radius: forearm thumb side ✓
- Femur: thigh ✓
- Tibia: shin ✓
- Scapula: shoulder back ✓
- Ulna: forearm pinky side ✓
- Pelvis: hip ✓
- Patella: kneecap ✓
- Fibula: calf ✓

Perfect.

Final Answer:
CRANIUM, CLAVICLE, STERNUM, RIBS, VERTEBRAE, HUMERUS, RADIUS, FEMUR, TIBIA, SCAPULA, ULNA, PELVIS, PATELLA, FIBULA

But since the task is to drag and drop, and the boxes are in specific positions, I'll list them in the order they appear in the diagram from top to bottom, left to right.

Assuming the diagram has left column first, then right column:

Left column (9 boxes):
1. CRANIUM
2. CLAVICLE
3. STERNUM
4. RIBS
5. VERTEBRAE
6. HUMERUS
7. RADIUS
8. FEMUR
9. TIBIA

Right column (5 boxes):
1. SCAPULA
2. ULNA
3. PELVIS
4. PATELLA
5. FIBULA

So the final answer is the list of bones in that order.

But since the user might expect the names matched to the boxes, and there's no box numbering, I'll provide the sequence as above.

For the final answer, I'll write the bones in the order they should be placed, assuming left to right, top to bottom.

Final Answer:
CRANIUM, CLAVICLE, STERNUM, RIBS, VERTEBRAE, HUMERUS, RADIUS, FEMUR, TIBIA, SCAPULA, ULNA, PELVIS, PATELLA, FIBULA
