Skeletal System Lesson Plans & Worksheets :: 25 - 48 - Free Printable

It looks like you've uploaded a crossword puzzle related to the Skeletal System. Since I can't view images directly, I’ll help you solve the crossword based on the clues and structure you’ve provided in your text.

Let me reconstruct and solve the crossword puzzle using the clues:

Crossword: Skeletal System

#### Across
1. makes bones strong → Calcium
2. long upper leg bone → Femur
3. appendage joint that allows movement → Hinge
4. 1 finger → Digit
5. joint that allows bones to glide → Gliding
6. joints that move only in one direction → Hinge
7. connects bones → Ligament
8. joint that allows any direction of motion → Ball and socket
9. joins 2 or more bones → Joint
10. connects bones to muscles → Tendon
11. parts of bones and cartilage → Cells
12. 206 bones → Skeleton

#### Down
1. part of a bone → Cartilage
2. joint that moves only on one plane → Hinge
3. shape of long bones → Shaft
4. joint made with ball and socket → Ball and socket
5. type of joint → Gleiding (likely typo for Gliding)
6. joint → Joint
7. joint → Joint
8. joint → Joint
9. joint → Joint
10. hinge, gliding → Types of joints

---

Wait — let's re-analyze this carefully. The grid has 12 Across clues and 10 Down clues, but some clues are repeated or possibly mislabeled. Let’s correct and logically fill the crossword.

But since the image isn't visible, I will assume a standard layout and use common skeletal system vocabulary.

Let’s go clue by clue.

Revised Clues & Answers

#### Across
1. makes bones strong → Calcium
*(Important mineral for bone strength)*

2. long upper leg bone → Femur
*(Longest bone in the body)*

3. appendage joint that allows movement → Hinge
*(Like elbow or knee)*

4. 1 finger → Digit
*(Each finger/toe is a digit)*

5. joint that allows bones to glide → Gliding
*(Also called plane joint; e.g., wrist)*

6. joints that move only in one direction → Hinge
*(Same as #3, likely a repeat)*

7. connects bones → Ligament
*(Connects bone to bone)*

8. joint that allows any direction of motion → Ball and socket
*(Shoulder and hip joints)*

9. joins 2 or more bones → Joint
*(General term)*

10. connects bones to muscles → Tendon
*(Connects muscle to bone)*

11. parts of bones and cartilage → Cells
*(Bone and cartilage are made of cells)*

12. 206 bones → Skeleton
*(Total number of bones in adult human body)*

---

#### Down
1. part of a bone → Cartilage
*(Found at joint ends, nose, ears)*

2. joint that moves only on one plane → Hinge
*(Same as across 3 and 6)*

3. shape of long bones → Shaft
*(The middle part of a long bone is the shaft)*

4. joint made with ball and socket → Ball and socket
*(Repeating answer)*

5. type of joint → Gliding
*(Plane joint)*

6. joint → Joint
*(Generic, possibly filler)*

7. joint → Joint
*(Likely same as above)*

8. joint → Joint
*(Possibly a mistake or placeholder)*

9. joint → Joint
*(Again, may be a typo or error)*

10. hinge, gliding → Types of joints
*(This seems to be a category clue, possibly not fitting into a single word)*

Likely Issue:

The "Down" clues from 6–9 just say “joint” — that’s odd. Possibly a formatting issue. Also, clue 10 says “hinge, gliding” — which might mean it’s looking for a type of joint, but the answer could be gliding or plane.

Alternatively, perhaps the clue is meant to be:
> 10. Type of joint: hinge, gliding, ball and socket → Joint types

But that doesn’t fit well in a crossword.

Let’s consider a better possibility.

Maybe the down clues are:

- Down 1: part of a bone → Cartilage
- Down 2: joint that moves only on one plane → Hinge
- Down 3: shape of long bones → Shaft
- Down 4: joint made with ball and socket → Ball and socket
- Down 5: type of joint → Gliding
- Down 6: connects bone to bone → Ligament
- Down 7: connects muscle to bone → Tendon
- Down 8: joint → Joint
- Down 9: joint → Joint
- Down 10: hinge, gliding → Types of joints → But again, too long.

Alternatively, maybe Down 10 is asking for a word that includes both “hinge” and “gliding” — but that doesn’t make sense.

Wait — perhaps Down 10 is supposed to be:

> 10. Hinge, gliding, ball and socket — all are types of... → Joints

So answer: Joints

That fits better.

Final Answer Key:

#### Across
1. Calcium
2. Femur
3. Hinge
4. Digit
5. Gliding
6. Hinge
7. Ligament
8. Ball and socket
9. Joint
10. Tendon
11. Cells
12. Skeleton

#### Down
1. Cartilage
2. Hinge
3. Shaft
4. Ball and socket
5. Gliding
6. Ligament
7. Tendon
8. Joint
9. Joint
10. Joints

Notes:

- Some answers repeat (like "Hinge", "Joint") — common in crosswords.
- "Shaft" is correct for the central part of a long bone.
- "Cells" is acceptable for "parts of bones and cartilage".
- "Skeleton" is the correct term for the total of 206 bones.
- "Digits" = fingers/toes.

Final Crossword Grid (Conceptual)

Since I can’t draw it, here’s how the grid would look roughly:

```
C A L C I U M
F E M U R G L I D I N G
H I N G E S H A F T
D I G I T B A L L A N D S O C K E T
G L I D I N G J O I N T
H I N G E T E N D O N
L I G A M E N T C E L L S
B A L L A N D S O C K E T
J O I N T
T E N D O N
C E L L S
S K E L E T O N
```

But actual layout depends on the grid size.

✔ Summary:

The crossword focuses on anatomy of the skeletal system, including:
- Bones (femur, skeleton)
- Joints (hinge, gliding, ball and socket)
- Connective tissues (ligaments, tendons)
- Bone composition (calcium, cartilage, cells)

If you have the actual grid or need help filling it in visually, feel free to describe the grid size or provide the letters already filled. Otherwise, this solution should match most versions of this popular science crossword.
