13.  bony expansion carried on a narrow neck
14.  large, rounded projection
15.  raised area on or above a condyle
16.  very large, blunt, irregularly shaped process, only found on the femur
17.  small, rounded projection or process
18.  a narrow junction often found between two bones, like the bones of the skull
19  narrow, usually prominent, ridge of bone
20.  the part of a bone that connects the head to the rest of the bone

Accepted Answer

To solve this, we identify the correct bone markings for each description:

### 13. Bony expansion carried on a narrow neck
This is a **condyle**? No, wait—"bony expansion on a narrow neck" is a *head*? No, correction: The term for a bony expansion carried on a narrow neck is **condyle**? Wait, no—let's recall:
- **Head**: Bony expansion carried on a narrow neck (articulates with another bone). Wait, no, "head" is the rounded end, but "bony expansion on a narrow neck" is actually the **head**? Wait, no, let's check standard bone markings:
  - **Head**: Rounded, expanded end (carried on a neck). Wait, the description here is "bony expansion carried on a narrow neck"—so **Head**? No, maybe I mixed up. Wait, let's list standard bone markings:
  - **Condyle**: Rounded projection (articulating).
  - **Tuberosity**: Large, rounded projection.
  - **Epicondyle**: Raised area on/above condyle.
  - **Trochanter**: Very large, blunt, irregular (only on femur).
  - **Tubercle**: Small, rounded projection.
  - **Suture**: Narrow junction (skull bones).
  - **Crest**: Narrow, prominent ridge.
  - **Neck**: Connects head to rest of bone.
  Wait, re-matching:

13. *Bony expansion carried on a narrow neck* → **Head** (but wait, "neck" connects head to bone. Wait, no—"bony expansion (head) carried on a narrow neck (the neck of the bone)". So 13: **Head**? Wait, no, maybe the options (dropdowns) have these terms. Let's assume the dropdown options include: Head, Condyle, Epicondyle, Trochanter, Tubercle, Suture, Crest, Neck, etc.

### 14. *Large, rounded projection* → **Tuberosity** (large, rounded projection for muscle attachment).

### 15. *Raised area on or above a condyle* → **Epicondyle** (epi- means "above", so raised area above a condyle).

### 16. *Very large, blunt, irregularly shaped process, only found on the femur* → **Trochanter** (specific to femur, large irregular process).

### 17. *Small, rounded projection or process* → **Tubercle** (small, rounded, for muscle/tendon attachment).

### 18. *A narrow junction often found between two bones, like the bones of the skull* → **Suture** (fibrous joint between skull bones, narrow junction).

### 19. *Narrow, usually prominent, ridge of bone* → **Crest** (narrow, prominent ridge, e.g., iliac crest).

### 20. *The part of a bone that connects the head to the rest of the bone* → **Neck** (connects the head (rounded end) to the diaphysis/shaft).

### Final Answers (matching each number):
13. Head (or check dropdown; if options include "Head", that’s it)
14. Tuberosity
15. Epicondyle
16. Trochanter
17. Tubercle
18. Suture
19. Crest
20. Neck

(Note: If dropdown options differ, adjust based on standard bone marking definitions.)

### Step-by-Step Explanation for Each:
1. **13**: Define "bony expansion on narrow neck" → matches *Head* (rounded end connected by a neck).
2. **14**: "Large, rounded projection" → *Tuberosity* (large, rounded for muscle attachment).
3. **15**: "Raised area on/above condyle" → *Epicondyle* (epi- = above, so above condyle).
4. **16**: "Very large, blunt, irregular (femur only)" → *Trochanter* (unique to femur).
5. **17**: "Small, rounded projection" → *Tubercle* (small, rounded).
6. **18**: "Narrow junction (skull)" → *Suture* (fibrous joint between skull bones).
7. **19**: "Narrow, prominent ridge" → *Crest* (e.g., iliac crest).
8. **20**: "Connects head to bone" → *Neck* (the narrow part connecting head to diaphysis).

### Final Answers (each number):
13. Head
14. Tuberosity
15. Epicondyle
16. Trochanter
17. Tubercle
18. Suture
19. Crest
20. Neck

Question

Explanation:

13. Bony expansion carried on a narrow neck

14. Large, rounded projection → Tuberosity (large, rounded projection for muscle attachment).

15. Raised area on or above a condyle → Epicondyle (epi- means "above", so raised area above a condyle).

16. Very large, blunt, irregularly shaped process, only found on the femur → Trochanter (specific to femur, large irregular process).

17. Small, rounded projection or process → Tubercle (small, rounded, for muscle/tendon attachment).

18. A narrow junction often found between two bones, like the bones of the skull → Suture (fibrous joint between skull bones, narrow junction).

19. Narrow, usually prominent, ridge of bone → Crest (narrow, prominent ridge, e.g., iliac crest).

20. The part of a bone that connects the head to the rest of the bone → Neck (connects the head (rounded end) to the diaphysis/shaft).
