Axial and Appendicular Skeleton Coloring (Grade 10) - Free ... - Free Printable

The image you've uploaded is a labeled anatomical diagram of the human hand skeleton, showing the bones of the hand from the dorsal (back) view. The task appears to be to label the bones of the hand, which are indicated by lines pointing to various structures.

Let’s go through the anatomy of the hand and identify each bone:

---

Bones of the Hand:

1. Phalanges – These are the bones of the fingers.
- Each finger has three phalanges: proximal, middle (intermediate), and distal.
- The thumb (pollex) has only two phalanges: proximal and distal.
- From the top down:
- Distal phalanx (tip of finger)
- Middle phalanx (middle segment)
- Proximal phalanx (base of finger)

2. Metacarpals – These are the five long bones in the palm that connect the phalanges to the wrist.
- Numbered 1–5 from thumb to little finger.

3. Carpals – Eight small bones in the wrist arranged in two rows.
- Proximal row (from lateral to medial):
- Scaphoid
- Lunate
- Triquetrum
- Pisiform (a sesamoid bone on top of the triquetrum)
- Distal row (from lateral to medial):
- Trapezium
- Trapezoid
- Capitate
- Hamate

Labeling Guide Based on Diagram:

Starting from the top (fingers) and moving down to the wrist:

#### Fingers (from left to right — assuming this is a right hand):
- Thumb (index finger on far left):
- Topmost bone → Distal phalanx
- Middle bone → Proximal phalanx
- Bottom bone → Metacarpal I (thumb metacarpal)

- Index finger:
- Distal phalanx
- Middle phalanx
- Proximal phalanx
- Metacarpal II

- Middle finger:
- Distal phalanx
- Middle phalanx
- Proximal phalanx
- Metacarpal III

- Ring finger:
- Distal phalanx
- Middle phalanx
- Proximal phalanx
- Metacarpal IV

- Pinker (little finger):
- Distal phalanx
- Middle phalanx
- Proximal phalanx
- Metacarpal V

#### Wrist Bones (Carpals):
From the lateral side (thumb side) to medial (palm side):

- Trapezium – articulates with the thumb metacarpal
- Trapezoid
- Capitate – largest carpal bone
- Hamate – has a hook-like process
- Scaphoid – most commonly fractured carpal bone
- Lunate
- Triquetrum
- Pisiform – sits on top of the triquetrum

In the diagram, the lines point to these bones in order.

Step-by-step Labeling (based on line positions):

Assuming the labels go from top to bottom (as shown by the vertical scale):

1. Distal phalanx of little finger
2. Middle phalanx of little finger
3. Proximal phalanx of little finger
4. Metacarpal V
5. Hamate
6. Capitate
7. Trapezium
8. Trapezoid
9. Scaphoid
10. Lunate
11. Triquetrum
12. Pisiform
13. Metacarpal I (thumb)
14. Proximal phalanx of thumb
15. Distal phalanx of thumb

> ⚠️ Note: The exact order depends on how many lines are drawn. If there are only 10 lines, then likely it's labeling the five metacarpals and five proximal phalanges, or perhaps the carpals and metacarpals.

But based on typical textbook diagrams like this one (from Pearson/Benjamin Cummings), the lines usually label:

- The five metacarpals (I–V)
- The eight carpals (in order)
- Possibly the phalanges of the fingers

However, since the lines extend from the wrist up, and some point to phalanges, we can deduce:

✔ Final Answer (Most Likely Labels):

Assuming the vertical lines correspond to the following from top to bottom:

| Line | Bone |
|------|------|
| 1 | Distal phalanx of little finger |
| 2 | Middle phalanx of little finger |
| 3 | Proximal phalanx of little finger |
| 4 | Metacarpal V |
| 5 | Hamate |
| 6 | Capitate |
| 7 | Trapezium |
| 8 | Trapezoid |
| 9 | Scaphoid |
| 10 | Lunate |
| 11 | Triquetrum |
| 12 | Pisiform |
| 13 | Metacarpal I (thumb) |
| 14 | Proximal phalanx of thumb |
| 15 | Distal phalanx of thumb |

But if there are only 10 lines, then likely:

1. Distal phalanx (any finger)
2. Middle phalanx
3. Proximal phalanx
4. Metacarpal
5. Trapezium
6. Trapezoid
7. Capitate
8. Hamate
9. Scaphoid
10. Lunate

And possibly the pisiform and triquetrum are missing.

🔍 Conclusion:

To solve the problem:

✔ Identify the bones using standard hand anatomy.
✔ Match the lines to the correct bone names.
✔ Start from the fingertips and work down to the wrist.

If you're supposed to fill in the blanks, use the following list in order:

Top to Bottom (assuming 10–15 lines):

1. Distal phalanx
2. Middle phalanx
3. Proximal phalanx
4. Metacarpal V
5. Hamate
6. Capitate
7. Trapezium
8. Trapezoid
9. Scaphoid
10. Lunate
11. Triquetrum
12. Pisiform
13. Metacarpal I
14. Proximal phalanx of thumb
15. Distal phalanx of thumb
