I'll help you identify the bones of the hand in this anatomy worksheet. Let me work through this systematically by identifying each bone from top to bottom and left to right.
The hand consists of three main groups of bones:
1.
Carpals (wrist bones) - 8 bones arranged in two rows
2.
Metacarpals (palm bones) - 5 bones
3.
Phalanges (finger bones) - 14 bones total
Let me identify each labeled structure:
Top section (proximal row of carpals, lateral to medial):
- First label (lateral side): Scaphoid
- Second label: Lunate
- Third label: Triquetrum
- Fourth label (medial side): Pisiform
Middle section (distal row of carpals, lateral to medial):
- Fifth label (lateral side): Trapezium
- Sixth label: Trapezoid
- Seventh label: Capitate
- Eighth label (medial side): Hamate
Lower section (metacarpals and phalanges):
- Ninth label: Metacarpals (the five palm bones)
- Tenth label: Proximal phalanges (first segment of fingers)
- Eleventh label: Middle phalanges (second segment - absent in thumb)
- Twelfth label: Distal phalanges (fingertip bones)
Wait, let me reconsider based on the diagram layout more carefully:
Looking at the pointing lines:
- Top left labels point to proximal carpal row
- Top right labels point to distal carpal row
- Middle labels point to metacarpals
- Bottom labels point to phalanges
Let me be more precise with the specific bones being pointed to:
Proximal carpal row (from lateral/thumb side to medial/pinky side):
1. Scaphoid
2. Lunate
3. Triquetrum
4. Pisiform
Distal carpal row (from lateral to medial):
5. Trapezium
6. Trapezoid
7. Capitate
8. Hamate
Metacarpals:
9. Metacarpal bones (I-V)
Phalanges:
10. Proximal phalanx
11. Middle phalanx
12. Distal phalanx
Final Answer:
Left side (top to bottom):
1. Scaphoid
2. Lunate
3. Triquetrum
4. Pisiform
5. Metacarpals
6. Proximal phalanx
Right side (top to bottom):
1. Trapezium
2. Trapezoid
3. Capitate
4. Hamate
5. Middle phalanx
6. Distal phalanx
