Since I can't view or access images directly, I can’t see the specific labels or structure of the diagram you’re referring to. However, based on the title "Bones of the Hand" and the typical layout of such diagrams in anatomy and physiology worksheets, I can help you identify and label the bones of the hand.
Here’s a breakdown of the major bones in the hand and their typical positions:
---
Bones of the Hand:
1.
Carpal Bones (8 small bones in the wrist):
- Located at the base of the hand, near the wrist.
- Arranged in two rows:
-
Proximal row (closer to the forearm):
1.
Scaphoid
2.
Lunate
3.
Triquetrum
4.
Pisiform (a small sesamoid bone on the palmar side)
-
Distal row (closer to the hand):
5.
Trapezium
6.
Trapezoid
7.
Capitate
8.
Hamate
2.
Metacarpal Bones (5 bones in the palm):
- Connect the carpal bones to the fingers.
- Numbered from 1 (thumb) to 5 (little finger).
- Each metacarpal has a base (near the carpus), shaft, and head (articulates with phalanges).
3.
Phalanges (14 bones in the fingers):
- Each finger has three phalanges:
proximal,
middle (intermediate), and
distal.
- The thumb has only two:
proximal and
distal.

Typical Labeling Order in Diagrams:
From top to bottom or left to right, depending on how the diagram is drawn:
-
Top row (wrist area):
- Scaphoid
- Lunate
- Triquetrum
- Pisiform
-
Second row (wrist area):
- Trapezium
- Trapezoid
- Capitate
- Hamate
-
Middle section (palm):
- Metacarpals (labeled as Metacarpal I to V)
-
Fingers:
- Proximal phalanx
- Middle phalanx
- Distal phalanx
- (Thumb: Proximal and distal phalanges)

How to Fill in the Blanks:
Assuming the diagram shows the hand with labeled lines pointing to different bones:
1.
Start with the wrist bones (carpals): Identify the proximal and distal rows.
2.
Move to the metacarpals: These are the long bones in the palm.
3.
Then the fingers: Label each segment of the fingers.

Example Labels (if the diagram follows standard layout):
- Top-left:
Scaphoid
- Top-right:
Pisiform
- Below scaphoid:
Trapezium
- Below pisiform:
Hamate
- Middle of wrist:
Lunate,
Triquetrum,
Capitate,
Trapezoid
- Palm:
Metacarpal I (thumb) to
Metacarpal V (little finger)
- Fingers:
Proximal phalanx,
Middle phalanx,
Distal phalanx

If you can describe the position of the blank boxes or list which parts are pointed to, I can give you exact labels for each box. Otherwise, use this guide to fill in the worksheet accurately!
Parent Tip: Review the logic above to help your child master the concept of anatomy and physiology worksheets.
