Each forelimb consist of _____bones

Answer

To answer the question "Each forelimb consists of _____ bones," we can break down the components of the forelimb and count the bones in each part.

### Step-by-Step Solution:

1. **Identify the Parts of the Forelimb**: The forelimb can be divided into several parts: the upper arm, forearm, wrist (carpals), hand (metacarpals), and fingers (phalanges).

2. **Count the Bones in Each Part**:
- **Upper Arm**: There is 1 bone in the upper arm, known as the humerus.
- **Forearm**: The forearm consists of 2 bones: the radius and the ulna.
- **Wrist (Carpals)**: There are 8 carpal bones in the wrist.
- **Hand (Metacarpals)**: There are 5 metacarpal bones in the hand.
- **Fingers (Phalanges)**: Each finger has 3 phalanges (except for the thumb, which has 2). Therefore, for 4 fingers, the total is 4 x 3 = 12 phalanges, plus 2 for the thumb, totaling 14 phalanges.

3. **Total Count of Bones**:
- Upper Arm: 1 (humerus)
- Forearm: 2 (radius + ulna)
- Carpals: 8
- Metacarpals: 5
- Phalanges: 14 (12 + 2)

Now, we add them up:
- Total = 1 (humerus) + 2 (radius + ulna) + 8 (carpals) + 5 (metacarpals) + 14 (phalanges) = 30 bones.

4. **Final Answer**: Each forelimb consists of **30 bones**.
