Answer

To determine the number of phalanges in the index finger, follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Hand**:
- The human hand consists of several bones, including the wrist bones (carpals), metacarpals, and phalanges.

2. **Identify the Types of Bones**:
- The wrist has 8 carpal bones.
- There are 5 metacarpal bones in the palm.
- The fingers are made up of phalanges.

3. **Differentiate Between the Fingers**:
- The thumb has 2 phalanges: proximal and distal.
- The other fingers, including the index finger, have 3 phalanges: proximal, middle, and distal.

4. **Focus on the Index Finger**:
- Since the question specifically asks about the index finger, we need to note that it is one of the four fingers (excluding the thumb) that each have 3 phalanges.

5. **Conclude the Answer**:
- Therefore, the number of phalanges in the index finger is **3**.

### Final Answer:
The number of phalanges in the index finger is **3**.
