Options

A. 23333
B. 33333
C. 33322
D. 32333

Answer

To determine the phalangeal formula for the human hand, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of the Hand**:
- The human hand consists of several bones, including the humerus (upper arm), radius, ulna (forearm), carpals (wrist), metacarpals (palm), and phalanges (fingers).

2. **Count the Phalanges**:
- The hand has a total of 5 digits (fingers), which includes the thumb and four other fingers.
- The thumb has **2 phalanges** (proximal and distal).
- Each of the other four fingers has **3 phalanges** (proximal, middle, and distal).

3. **Write the Phalangeal Formula**:
- The formula for the phalanges can be expressed by counting the number of phalanges in each digit:
- Thumb: 2
- Index Finger: 3
- Middle Finger: 3
- Ring Finger: 3
- Little Finger: 3
- Therefore, the phalangeal formula is written as: **2, 3, 3, 3, 3**.

4. **Conclusion**:
- The phalangeal formula for the hand is **2, 3, 3, 3, 3**.

### Final Answer:
The phalangeal formula for the hand is **2, 3, 3, 3, 3**.
