D. 24

Answer

To find the total number of phalanges in both limbs of a human, we can follow these steps:

1. **Identify the Structure of Phalanges**: Phalanges are the bones that make up the fingers of the hands and the toes of the feet. Each finger has three phalanges, while the thumb has two phalanges.

2. **Count the Phalanges in the Hands**:
- Each hand has 4 fingers and 1 thumb.
- Total fingers in both hands = 4 fingers/hand × 2 hands = 8 fingers.
- Total phalanges in fingers = 8 fingers × 3 phalanges/finger = 24 phalanges.
- Total phalanges in thumbs = 2 thumbs × 2 phalanges/thumb = 4 phalanges.
- Therefore, total phalanges in both hands = 24 (from fingers) + 4 (from thumbs) = 28 phalanges.

3. **Count the Phalanges in the Feet**:
- Each foot has 4 toes and 1 big toe.
- Total toes in both feet = 4 toes/foot × 2 feet = 8 toes.
- Total phalanges in toes = 8 toes × 3 phalanges/toe = 24 phalanges.
- Total phalanges in big toes = 2 big toes × 2 phalanges/big toe = 4 phalanges.
- Therefore, total phalanges in both feet = 24 (from toes) + 4 (from big toes) = 28 phalanges.

4. **Combine the Total Phalanges**:
- Total phalanges in both hands and both feet = 28 (from hands) + 28 (from feet) = 56 phalanges.

5. **Final Answer**: The total number of phalanges in both limbs of a human is 56.
