Answer

To determine the total number of podomeres in the leg of a cockroach, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Cockroach**:
- The cockroach belongs to the phylum Arthropoda and the class Insecta. Insects typically have three pairs of jointed appendages.

2. **Identify the Body Segments**:
- The body of a cockroach is divided into three main parts: the head, thorax, and abdomen. The legs are attached to the thorax.

3. **Examine the Thorax**:
- The thorax is divided into three segments. Each segment gives rise to one pair of legs.

4. **Identify the Leg Segments (Podomeres)**:
- The leg of a cockroach consists of five distinct segments, known as podomeres.

5. **List the Podomeres**:
- The five podomeres in the leg of a cockroach are:
- **Coxa**: The segment that connects the leg to the thorax.
- **Trochanter**: The segment between the coxa and the femur.
- **Femur**: The segment that is typically thicker and contains sensory bristles.
- **Tibia**: The long bone-like segment that follows the femur.
- **Tarsus**: The final segment, which is further divided into smaller parts, including the plantula and the claw.

6. **Conclusion**:
- Therefore, the total number of podomeres in the leg of a cockroach is **5**.

### Final Answer:
The total number of podomeres in the leg of a cockroach is **5**.
