Answer

To determine the number of spinal nerves in a frog, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Nervous System**:
- The nervous system of frogs consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS includes cranial nerves and spinal nerves.

2. **Identify the Number of Spinal Nerves**:
- Frogs have a specific number of spinal nerves that emerge from the spinal cord.

3. **Compare with Other Species**:
- For context, humans have 30 pairs of spinal nerves, while frogs have a different count.

4. **Determine the Correct Count**:
- It is established that frogs have 10 pairs of spinal nerves. These nerves are responsible for transmitting signals between the spinal cord and various parts of the frog's body.

5. **Final Answer**:
- Therefore, the number of spinal nerves in a frog is **10 pairs**.
