A spinal nerve is a __________ nerve while the olfactory nerve is a ___________nerve

Answer

To answer the question, we need to identify the types of nerves associated with the spinal nerve and the olfactory nerve.

1. **Identify the spinal nerve**:
- Spinal nerves are classified as mixed nerves. This means they contain both sensory and motor fibers.
- Sensory fibers carry information from the body to the central nervous system (CNS), while motor fibers transmit commands from the CNS to the muscles.

2. **Identify the olfactory nerve**:
- The olfactory nerve is classified as a sensory nerve.
- It is one of the cranial nerves (specifically, cranial nerve I) and is responsible for the sense of smell. It contains sensory nerve fibers that send information about odors to the brain.

3. **Fill in the blanks**:
- Therefore, the complete statement is: "A spinal nerve is a **mixed** nerve while the olfactory nerve is a **sensory** nerve."

Final Answer: A spinal nerve is a **mixed** nerve while the olfactory nerve is a **sensory** nerve.
