Mixed nerve and motor nerve

Explanation

### Step-by-Step Text Solution

1. **Definition of Mixed Nerve**: A mixed nerve is defined as a nerve that carries both sensory (afferent) and motor (efferent) fibers. This means it can transmit signals from sensory organs to the brain as well as carry commands from the brain to muscles.

2. **Example of Mixed Nerve**: The Glossopharyngeal nerve (Cranial Nerve IX) is an example of a mixed nerve. It is responsible for carrying sensory information related to taste (specifically bitter and sour) and motor information for swallowing.

3. **Effects of Damage to Mixed Nerve**: If the Glossopharyngeal nerve is damaged, it can lead to loss of taste sensations (bitter and sour) and impaired swallowing abilities.
