Select the incorrect statement.

Options

A. Bipolar neuron has only one dendrite.
B. Piamater is in contact with brain .
C. Afferent fibres carry impulses from CNS to peripheral tissues .
D. Granular bodies are found in dendrites of neuron .

Answer

To solve the question of selecting the incorrect statement, we will analyze each of the provided options one by one.

### Step-by-Step Solution:

1. **Analyze the first statement: "Bipolar neuron has only one dendrite."**
- A bipolar neuron is characterized by having two extensions: one axon and one dendrite. Therefore, this statement is **incorrect** because a bipolar neuron does not have only one dendrite; it has one axon and one dendrite.

2. **Analyze the second statement: "Pia mater is in contact with the brain."**
- The pia mater is indeed the innermost layer of the meninges that directly covers the brain and spinal cord. This statement is **correct**.

3. **Analyze the third statement: "Afferent fibers carry impulses from the central nervous system to peripheral tissues."**
- This statement is **incorrect**. Afferent fibers actually carry impulses from sensory receptors to the central nervous system, while efferent fibers carry impulses from the central nervous system to peripheral tissues.

4. **Analyze the fourth statement: "Granular bodies are found in dendrites of neuron."**
- Granular bodies, also known as Nissl bodies, are indeed found in the cell bodies (soma) of neurons and can also be present in dendrites. This statement is **correct**.

### Conclusion:
The incorrect statements are:
- "Bipolar neuron has only one dendrite."
- "Afferent fibers carry impulses from the central nervous system to peripheral tissues."

However, since the question asks for a single incorrect statement, the most clearly incorrect statement is the first one regarding the bipolar neuron.

### Final Answer:
The incorrect statement is: **"Bipolar neuron has only one dendrite."**
