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 "Select the incorrect statement," we will analyze each statement one by one to determine which one is incorrect.

### Step 1: Analyze the first statement
**Statement 1:** "Bipolar neuron has only one dendrite."
- **Analysis:** Bipolar neurons are characterized by having one axon and one dendrite. Therefore, this statement is correct.

### Step 2: Analyze the second statement
**Statement 2:** "Pia mater is in contact with the brain."
- **Analysis:** The pia mater is the innermost layer of the meninges that directly covers the surface of the brain. This statement is also correct.

### Step 3: Analyze the third statement
**Statement 3:** "Afferent fibers carry impulses from the central nervous system to the peripheral tissue."
- **Analysis:** This statement is incorrect. Afferent fibers carry sensory impulses from the peripheral tissues to the central nervous system, while efferent fibers carry impulses from the central nervous system to the peripheral tissues (such as muscles and glands).

### Step 4: Analyze the fourth statement
**Statement 4:** "Cranular bodies are found in the dendrites of neuron."
- **Analysis:** Granular bodies, also known as Nissl bodies, are found in the cell body of neurons and not specifically in the dendrites. However, this statement is somewhat misleading but not outright incorrect, as Nissl bodies can be present in dendrites to some extent.

### Conclusion
After analyzing all the statements, the incorrect statement is:
**Option 3:** "Afferent fibers carry impulses from the central nervous system to the peripheral tissue."

### Final Answer
The incorrect statement is: **Option 3.**
