Lateral funiculi have ........... type of nerve fibres

Options

A. sensory
B. motor
C. both (1) and (2)
D. none of these

Answer

To answer the question "Lateral funiculi have ........... type of nerve fibres," we need to analyze the structure and function of the lateral funiculi in the spinal cord. Here’s a step-by-step solution:

### Step 1: Understand the Structure
- The lateral funiculi are part of the spinal cord's white matter. The spinal cord consists of two types of matter: gray matter and white matter.

### Step 2: Identify the Composition of Lateral Funiculi
- The lateral funiculi contain myelinated nerve fibers. Myelinated fibers are essential for faster transmission of nerve impulses.

### Step 3: Determine the Type of Nerve Fibers
- The question asks for the type of nerve fibers present in the lateral funiculi. It is important to note that these fibers do not specifically categorize as sensory or motor fibers.

### Step 4: Analyze the Options
- The options provided are:
1. Sensory
2. Motor
3. Both sensory and motor
4. None of these

### Step 5: Conclusion
- Since the lateral funiculi contain myelinated nerve fibers but do not exclusively consist of sensory or motor fibers, the correct answer is "none of these."

### Final Answer:
- Lateral funiculi have **none of these** types of nerve fibers.
