Afferent nerve fibre carries impulses from

Options

A. effector to central neural system
B. receptor to central neural system
C. central neural system to muscle
D. central neural system to receptors.

Explanation

### Step-by-Step Solution:

1. **Understanding Afferent Nerve Fibers**:
- Afferent nerve fibers are responsible for transmitting sensory information from the body to the central nervous system (CNS).

2. **Differentiating Between Afferent and Efferent Fibers**:
- Afferent fibers (also known as sensory neurons) carry impulses from peripheral organs (like receptors) to the CNS.
- Efferent fibers (or motor neurons) carry impulses from the CNS to the peripheral organs.

3. **Identifying the Direction of Impulse Transmission**:
- The question specifically asks about the direction of impulses carried by afferent nerve fibers.
- Afferent fibers bring sensory information from the peripheral receptors (like skin, eyes, ears) to the CNS for processing.

4. **Conclusion**:
- Therefore, the afferent nerve fibers carry impulses from receptors (located in peripheral organs) to the central nervous system.

5. **Final Answer**:
- Afferent nerve fibers carry impulses from receptors to the central nervous system.
