Afferent nerves are called _________, and motor nerves are called __________.

Options

A. peripheral nerves , cranial nerves
B. sensory nerves , efferent nerves
C. cranial nerves , peripheral nerves
D. motor nerves , sensory nerves

Answer

To answer the question, "Afferent nerves are called _________, and motor nerves are called __________," we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding Afferent Nerves**:
- Afferent nerves are responsible for carrying sensory information from the sensory receptors to the central nervous system (CNS). They transmit signals related to sensations such as touch, pain, temperature, and other stimuli.

2. **Identifying the Correct Term for Afferent Nerves**:
- Afferent nerves are also known as **sensory nerves** because they carry sensory information to the brain.

3. **Understanding Motor Nerves**:
- Motor nerves, on the other hand, are responsible for transmitting impulses from the CNS to the muscles or glands, facilitating movement or secretion.

4. **Identifying the Correct Term for Motor Nerves**:
- Motor nerves are also referred to as **efferent nerves** because they carry signals away from the CNS to effectors (muscles or glands).

5. **Final Answer**:
- Therefore, the complete answer is: Afferent nerves are called **sensory nerves**, and motor nerves are called **efferent nerves**.

### Final Answer:
Afferent nerves are called **sensory nerves**, and motor nerves are called **efferent nerves**.
