The junction between a motor neuron and the sarcolemma of the muscle fibre is called the 

Options

A. Neuro muscular junction
B. Moter end plate
C. Gap junction
D. Both 1 and 2

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the junction between a motor neuron and the sarcolemma of a muscle fiber.

2. **Identifying Key Terms**:
- Motor neuron: A type of neuron that transmits impulses to muscles.
- Sarcolemma: The cell membrane of a muscle fiber.
- Junction: The area where two structures meet.

3. **Options Analysis**: The options provided are:
- A) Neuromuscular junction
- B) Motor end plate
- C) Gap junction
- D) Both A and B

4. **Defining the Junction**: The junction between a motor neuron and the sarcolemma is known as the **neuromuscular junction**. This is where the motor neuron communicates with the muscle fiber.

5. **Alternative Name**: The neuromuscular junction is also referred to as the **motor end plate**. Thus, both terms refer to the same structure.

6. **Conclusion**: Since both options A (neuromuscular junction) and B (motor end plate) are correct, the final answer is **D) Both A and B**.
