The interneurons are located in the

Options

A. Sensory receptors
B. Spinal cord
C. Efferent pathway
D. Effectors

Answer

**Step-by-Step Solution:**

1. **Understanding Neurons**: Begin by recognizing that neurons are the fundamental units of the nervous system responsible for transmitting nerve impulses. They can be classified into three main categories based on the direction of impulse transmission.

2. **Categories of Neurons**:
- **Sensory Neurons**: Also known as afferent neurons, these carry nerve impulses towards the central nervous system (CNS), which includes the brain and spinal cord.
- **Interneurons**: These are also referred to as relay neurons and are located within the CNS. They serve as a link between sensory and motor neurons.
- **Motor Neurons**: Known as efferent neurons, these carry nerve impulses away from the CNS to effectors, such as muscles or glands.

3. **Locating Interneurons**: Since interneurons are defined as neurons that connect sensory and motor neurons and are found in the central nervous system, we need to identify where in the CNS they are located.

4. **Identifying the Correct Answer**: The options provided are:
- Sensory receptors
- Spinal cord
- Efferent pathway
- Effectors

Among these, the spinal cord is a part of the central nervous system where interneurons are located. Therefore, the correct answer to the question is the spinal cord.

5. **Conclusion**: The interneurons are located in the spinal cord, which is part of the central nervous system.

**Final Answer**: The interneurons are located in the spinal cord.
