Muscles, glands (effectors) receive motor impulses from CNS through  

Options

A. motor neuron
B. sensory neuron
C. inter neuron
D. all the above

Answer

To solve the question "Muscles, glands (effectors) receive motor impulses from CNS through," we need to analyze the roles of different types of neurons in the nervous system. Here’s a step-by-step breakdown:

### Step 1: Understand the Central Nervous System (CNS)
The Central Nervous System (CNS) consists of the brain and spinal cord. It is responsible for processing sensory information and coordinating responses.

**Hint:** Remember that the CNS is the control center of the body.

### Step 2: Identify the Types of Neurons
There are three main types of neurons involved in transmitting impulses:
1. **Sensory Neurons**: These carry impulses from sensory organs (like skin, eyes, ears) to the CNS.
2. **Motor Neurons**: These transmit impulses from the CNS to effectors (muscles and glands).
3. **Interneurons**: These connect sensory neurons to motor neurons within the CNS.

**Hint:** Think of sensory neurons as the messengers bringing information to the CNS, while motor neurons send commands out.

### Step 3: Determine the Role of Motor Neurons
Motor neurons are specifically responsible for conveying motor impulses from the CNS to effectors, which include muscles and glands. This is the direct pathway for executing responses such as movement or secretion.

**Hint:** Focus on the function of motor neurons in relaying commands from the CNS to effectors.

### Step 4: Evaluate the Options
Now, let's evaluate the options given in the question:
- **Motor Neurons**: Correct, as they carry impulses from the CNS to effectors.
- **Sensory Neurons**: Incorrect, as they carry impulses to the CNS, not from it.
- **Interneurons**: Incorrect, as they connect sensory and motor neurons but do not directly send impulses to effectors.
- **All of the Above**: Incorrect, since only motor neurons are responsible for sending impulses to effectors.

**Hint:** Only one type of neuron is responsible for sending impulses to muscles and glands.

### Final Answer
Muscles and glands (effectors) receive motor impulses from the CNS through **motor neurons**.
