Neurons are the structural and functional unit of the nervous system. They constitute the communication network of the nervous system and transfer electrical impulses between the central nervous system and sensory organs. They are three types of neurons based on the function as follows:
- Sensory Neuron
- Motor Neuron
- Inter-Neuron
Here, in this article let us discuss the difference between sensory and motor neurons.
Sensory vs Motor Neurons
| Sensory Neuron | Motor Neuron |
| Neurons that carry sensory impulse from sensory organs to the central nervous system are known as sensory neurons | A neuron that carries motor impulses from the central nervous system to specific effectors is known as motor neurons. |
| They are located in the dorsal root ganglion of the spinal nerve | They are located in the ventral root ganglion of the spinal cord. |
| It is unipolar | It is multipolar |
| Comprises of a short axon | Comprises of a long axon |
| An adult has an average of 10 million sensory nerves in the body | Half million of motor neurons are found in the body |
| Found in eyes, skin, ears, tongue and nose | Found in muscles and glands |
The main difference between sensory and motor neuron is their function and structure. Both these neurons enable the central nervous system to coordinate different functions in the body.
