Explanation:

difference between Sensory and Motor Neurons?

• Sensory neurons bring sensory impulse from sensory organs to the central nervous system, whereas motor neurons carry motor impulses from the central nervous system to specific effectors.

• Sensory neurons are situated in the dorsal root ganglion of the spinal nerve, whereas motor neurons are situated in the ventral root ganglion of the spinal cord.

• Sensory neurons follow afferent pathways while motor neurons follow efferent pathways.

• An average adult has about 10 million sensory neurons and half a million of motor neurons.

• Motor neurons are multipolar, and sensory neurons are unipolar.

• Sensory neuron has afferent fiber, whereas motor neuron has efferent fiber.

• Motor neurons do not generate commands to communicate with muscles, but receive from sensory neurons.
