The Relay Neurone
There is no specific type of neuron that transmits impulses directly from a motor neuron to a sensory neuron. Motor neurons transmit signals from the central nervous system to muscles or glands, while sensory neurons transmit signals from sensory receptors to the central nervous system for processing. Communication between motor and sensory pathways typically involves interneurons within the central nervous system.

In a simple reflex arc, there are typically three neurons and two synapses. The sensory neuron carries the signal from the receptor to the central nervous system, where it synapses with the interneuron. The interneuron then synapses with the motor neuron, which carries the signal to the effector organ to produce a response.
In humans, one function of an interneuron is to relay impulses directly from sensory neurons to motor neurons. This allows for a quick response without involving the brain in every reflex action.
Functionally, neurons come in three varieties; motor neurons, sensory neurons and interneurons. Motor neurons conduct motor impulses from the CNS to the muscles. Sensory neurons conduct motor impulses from the rest of the body to the CNS. Interneurons connect the sensory to the motor so we can respond to incoming sensory stimuli.
The sensory or afferent division of the peripheral nervous system transmits impulses from the sense organs to the CNS.

A relay neurone passes impulses from a sensory neurone to a motor neurone.
Sensory neurons have their cell bodies in the dorsal ganglion at the one or two segemental levels from the dendrite entry. They make a synapse onto interneurons in spinal cord. Motor neurons have their cell bodies in the spinal cord.
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.

Sensory Neurons
Sensory nerves carry impulses to the brain (as sights seen, sounds heard, etc.). Motor nerves carry impulses from the brain to cause the body to do things such as move muscles.
Sensory Neurons
vagus nerve
Optic nerve
The ascending tracts carry information to the brain.
