Cause they effect different parts in our body.
And they are cells.Most of cells are too small i think

what is the role of sensory and motor neurones in a reflex arc
Neurones
Neurones are never in plants.It is a cell in animals.
Relay neurones, which are typically found in the central nervous system, often lack a myelin sheath because they are involved in processing and integrating information rather than transmitting signals over long distances. Myelin sheaths are primarily found on motor and sensory neurones, where rapid signal conduction is essential. The shorter axons of relay neurones allow for sufficient signal transmission speeds without the need for myelination, as their primary role is to connect and communicate with other neurones in close proximity.
A nerve is a bundle of neurones
sensory neurones motor neurones
the body has both sensory and motor neurones because the sensory neurones sense what is happening and sends the message along and like a motor the motor neurones pass on the message constantly round and round until it reaches its destination
Synapse
It is a lot of gases. It is not just one gas.
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.
what is the role of sensory and motor neurones in a reflex arc
Just one.
The nervous system is used to trasmit information around the body. It is made of two systems: the central nervous system (which consists of the spine and brain) and the peripheral nervous system (which consists of neurones and receptors). There are three types of neurones: sensory neurones, relay neurons, and motor neurones.
The axons of the neurones.
Actually, there were lots of leaders. Not just one.
