A nerve is a bundle of neurones
There are very few.Some neurones are upto 3m long.
sensory neurones motor neurones
There are lots of branches of science, including biology, chemistry, and physics.
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
sensory and motor neurons are sometimes very long so that the impulses can be carried away from the body very quickly. in the motor neuron the impulses "jump" over the fatty tissue to the Node Of Ranvier.
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
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.
