Want this question answered?
A nerve is a bundle of neurones
Cause they effect different parts in our body. And they are cells.Most of cells are too small i think
Sensory 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.
what is the role of sensory and motor neurones in a reflex arc
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.
Yes, nerves have lots of connecting side branches! Hope I helped!
