Sensory neurons, motor neurons, and interneurons. Motor neurons usually carry information to muscles and glands. Sensory neurons carry information from sense organs or free endings to the spinal cord or brain. Interneurons act as a go between.

Numerous nerve impulses arriving at a synapse at the same time exert a cumulative effect?
Kind of. Each neurone can have thousands of inputs from other neurones arriving at the same time. It all depends on the types of signal arriving from the other neurones. There are 2 types of incoming signal; 1. Excitatory Post-synaptic potentials (EPSPs) - These inputs depolarise the neurone (bring the negative voltage of the neurone closer to 0mV). 2.Inhibitory Post-synaptic potentials (IPSPs) - These inputs hyperpolarise the cell (make the neurone voltage more negative). Some of the inputs coming to the neurone will be EPSPs, some IPSPs. If all the inputs come in and there are more EPSPs then the neurone will depolarise. If the neurone depolarises to the firing threshold (around -40mV) then an action potential will be propagated and the neurone will transmit the message to the next neurone in the chain. If the majority of the inputs are IPSPs then the neurone will hyperpolarise and will not fire. If there are more EPSPs than IPSPs but the neurone still doesn't depolarise enough to reach the firing threshold then the neurone will not fire.
Is a neurone an organ or tissue?
neurone is a tissue
What do you call the neurone that connects the sensory and motor neurone together?
Interneurone or relay neurone
What are the type of nerve cells?
There are three different types of neurone: sensory, relay and motor - which are involved in a reflex arc.
How many major classes of neurons are there?
Sensury neurone, Motor Neurone
What does a Neurone cell do?
A neurone is a nerve cell, they allow you to feel pain.
What is a relay nerve cells?
Interneuron (relay neurone) Relays messages from sensory neurone to motor neurone. which make up the brain and spinal cord
Which type of neurone transmits the impulse from a motor to a sensory neurone?
No, not directly. Some sensory neurons can detect the effect of a motor neuron firing.
What is the name of the neurone that carries impulses to the central nervous system?
A sensory neurone.
What is the path that nervous impulse takes through the nervous system?
sensory neurone --> enters spinal cord --> relay neurone --> brain(is not a reflex action) or motor neurone(if action is reflex)
What is the name of a neuron that transmits neural impulse from the sensory neuron to the motor neuron?
A relay neurone passes impulses from a sensory neurone to a motor neurone.
What type of nerve cell is bipolar and unipolar?
they are mottor neurone nad sensory neurone
