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.

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.
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.
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
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.
Is neurone a tissue?
no...
Are there any diseases or disorders that affect the diaphragm?
diaphragm cancer, motor neurone diaphragm cancer, motor neurone
Is a neurone an organ or tissue?
A neuron is a type of cell, not an organ or tissue. Neurons are the basic building blocks of the nervous system and work together to transmit electrical and chemical signals in the body.
Motor neurone disease is infective?
Motor neurone disease is not an infectious disease. It is a progressive neurological condition that affects the nerves in the brain and spinal cord that control movement. The exact cause of motor neurone disease is not fully understood.
Is neurone a tissue a organ or a cell?
it is a cell
What do you call the neurone that connects the sensory and motor neurone together?
The neuron that connects the sensory and motor neurons together is called an interneuron. Interneurons facilitate communication between sensory and motor neurons within the central nervous system.
How does the passage of a touch signal pass from skin to the cerebral cortex?
Pressure receptors in the skin pick up the stimulus. It passes along a sensory neurone to the central nervous system. Within the CNS it is transferred to the cerebral contex via an association neurone, relay neurone.
