What is the main function of a connecting neuron?
To take the signal from the sensory neurons to the motor neurons or other integrative neurons
A is for what part of the neurone that carries impulses away from the cell body?
A is for the axon, which is a long, thin extension of a neuron that carries impulses away from the cell body towards other neurons or target cells.
How many major classes of neurons are there?
Sensury neurone, Motor Neurone
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 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 is the name of the neurone that carries impulses to the central nervous system?
A sensory neurone.
What carries impulses away from neuron cell bodies?
The axon of the neurone carries the impulse away from the cell body. The axon of the neurone carries the impulse away from the cell body.
What is the main function of a connecting neuron?
To take the signal from the sensory neurons to the motor neurons or other integrative neurons
Is a neurone an organ or tissue?
neurone is a tissue
A is for what part of the neurone that carries impulses away from the cell body?
A is for the axon, which is a long, thin extension of a neuron that carries impulses away from the cell body towards other neurons or target cells.
What do you call the neurone that connects the sensory and motor neurone together?
Interneurone or relay neurone
What is a motor neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
What does a Neurone cell do?
A neurone is a nerve cell, they allow you to feel pain.
How many major classes of neurons are there?
Sensury neurone, Motor Neurone
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.
