Sensory Neuron –
The sensory neuron is nerve cells within the nervous system responsible for converting external stimuli from the organism’s environment into internal electrical impulses.
Interneuron
The interneuron transmits impulses between other neurons.
Motor-neuron
This neuron carries signals from other parts of the body into the nervous system.
Neuron Structure – The structures of the Neuron cause the brain to properly function the way in which it does, each part with its own purpose.
How does an action potential move along the neuron fibre?
As an action potential travels down an axon there is a change in polarity across the membrane of the axon. The impulse travels down the axon in one direction only, to the axon terminal where it signals other neurons.
Neurons communicate in sending signals in what to do next.
Synapse
Above is the structure of the Synapse
The junction between the axis and the dendrites where that cause neurons to an electrical or chemical signal to another neuron. A neurotransmitter is released there. A chemical that allows one neuron to talk to the next neuron and continue sending the impulse.
- Information from one neuron flows to another neuron across a synapse. The synapse contains a small gap separating neurons
