1
What do sensory neuron do
carry electrical impulses from sense organ to CNS
2
What do inter neuron do
nerve cell found in CNS that connect with other neurons
3
What do motor neuron do
nerve cell, carry electrical impulse from CNS to muscle and glands (effectors), this can be rapid action or slow response
4
What are neurons
specialised cells that carry electrical impulse. they have a synapse between them
5
what is a neurotransmitter
chemicals which transfer a chemical message of the impulse across the synapse or from neuron to effector organ
6
what are the steps of neurotransmitter diffusing over a synapse
1) electrical only travels in one direction (cell body to axon terminal)
2) electrical impulse trigger nerve endings to release neurotransmitter
3) neurotransmitter diffuse over synapse
4) neurotransmitter binds with receptor molecules or next neuron and stimulates it to transmit the electrical impulse
