The principle of impulse delivery:
It is necessary to know in advance that impulses are a form of stimulation that is channeled through neuron cells from the outside environment.
There are two principles of impulse delivery, namely through neurons and through synapses.
1.Delivery of impulses through neurons:
The delivery of impulses in this way occurs because there is a difference in the electrical charge between the outside and the inner membrane of nerve cell fibers.
when it receives stimuli in the form of impulses, the outer surface of the nerve fibers is negatively charged and the inner surface is positively charged. this condition is called depolarization.
then there will be electricity from the negative area to the positive area. the impulse will then be forwarded to the neuron and eventually towards the spinal cord and brain.
impulses will be processed by the brain and spinal cord and eventually a response will be formed and forwarded to motor neurons until action is formed.
2. Delivery of impulses through synapses:
Impulse delivery in this way involves a presynaptic membrane, where if the impulse has arrived at the presynaptic membrane, the vesicles will release neurotransmitter substances.
this substance serves to deliver impulses to the dendrite end of the next neuron. the neurotransmitter will receive an impulse and will diffuse through the synaptic gap.
then it will bind to a special protein in the post-capsule membrane. This bond between neurotransmitters and receptors can cause impulses to be transmitted to other nerves that are interconnected.
