What Are The Major Steps Of The Neural Transmission System?

The neural transmission system is characterized by a process of cognitive nature that contains chemical connections between its components rather than physical connections inside the human body. Altogether there are four steps on the basis of which the neural transmission system functions. In the first step the production of neurotransmitters (chemicals responsible for carrying messages) takes place, which are later on stored in the axon.

Following the first step is the second step, in which if there is a case of an action potential arrival, the axon tends to release neurotransmitters that were produced in the first step. The next step, which is the third step is carried on only if there is a case of an action potential arrival. In this step, the neurotransmitters are carried across the synapse (a connection of chemical nature that ends the gap between two separate neurons) to receptor sites that are present on the dendrites on another neuron. Once a neurotransmitter finds its fit in a receptor site, the delivery of a excitatory or inhibitory message takes place. If the number of excitatory messages is adequate enough, the neuron will fire.
