INTRODUCTION
 Nerve transmission is the process of communication between cells which are
used for the process of sending signals from one cell to another (Seyedabadi
et al. 2014)
 The main components of neurotransmission are the neurotransmitters which
are the chemicals involved in the transmission of nerve impulses.
 Proper stimulation of an electric signal triggers the release of the
neurotransmitters from the vesicles which then act as chemical messengers.
 Example of neurotransmitters: dopamine, serotonin (Baldinger et al. 2014).

THE PROCESS OF NERVE TRANSMISSION

• The process of
neurotransmission takes place in
various steps.
• Depolarization of the membrane
after the action potential reaches
the axon terminal.
• Opening of voltage gated
calcium channels and inflow of
Calcium.
• Influx of calcium ions in the
synaptic vesicles for the release
of neurotransmitters.
• Binding of the neurotransmitter
