Interpretation Introduction

Interpretation:

The two mechanisms by which neurotransmitters can exert its effects have to be given.

Concept Introduction:

Neurotransmitters: Neurotransmitters are chemicals that transmit messages from the nervous system to the target cell. They are the chemical messagers where the electrical signal from the nervous system is travelled from one neuron to another to reach the target cell.

Presynaptic neurons produces neurotransmitters which are stored in the small pockets of presynaptic neurons called vesicles from where the neurotransmitters are released according to the need. After neurotransmitter completes its job, it is immediately removed from the cleft of synapse for preparing the presynaptic neurons to get another impulse.

Neurotransmitters can exert its effects by either directly connecting with the hormone receptors or by relying on the second messengers.
