Summary Introduction

To discuss:

The role of neurotransmitter in synaptic transmission.

Introduction:

Neurotransmitters are released by exocytosis that binds to specific receptors of the receiving cell. Some of the neurotransmitters are inhibitory, some are excitatory, and for others, the end product depends on the type of receptor the postsynaptic cell has. The norepinephrine (NE) is involved in waking, dreaming, and mood changing. The common function of NE is to mobilize the body and brain for action. Acetylcholine and norepinephrine have both the excitatory and inhibitory effect based on the type of receptor availability. Acetylcholine exhibits skeletal muscles, but has an inhibitory effect on cardiac muscles.
