What type of receptor is a dopaminergic receptor?
GPCR; cAMP 2nd messenger
Where are the dopaminergic receptors?

Nitric oxide (NO) Vasoactive intestinal peptide (VIP) Calcitonin Gene Related Peptide (CGRP) Neuropeptide Y (NPY) Substance P
What are the steps of neurotransmission?
- synthesis
- storage
- release (vesicle fuse with nerve terminal)
- action at receptor
- termination (reuptake, enzyme degradation, or diffusion)
