PPT-Cholinergic Neurotransmission

Dr Nirbhay Kumar Asstt Professor amp Head Deptt of Veterinary Pharmacology amp Toxicology Bihar Veterinary College Bihar Animal Sciences University Patna Cholinergic Transmission. The process of neurotransmission is described in detail This module provides a key foundation for the next 57375ve modules which will discuss the impact of speci57375c drugs on the body and the brain Learning Objectives At the end of this module Stu Define cholinergic Drugs ?.

JOYCE K. ONO’ AND PAUL M. SALVATERRA Division of Neurosciences, City of Hope Research Institute, Duarte, California 91010 Abstract The effects of a-toxins from Bungarus multicinctus M rever ACH is synthesized in the cholinergic neurons from choline and acetyl CoA then stored in synaptic vesicles then it will be release into synaptic gap to bind post synaptic receptors and lead to biological response..
