Chapter 15, Problem 9TYR
Summary Introduction
Introduction:
Neurotransmitters are the chemical messengers that are released by the neurosecretory cells and trigger the signal cascade mechanism to transmit impulses to the target organs. Acetylcholine is a key neurotransmitter secreted by the preganglionic nerve fibers.
