Chapter 48, Problem 48.4CR
Summary Introduction
To review: Why the drugs used in nervous system diseases are targeted against receptors rather than neurotransmitters.
Introduction:
Neurotransmitters or chemical messengers are the molecules that are available for the transmission of impulses from one neuron to another neuron, a muscle or a gland. It is released from the pre-synaptic cell and acts on the receptors that are present in the post-synaptic cell.
