Drug Action On Gut Motility Biology Essay.
A cholinergic drug that worked the same as acetylcholine would You correctly answered: c. be an agonist and decrease heart rate. 3. 3. Norepinephrine affects the heart rate by You correctly answered: a. increasing the rate of depolarization and increasing the frequency of action.
In the motor system, in pathways where both dopamine and acetylcholine are present (for example, in the basal ganglia), dopamine acts as a regulator for acetylcholine release. When dopamine is suppressed, as is the case with some antipsychotic compounds, acetylcholine levels rise dramatically and motor rigidity, spasms, restlessness, drooling, tremor, and shuffling become evident.
There, acetylcholine opens receptors on the muscle cells, triggering the process of contraction. Of course, once the message is passed, the neurotransmitter must be destroyed, otherwise later signals would get mixed up in a jumble of obsolete neurotransmitter molecules. The cleanup of old acetylcholine is the job of acetylcholinesterase.

Acetylcholine is actylcholine is an ester of acetic acid and choline, which acts as a neurotransmitter.It has a role as a vasodilator agent, a muscarinic agonist, a hormone, a human metabolite, a mouse metabolite and a neurotransmitter.
Several studies have been undertaken to demonstrate the effects of neurotransmission on human behaviour. Outline and state which neurotransmitters will be explained; Serotonin and acetylcholine will be explained in the following essay. Body Neurotransmitter 1: Serotonin. Introduce serotonin.
Acetylcholine was the first neurotransmitter discovered back in the early 1900’s. You are probably well aware of how important the acetylcholine neurotransmitter is. It was originally described as “vagus stuff” by Otto Loewi simply because it was so important to so many mental and emotional actions.(1). A neurotransmitter is a chemical messenger that allows our neurons to communicate.
