Which one of the following does not act as a neurotransmitter?

Correct answer: A. Cortisone

  • A. Cortisone
  • B. Acetylcholine
  • C. Epinephrine
  • D. Norepinephrine

Explanation

Neurotransmitters are chemicals that are used to relay, amplify and modulate electrical signals between a neuron and another cell. Substances that act as neurotransmitters can be categorized into three major groups: (1) amino acids (primarily glutamic acid, GABA, aspartic acid and glycine), (2) peptides (vasopressin, somatostatin, neurotensin, etc.), and (3) monoamines (norepinephrine, dopamine and serotonin) plus acetylcholine. Cortisone is a glucocorticoid steroid hormone, produced by the adrenal glands and has anti-inflammatory and immune system suppressing properties.

About Coordination and Control

Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
