Question

In the context of neurotransmitters, which of the following best describes the effect of norepinephrine stimulation?

Answer 1

Answer : It helps to control the levels of alertness.

Explanation : Neurotransmitters are endogenous chemicals which enables neuro-transmission. It is a type of a chemical messenger which allows to transmit signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell. It helps to maintain the level of alertness in the body by maintaining the chemical synapse when required.

Answer 2

Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as a hormone and neurotransmitter. The name "noradrenaline," derived from Latin roots meaning "at/alongside the kidneys," is more commonly used in the United Kingdom; in the United States, "norepinephrine," derived from Greek roots having that same meaning, is usually preferred. "Norepinephrine" is also the international nonproprietary name given to the drug.Regardless of which name is used for the substance itself, parts of the body that produce or are affected by it are referred to as noradrenergic.
