Multiple Choice

Which of the following is true regarding cortisol?

Cortisol is a neurotransmitter involved in the transmission of nerve impulses.

Cortisol is primarily responsible for the regulation of blood calcium levels.

Cortisol is secreted by the pituitary gland and controls the sleep-wake cycle.

Cortisol is a hormone produced by the adrenal cortex that helps regulate metabolism and the immune response.

Verified step by step guidance

Identify the role of cortisol in the body. Cortisol is a steroid hormone produced by the adrenal cortex, part of the adrenal glands located on top of the kidneys.

Understand the primary functions of cortisol. It plays a crucial role in regulating metabolism, particularly in the metabolism of carbohydrates, proteins, and fats. It also helps in managing stress and modulating the immune response.

Differentiate cortisol from neurotransmitters. Neurotransmitters are chemical messengers that transmit signals across synapses in the nervous system, whereas cortisol is a hormone that circulates in the bloodstream to exert its effects on various tissues.

Clarify the source of cortisol production. Unlike the options suggesting the pituitary gland, cortisol is produced by the adrenal cortex, not the pituitary gland. The pituitary gland does release ACTH (adrenocorticotropic hormone) which stimulates cortisol production.

Recognize the incorrect statements. Cortisol is not involved in the regulation of blood calcium levels (a role primarily of parathyroid hormone and calcitonin) nor is it directly involved in controlling the sleep-wake cycle (a role more associated with melatonin).
