Question: What cell type is found in adrenal medulla?...

What cell type is found in adrenal medulla?

Explanation

Solution

Adrenal glands, sometimes called suprarenal glands, are tiny triangular-shaped glands that sit on top of both kidneys. Hormones produced by the adrenal glands assist to control your metabolism, immunological system, blood pressure, stress response, and other vital processes. The cortex and the medulla are the two sections of the adrenal gland, and each is responsible for generating distinct hormones.

Complete answer:
The adrenal medulla is found in the middle of an adrenal gland, inside the adrenal cortex. The chromaffin cell is the most numerous cell found in the adrenal medulla.
The term comes from a long-known occurrence in which the adrenal gland takes on a brownish colour when fixed in a solution containing chromium salts due to the oxidation of catecholamines to melanin.
Chromaffin cells are also referred to as pheochromocytes.
Chromaffin cells have a columnar form and are basophilic in nature. They feature a granular cytoplasm due to hormone-containing granules, which may be observed at greater magnification under a microscope. They're grouped together, generally surrounding the medullary veins.
The granules in the cytoplasm of chromaffin cells contain stress hormones and the emergency hormones epinephrine, noradrenaline etc.

Note:
The inner portion of an adrenal gland, the adrenal medulla, regulates hormones that trigger the flight or fight response. The adrenal medulla secretes two hormones: epinephrine (adrenaline) and norepinephrine (noradrenaline), both of which have comparable roles. These hormones can increase the heart rate, increase blood flow to the muscles and brain, relax airway smooth muscles, and help with glucose (sugar) metabolism, among other things. They also regulate vasoconstriction.
