About this document
Adrenal Medulla: Hormones and Functions by nurahasmirul is a document available to read on EtoBox.
The adrenal medulla, composed of chromaffin cells, secretes catecholamines such as adrenaline and noradrenaline, which are released in response to acetylcholine from preganglionic neurons. These hormones have various physiological actions including increasing heart rate, blood pressure, and metabolic activity. Pheochromocytoma, a benign tumor of the adrenal medulla, causes excessive catecholamine secretion leading to symptoms like palpitations, headaches, and hypertension.
