AP2 endocrine Adrenal Glands, Pineal glands and thymus, Exams of Nursing

The adrenal glands, pineal glands, and thymus, and the hormones they produce. It covers the functions of epinephrine, norepinephrine, dopamine, cortisol, and aldosterone, and where they are produced in the body. It also explains the role of chromaffin cells in mediating immediate responses to stressors. a brief overview of the endocrine system and its importance in maintaining homeostasis.
