Endocrinology: Systems Physiology II

This lecture covers the general structure of the endocrine system, including the anatomy and histology of the hypothalamus, pituitary, thyroid, and adrenal glands. It explores the production of hormones such as T3, T4, aldosterone, glucocorticoids, and adrenaline, as well as the regulatory axes involved. The lecture delves into the intricate mechanisms of hormone production, the effects of thyroid hormones on metabolism, the role of aldosterone in the renin-angiotensin-aldosterone system, and the physiological effects of cortisol and adrenaline. It also discusses the control levels of the hypothalamo-hypophyseal-thyroid and hypothalamo-spinal cord-adrenal axes, emphasizing the importance of feedback mechanisms and the integration of neural and hormonal regulation.
