Endocrinology | Thyroid Overview

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this endocrine physiology lecture, Professor Zach Murphy provides an essential overview of the thyroid gland, highlighting its structure, function, and role in maintaining metabolic homeostasis. This foundational session sets the stage for deeper dives into thyroid hormone synthesis, regulation, and systemic effects. We begin by reviewing the anatomy of the thyroid gland, including its lobular structure, follicular cells, and colloid. The lecture then transitions into a simplified outline of thyroid hormone production (T3 and T4) and how it is controlled by the hypothalamic-pituitary-thyroid axis through TRH and TSH. Key physiologic principles such as negative feedback regulation are explained, with clinical relevance tied into how disruptions in this axis can lead to thyroid dysfunction. Minor correction 2:43 — Low T3 and T4 levels lead to a positive feedback signal to the paraventricular nucleus (PVN), resulting in increased TRH, increased TSH, and ultimately restoration of T3 and T4 levels.
