In this lesson you will learn about the anatomy and physiology of the thyroid gland, the parathyroid glands and the adrenal glands and their roles.
By the end of this lesson, students should be able to:
- explain how the thyroid regulates metabolisms
- differentiate between T3 and T4 hormones and their binding to cell receptors.
- explain how the T3, T4 and TSH levels regulate a hormonal cascade via feedback mechanism.
- describe thyroid-related disorders such as hypothyroidism, hyperthyroidism, Graves disease and goiter.
- describe the anatomy and physiology of the parathyroid gland.
- explain the roles of Calcitonin and Parathyroid hormone (PTH) on blood calcium homeostasis.
- describe the anatomy and physiology of the adrenal glands
- explain the roles of hormones secreted by the adrenal cortex (epinephrine and norepinephrine) and adrenal medulla (mineralocorticoids and glucocorticoids) on short-term and long-term responses to stress.
Let’s examine the anatomy and physiology of the thyroid and parathyroid glands and blood calcium homeostasis in the video lesson below. Once again take detailed notes as you watch this lesson.
The second video lesson introduces the anatomy and physiology of the adrenal glands. Please watch it carefully and take detailed notes.
