Students Will Review:
This chapter helps students review the concepts in a human endocrine system study guide unit of a standard human biology study guide course. Topics covered include:
- Definition and function of hormones of the human endocrine system
- Functions and hormones of the hypothalamus and pituitary and thyroid glands
- Cells and hormones of the parathyroid gland
- Hormones, function and anatomy of the pancreas
- Symptoms and treatment of pituitary, thyroid and pancreas disorders
- Hormones of the adrenal glands and their role in the stress response, sex and fluid balance
- The pineal gland and its relationship to the sleep-wake cycle
- Hormones involved in reproduction and gestation
1. Hormones: Definition, Function & Intro to the Endocrine System
This lesson introduces the endocrine system and provides a brief overview of each endocrine gland. It also provides the definition of hormones and describes their general function inside the body.
2. What Is the Pituitary Gland? - Functions, Hormones & Hypothalamus
In this lesson, we'll discuss the functions of the anterior and posterior portions of the pituitary gland, the hormones they release and the relationship with the hypothalamus.
3. Pituitary Dysfunction: Disorders and Symptoms
The pituitary gland secretes hormones that affect growth, reproductive ability, and water retention. If there is a hypo- or hyper-secretion of these hormones, the result can be a number of conditions, including pituitary dwarfism, gigantism, acromegaly, sterility, or diabetes insipidus.
4. The Thyroid Gland: Functions, Calcitonin & TSH
Your thyroid gland produces the hormones T3 and thyroxine (T4), which play a role in metabolism. Your thyroid also produces calcitonin, which helps regulate blood calcium levels. In this lesson, you will learn about the thyroid gland and its hormones, including how they are regulated by TSH.
5. Thyroid Disorders: Hyperthyroidism, Hypothyroidism & Thyroidectomy
The thyroid gland produces hormones that help set your metabolic rate. This lesson will discuss conditions of the thyroid gland, including hyperthyroidism and hypothyroidism, and their related symptoms.
6. Parathyroid Gland: Calcium Metabolism, Osteoclasts & PTH
The parathyroid glands are tiny endocrine glands found on the posterior surface of the thyroid gland. In this lesson,, you will learn about the parathyroid glands, and the role parathyroid hormone plays in maintaining normal blood calcium levels.
7. Pancreas: Functions, Anatomy & Insulin Production
The islets of Langerhans within your pancreas produce the hormones insulin and glucagon. In this lesson, you will learn how these hormones regulate your blood sugar level in opposite ways.
8. Disorders of the Pancreas: Types, Symptoms & Treatments
The pancreas produces insulin. If the pancreas is incapable of producing insulin or cells do not respond to this hormone, then a person can develop diabetes mellitus. In this lesson, you will learn about diabetes and how it relates to the pancreas.
9. Adrenal Glands: Epinephrine, Norepinephrine & Stress Adaptation
The adrenal medulla is the central portion of the adrenal gland. In this lesson, you will learn about the two hormones secreted by the adrenal medulla - epinephrine and norepinephrine - and how they help you deal with short-term stressors.
10. Adrenal Cortex: Glucocorticoids and Androgens
The adrenal cortex secretes steroid hormones. In this lesson, you will learn about two of these steroid hormones: glucocorticoids, which help you deal with long-term stress, and androgens, which influence male sexual characteristics.
11. Adrenal Cortex: Aldosterone and Body Fluid Balance
Mineralocorticoids are a type of steroid hormone secreted by the adrenal cortex. In this lesson, you will learn about the main mineralocorticoid, aldosterone, and how it regulates your body's salt and water balance.
12. Adrenal Gland Disorders & Treatments: Addison's Disease and Prednisone
The adrenal glands secrete hormones that help maintain balance in your body. But, if these hormones are over- or under-secreted, disease can develop. In this lesson, you will learn about disorders of the adrenal glands, including Addison's disease and Cushing's syndrome, as well as their treatments.
13. Pineal Gland, Functions, Melatonin & Circadian Rhythm
Deep inside your brain sits a very small endocrine gland called the pineal gland. This tiny gland secretes the hormone melatonin, and in this lesson, you will learn about the role melatonin plays in regulating sleep and wake cycles.
14. Hormones of the Testes and Ovaries: Functions & Anatomical Features
The testes and the ovaries secrete steroid hormones that help you grow and develop. In this lesson, we will learn about the female hormones, estrogen and progesterone, and the male hormone, testosterone, and how these hormones influence the development of secondary sex characteristics.
15. Hormones of the Placenta: Estrogen, Progesterone & hCG
The placenta is an endocrine gland that is only present during pregnancy. In this lesson, you will learn about the hormones it produces, including human chorionic gonadotropin (hCG), progesterone, estrogen, and human placental lactogen (hPL).
16. Hormones of the Anterior Pituitary Gland: Names & Functions
The anterior pituitary gland secretes six hormones. In this lesson, you will learn the functions of the hormones: growth hormone (GH), prolactin (PRL), follicle-stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), and thyroid-stimulating hormone (TSH).
