About This Chapter
Function & Parts of the Endocrine System - Chapter Summary
In this chapter on the function and parts of the endocrine system, brief lessons cover topics such as the adrenal cortex and adrenal glands. Additionally, you will learn about the important functions of hormones. After completing the chapter, you should be able to do the following:
- List functions regulated by hormones
- Discuss anatomic features of the hypothalamus
- Explain how parathyroid hormones help to maintain normal blood calcium levels
- Recall the functions of six hormones secreted by the anterior pituitary gland
- Detail functions and side effects of human growth hormones
- Discuss factors that alter the function of ADH in the body
- Explain the meaning of negative feedback in biology
- Describe how diabetes relates to the pancreas
Our instructors present these lessons in a manner that ensures the material is easy to understand. If you find yourself struggling with a specific topic, you can use the Help feature to submit questions to instructors. A brief quiz is available for each lesson, which is a great way to test your knowledge of what you have reviewed.
1. Endocrine System Function & Hormone Regulation
Our hormones play a big part in how we feel and behave throughout the day. Hormones also affect important bodily functions. What other functions do our hormones regulate? Find out in this lesson on the endocrine system!
2. Hypothalamus: Function, Role & Definition
This lesson describes the hypothalamus as it relates to the endocrine system. It will examine the anatomic features of the hypothalamus and how it uses the pituitary gland to communicate with the rest of the body. A short quiz will follow.
3. 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.
4. 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.
5. The Functions of Important Hormones
This lesson presents the function of each of the major hormones in the body and identifies the gland that secretes it. Take the short self-assessment quiz when you are through.
6. 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).
7. Human Growth Hormones: Uses & Side Effects
This lesson is about human growth hormone, or HGH. We will discuss what HGH is, its normal function in humans, conditions for which it is prescribed, its side effects, and ways it has been abused for unintended use.
8. What is ADH? - Definition & Function
Learn what ADH stands for and what it means. We will take a look into the function of ADH in the body as well as factors that can alter its function in the body. There is a short quiz to follow.
9. 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.
10. 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.
11. What is Negative Feedback in Biology? - Definition & Examples
Negative feedback is a key regulatory mechanism for physiological function in living things. Learn the definition, explore some examples and find out how this process happens in your body. Test your new knowledge at the end with a quiz.
12. 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.
