What is the master gland of the endocrine system?

The pituitary gland is a small but crucial part of the endocrine system, often called the "master gland" because it controls the activity of other endocrine glands. It releases hormones that regulate a wide range of bodily functions, including growth, metabolism, and reproduction.

What does growth hormone do in children?

Growth hormone (GH) is a powerful hormone produced by the pituitary gland that plays a vital role in childhood growth and development. It helps stimulate the growth of bones, muscles, and other tissues.

What happens when the body produces too much growth hormone in adults?

Acromegaly is a disorder caused by excessive production of growth hormone in adults. It leads to abnormal growth of hands, feet, and face, often resulting in a disproportionate appearance.

What are endocrine glands?

Endocrine glands are a special type of gland that release their secretions directly into the bloodstream. These secretions, called hormones, travel throughout the body to target specific organs or tissues.

How do insulin and glucagon work?

Insulin and glucagon are two key hormones produced by the pancreas that work together to regulate blood glucose levels. Insulin helps lower blood sugar by promoting glucose uptake into cells, while glucagon raises blood sugar by stimulating the release of glucose from storage.

Study Notes

Endocrine System

The pituitary gland is known as the master gland of the endocrine system.

Growth Hormone (GH)

The primary function of GH in children is to promote growth and development.

Growth Hormone Disorder

Excessive secretion of GH in adults results in a disorder called acromegaly.

Types of Glands

Endocrine glands are a type of gland that release their secretions directly into the bloodstream.

Insulin and Glucagon

The main function of insulin and glucagon is to regulate blood sugar levels:
- Insulin lowers blood sugar levels by facilitating glucose uptake in cells.
- Glucagon raises blood sugar levels by stimulating glucose release from storage sites.
