Endocrine System Overview

Study Notes

The endocrine system is a network of glands that produce and regulate hormones in the body.
Hormones are chemical messengers that help control various bodily functions, such as growth and development, metabolism, and reproductive processes.

Pituitary Gland: often referred to as the "master gland" because it regulates the function of other endocrine glands.
- Produces hormones that stimulate or inhibit the production of hormones in other glands.
Thyroid Gland: produces thyroid hormones that regulate metabolism, growth, and development.
Adrenal Glands: produce hormones that regulate stress response, blood pressure, and electrolyte balance.
Pancreas: produces hormones that regulate blood sugar levels, such as insulin and glucagon.
Ovaries (in females) and Testes (in males): produce sex hormones that regulate reproductive processes.
Hypothalamus: produces hormones that regulate body temperature, hunger, and thirst.

Regulation of Growth and Development: hormones regulate growth and development during childhood and adolescence.
Metabolism: hormones regulate metabolic processes, such as energy production and storage.
Electrolyte and Water Balance: hormones regulate the balance of electrolytes and water in the body.
Reproductive Processes: hormones regulate reproductive processes, such as puberty, menstruation, and fertility.
Stress Response: hormones regulate the body's response to stress.

Negative Feedback Loop: a mechanism by which the endocrine system regulates hormone production, where the hormone produced by a gland feedbacks to the pituitary gland to regulate its production.
Positive Feedback Loop: a mechanism by which the endocrine system stimulates hormone production, where the hormone produced by a gland stimulates the pituitary gland to produce more hormone.

Hypothyroidism: a condition in which the thyroid gland does not produce enough thyroid hormones.
Hyperthyroidism: a condition in which the thyroid gland produces too much thyroid hormones.
Diabetes: a condition in which the pancreas does not produce enough insulin or the body is unable to use insulin effectively.
Growth Hormone Deficiency: a condition in which the pituitary gland does not produce enough growth hormone.

The adrenal glands produce hormones that regulate stress response, blood pressure, and electrolyte balance.
The pancreas produces hormones that regulate blood sugar levels, such as insulin and glucagon.

The endocrine system regulates the balance of electrolytes and water in the body.
The endocrine system regulates reproductive processes, such as puberty, menstruation, and fertility.
The endocrine system regulates the body's response to stress.

The endocrine system uses a negative feedback loop to regulate hormone production, where the hormone produced by a gland feedbacks to the pituitary gland to regulate its production.
The endocrine system uses a positive feedback loop to stimulate hormone production, where the hormone produced by a gland stimulates the pituitary gland to produce more hormone.

Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormones.
Hyperthyroidism is a condition in which the thyroid gland produces too much thyroid hormones.
Diabetes is a condition in which the pancreas does not produce enough insulin or the body is unable to use insulin effectively.
Growth hormone deficiency is a condition in which the pituitary gland does not produce enough growth hormone.
