Study Notes

Functions of Endocrine Hormones

Endocrine glands produce hormones, chemical messengers that play crucial roles in regulating various physiological processes within the body. These hormones function by interacting with specific target cells to initiate responses and maintain homeostasis. Some essential functions of endocrine hormones include growth promotion, tissue repair, stress response, metabolic regulation, sexual development, immune system modulation, and muscle growth. Each hormone serves its unique role to ensure optimal body functioning. Below are some examples of the functions of specific endocrine hormones and their associated glands.

Insulin (Pancreatic Islets)

Insulin is primarily produced by beta cells of the pancreatic islets and plays an essential role in glucose regulation. It promotes the absorption of glucose into skeletal muscles, fatty tissue, liver, and other cells throughout the body. This helps maintain blood sugar levels within a healthy range, preventing hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar).

Growth Hormone (Anterior Pituitary)

Growth hormone, secreted by the anterior pituitary gland, stimulates the growth of cartilage and bone in children, resulting in linear growth. It also contributes to metabolism regulation, stimulating the breakdown of lipids and proteins for energy production. Additionally, it promotes cell division and tissue repair in adults, supporting overall wellbeing.

Thyroid Hormones (Thyroid Gland)

Thyroid hormones, triiodothyronine (T3) and thyroxine (T4), are released from the thyroid gland and play crucial roles in regulating metabolism, heart rate, and brain development. They promote oxidative reactions that generate heat, enhance protein synthesis, and contribute to efficient use of energy within the body.

Adrenocortical Steroids (Adrenal Cortex)

The outer layer of the adrenal gland produces steroid hormones called corticosteroids, which include mineralocorticoids, glucocorticoids, and sex hormone precursors. These hormones manage electrolyte balance, stress response, inflammation reduction, and immune system activation.

Gonadal Steroids (Testes, Ovaries)

In males, testosterone is produced by Leydig cells in the testes and supports libido, aggression, and secondary sexual characteristics. Testosterone also stimulates the conversion of cholesterol into more potent hormones such as estrogen in both men and women. In females, the ovaries produce estradiol, estriol, and progesterone, which regulate menstrual cycles, pregnancy, and ovulation.

These examples illustrate how various endocrine hormones work together to maintain homeostasis and support diverse physiological processes within the body.
