Insulin is the primary hormone involved in glucose homeostasis, promoting the uptake and utilization of glucose by cells, thereby lowering blood glucose levels.

Glucagon counteracts the effects of insulin, elevating blood glucose levels by stimulating the breakdown of glycogen (glycogenolysis) and the production of glucose from non-carbohydrate sources (gluconeogenesis).

Thyroxine, also known as T4, is the primary hormone produced by the thyroid gland. It plays a crucial role in regulating basal metabolic rate, influencing the rate at which the body burns calories and produces energy.

Cortisol is a stress hormone that helps the body respond to various stressors. It mobilizes energy stores by stimulating the breakdown of proteins and fats, providing the body with readily available energy during stressful situations.

Growth hormone, also known as somatotropin, is primarily responsible for regulating growth and development in children and adolescents. It stimulates the production of insulin-like growth factor-1 (IGF-1), which promotes cell growth and differentiation.

Epinephrine, also known as adrenaline, is a hormone produced by the adrenal glands. It plays a crucial role in preparing the body for the 'fight or flight' response by increasing heart rate, blood pressure, and blood glucose levels.

Parathyroid hormone is produced by the parathyroid glands and plays a key role in regulating calcium and phosphate metabolism. It increases blood calcium levels by stimulating the release of calcium from bones and promoting calcium absorption from the intestines.

Calcitonin is a hormone produced by the thyroid gland. It helps to lower blood calcium levels by inhibiting the release of calcium from bones and promoting calcium excretion by the kidneys.

Estrogen is a female sex hormone primarily produced by the ovaries. It plays a crucial role in regulating reproductive functions, including the menstrual cycle and pregnancy. Additionally, estrogen influences secondary sexual characteristics, such as breast development and body fat distribution.

Progesterone is a female sex hormone primarily produced by the ovaries. Its main function is to prepare the uterus for pregnancy by thickening the uterine lining and promoting the development of blood vessels to support the growth of a fertilized egg.

Testosterone is a male sex hormone primarily produced by the testes. It plays a crucial role in regulating male reproductive functions, including sperm production and sexual drive. Additionally, testosterone influences secondary sexual characteristics, such as muscle mass, facial hair growth, and voice deepening.

Growth hormone is a hormone produced by the pituitary gland. It plays a crucial role in stimulating growth and development in children and adolescents. Growth hormone promotes the production of insulin-like growth factor-1 (IGF-1), which directly influences cell growth and differentiation.

Antidiuretic hormone (ADH), also known as vasopressin, is produced by the hypothalamus and stored in the pituitary gland. It plays a crucial role in regulating water and electrolyte balance by promoting water reabsorption in the kidneys, thus reducing urine output and maintaining blood osmolality.

Aldosterone is a hormone produced by the adrenal glands. It plays a crucial role in regulating sodium and potassium balance in the body. Aldosterone promotes sodium reabsorption and potassium excretion by the kidneys, helping to maintain blood pressure and fluid volume.

Melatonin is a hormone produced by the pineal gland. It plays a crucial role in regulating sleep-wake cycles by promoting drowsiness and preparing the body for sleep. Melatonin levels rise in the evening and decrease in the morning, helping to establish the body's natural circadian rhythm.
