Study Notes
Hormones and Their Functions
- Oxytocin is produced in the hypothalamus and released by the posterior pituitary, playing important roles in childbirth and lactation.
- Antidiuretic hormone (ADH) affects the nephrons of the kidney.
- Adrenocorticotropic hormone (ACTH) stimulates the adrenal cortex to produce glucocorticoids and mineralocorticoids.
- Gonadotropins stimulate the growth and functioning of the ovaries and testes.
Thyroid Hormones
- Thyroid-stimulating hormone (TSH) activates the thyroid to produce T3 and T4, involved in maintaining the basal metabolic rate.
Milk Production
- Prolactin stimulates milk production in females.
Growth and Development
- Growth hormone stimulates the growth of muscle, cartilage, and bone, and causes many cells to speed up protein synthesis and cell division.
Endocrine Glands
- The pituitary gland is composed of glandular tissue and produces hormones that stimulate growth, metabolic rate, milk production, and glucocorticoid production.
- The adrenal gland is located 'on top' of the kidneys and secretes glucocorticoids, mineralocorticoids, and small amounts of estrogen and testosterone.
Hormone Groups
- Glucocorticoids are involved in glucose metabolism and ion balance.
- Sex hormones help maintain secondary male and female sex characteristics.
- Catecholamines are non-steroid and involved in the 'fight or flight' response.
Other Hormones
- The parathyroid gland is responsible for secreting parathyroid hormone (PTH).
- Glucagon stimulates liver and muscle cells to break down glycogen into glucose, thus increasing blood glucose levels.
- The thymus gland is located in the mediastinum.
- The pineal gland secretes melatonin.
- Parathyroid hormone (PTH) is involved in calcium ion homeostasis by stimulating the absorption of calcium and phosphate along the digestive tract.
- Somatostatin inhibits the production of growth hormone and other hormones.
- Aldosterone decreases blood volume by causing water loss to the urine and suppression of thirst.
- Cholecystokinin (CCK) stimulates the release of bile.
- Gastrin stimulates stomach secretions.
- Aldosterone is involved in blood pressure and blood volume regulation.
- Erythropoietin (EPO) stimulates the production of red blood cells, thereby increasing blood volume and pressure.
- The thymus gland secretes hormones for lymphatic cell maturation, including thymosin and thymopoietin.
