The Endocrine System
| Term | Definition |
|---|---|
| What hormones / glands are in the anterior pituitary? | Growth hormone (GH), Thyroid-stimulating hormone (TSH), Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), Prolactin gland (PRL), Adrenocorticotropic hormone (ACTH), Melanocyte-stimulating hormone (MSH). |
| Growth hormone (GH) locations and function. | Cartilage, bone, skeletal muscles, liver, tissue. Stimulates secretion of hormones for body growth and metabolism. |
| Thyroid-stimulating hormones (TSH) locations and function. | Thyroid gland. Stimulates growth of thyroid gland and secretions of its hormones. |
| Follicle-stimulating hormones (FSH) locations and function. | Testes and ovaries. Stimulates sperm production for men. Stimulates oocyte production and estrogen secretion for women. |
| Luteinizing hormones (LH) locations and function. | `Testes and ovaries. Stimulates secretion of testosterone for men. Triggers ovulation, stimulates secretion of estrogen and progesterone for women. |
| Prolactin gland (PRL) locations and function. | Mammary glands. Stimulates production and secretion of milk. |
| Adrenocorticotropic hormone (ACTH) locations and function. | Adrenal cortex. Stimulates secretion and hormones by adrenal cortex. |
| Melanocyte-stimulating hormone (MSH) locations and function. | Skin. Darkens skin pigmentation. |
| What hormones / glands are in the posterior pituitary? | Antidiuretic hormone (ADH) and Oxytocin gland (OT). |
| Antidiuretic hormone (ADH) locations and function. | Kidneys. Decrease water loss, decrease urine production from kidneys, increase reabsorption of water into blood. |
| Oxytocin gland (OT) locations and function. | Uterus and mammary glands. Stimulates uterine contractions and milk ejection during suckling. |
| What hormones / glands are in the thyroid? | T3 , T4, and calcitonin. |
| T3 and T4 locations and function. | Most body cells. Increase metabolism and BMR. |
| Calcitonin locations and function. | Osteoclast cells in bones. Decrease blood calcium levels. |
| What hormones / glands are in the parathyroid? | Parathyroid hormones (PTH). |
| Parathyroid hormones (PTH) locations and function. | Osteoclast cells in bones. Increases blood calcium levels, break down bone matrix. |
| What hormones / glands are in the adrenal cortex? | Zona glomerulus, Zona fasciculata, Zona reticularis., Aldosterone, Androgens (DHEA) |
| Zona glomerulus locations and function. | Kidneys. Increase reabsorption of sodium and water into blood. |
| Zona fasciculata locations and function. | Liver, muscle, defense cells. Increase resistance to stress and blood glucose levels, decrease inflammation. |
| Zona reticularis locations and function. | Uterus, mammary glands, sex cells. Insignificant in males; increase sex drive in women. |
| What hormones / glands are in adrenal medulla? | Epinephrine (NE) and Norepinephrine (NE). |
| Epinephrine and Norepinephrine (NE) locations and function. | Fight-or-flight |
| What hormones / glands are in the pancreas? | Insulin and Glucagon. |
| Insulin locations and function. | Most body cells. Decreases blood glucose levels by transporting into body cells. |
| Glucagon locations and function. | Liver. Increase blood glucose levels by having liver break down glycogen into glucose. |
| What hormones / glands are in the ovaries? | Estrogen and Progesterone. |
| Estrogen and progesterone locations and function. | Uterus, mammary glands, female sex cells. Stimulates development, helps regulate menstrual cycles. |
| What hormones / glands are in the testes? | Testosterone. |
| Testosterone locations and function. | Testes, muscle, male sex cells. Stimulates development, male sex drive, regulates sperm. |
| What hormones / glands are in the Pineal? | Melatonin. |
| Melatonin locations and function. | Brain. Helps set biological clock. |
| What hormones / glands are in the thymus? | Thymosin. |
| Thymosin locations and function. | T cells, white blood cells used in immune response. Promotes the maturation of T cells for the immune response. |
| What is NOT hormonous? | Exocrine glands. |
| Endocrine glands | Short bursts, maintain homeostasis, prevent over or under production. |
| Thyroid glands | Increase BMR, maintain body temp, protein synthesis, increase glucose and fat for ATP production. |
| Anterior Pituitary glands | Secretion of hormones. |
| Posterior pituitary glands | Do NOT synthesis hormones |
| Hypothalumus | Major link between nervous and endocrine system. Secretes releasing and inhibiting hormones that influence the pituitary glands. |
| Pancreatic islets | Arranged in clusters called acini. |
| Acini | Produce digestive enzymes that deliver to the gastrointestinal tract. |
| 4 types of pancreatic islet cells | Alpha, Beta, Delta, F. |
| Alpha cells | Glucagon, increases blood glucose consentration. |
| Beta cells | Insulin, decreases blood glucose concentraion. |
| Delta cells | Somatostatin, secretion of glucose and insulin. |
| F cells | pancreatic polypeptide, secretion of somatostatin, pancreatic digestive enzymes, and gallbladder contraction. |
| NOT a part of endocrine but produce hormones | Skin, GI tract, Placenta, Kidneys, Heart, Adipose tissue. |
| Pituitary gland location | Hanging off the brain, attached to the infundibulum, which is attached to the hypothalamus. |
| Thyroid gland location | Butterfly-shaped, and behind trachea in throat. Right and left lobe connected together by isthmus. |
| Parathyroid gland location | On the back of the thyroid gland, one is towards top, another is towards bottom. |
| Adrenal gland location | On top of kidneys. |
| Pancreatic islets | Both endocrine and exocrine. |
| Pineal gland location | Towards the back of the brain, near branch. |
| Thymus gland location | Behind sternum, in between lungs. |
