thyr/o | thyroid gland (steroid) |
thyroid/o | thyroid gland (steroid) |
adrenal glands | located on the superior surface of each kidney; the outer adrenal cortex secretes steroid hormones, and the inner adrenal medulla secretes epinephrine and norepinephrine; also called suprarenal glands |
suprarenal glands | located on the superior surface of each kidney; the outer adrenal cortex secretes steroid hormones, and the inner adrenal medulla secretes epinephrine and norepinephrine; also called adrenal glands |
steroid hormones | hormones secreted by the adrenal cortex |
glucocorticoids | hormones that regulate carbohydrate metabolism and have anti inflammatory effects; cortisol is the most significant glucocorticoid |
mineralocorticoid | hormones that maintain salt and water balance |
androgens | hormones that influence development and maintenance of male sex characteristics (facial hair, deep voice) |
catecholamines | hormones secreted by the adrenal medulla that affect the sypathetic nervous system in stress response |
epinephrine | hormone that is secretes in response to fear or physical injury; also called adrenaline |
adrenaline | hormone that is secretes in response to fear or physical injury; also called epinephrine |
norepinephrine | hormone that is secreted in response to hypotension (low blood pressure) and physical stress |
ovaries | located on both sides of the uterus in the female pelvis; secretes estrogen and progesterone |
estrogen | hormone that is responsible for the development of female secondary sex characteristics |
progesterone | hormone that regulate uterine conditions during pregnancy |
islets of Langerhans of the pelvis | endocrine tissue within the pancreas (the organ located behind the stomach, in front of the 1st and 2nd lumbar vertebrae); secretes insulin and glucagon; also called pancreatic islets |
insuin | a hormone secreted by the beta cells of the islets of Langerhans that is responsible for regulating the metabolism of glucose (insulin=island) |
glucagon | a hormone secreted by the alpha cells of the islets of Langerhans that regulates carbohydrate metabolism by raising blood sugar |
parathyroid glands | 2 paired glands located on the posterior aspect of the thyroid gland in the neck; secrete parathyroid hormone (PTH) |
parathyroid hormone (PTH) | hormone that regulates calcium and phosphorus metabolism |
pineal gland | located in the center of the brain; secretes melatonin and serotonin |
melatonin | hormone that is involved with circadian rhythm (24 hour cycle); affects the onset of puberty |
serotonin | hormone that constricts blood vessels and acts as a neurotransmitter |
pituitary gland | |
hypophysis | pituitary gland |
anterior pituitary | anterior lobe of the pituitary gland; also called adenohypophysis |
adenohypophysis | anterior lobe of the pituitary gland; also called anterior pituitary |
thyroid stimulating hormone (TSH) | hormone that stimulates secretion from the thyroid gland |
adrenocorticotropic hormone (ACTH) | hormone that stimulates the secretion from adrenal cortex |
follicle stimulating hormone (FSH) | hormone that initializing the growth of ovarian follicle; stimulates the secretions of estrogen in females and the production of sperm in males |
