Question | Answer |
---|---|
Hormones | chemical messengers of the body; made primarily from proteins and steroids |
Pituitary gland | a small gland situated beneath the hypothalamus in the brain; two lobes (anterior & posterior); master gland |
Anterior pituitary | produces growth hormone, thyroid stimulating hormone, adrenocorticotropic hormone, prolactin, follicle-stimulating hormone, lutenizing hormone |
Growth hormone (GH) | controls the growth of bone and soft tissue |
Thyroid stimulating hormone (TSH) | stimulates thyroid to produce hormones for regulation of metabolism |
Adrenocorticotropic hormone (ACTH) | stimulates growth and development of adrenal cortex; stimulates adrenal cortex to produce steroid hormones |
Prolactin (PRL) | stimulates production of milk in the mammary glands;promotes breast development during pregnancy |
Follicle-stimulating hormone (FSH) | stimulates development of the follicle (structure in the ovaries that produce eggs); stimulates production of sperm |
Luteinizing hormone (LH) | acts with FSH to develop follicle in female; promotes ovulation; stimulates secretion of testosterone in male |
Posterior pituitary | produces antidiuretic hormone and oxytocin |
Antidiuretic hormone (ADH) | increases water reabsorption in kidneys to decrease urine formation; also called vasopressin |
Oxytocin | stimulates contraction of uterus in childbirth and milk letdown from mammary glands |
Thyroid gland | bowtie shaped gland in neck just below larynx; produces thyoxine, calcitonin |
Thyoxine | increases metabolic rate & regulates rate of growth |
Calcitonin | lowers blood calcium by inhibiting release of calcium from bone tissue |
Parathyroid glands | 4-5 tiny glands embedded in the posterior side of the thyroid gland |
Parathyroid hormone | promotes calcium mobilization from bone tissue and calcium absorption from intestines |
Pancreas | long gland inferior to the stomach contains alpha, beta, & delta islets of Langerhans (produce hormones) |
Insulin | produced by pancreas beta cells; lowers blood sugar levels by stimulating glucose uptake by cells |
Glucagon | produced by pancreas alpha cells; increases blood sugar levels |
Adrenal glands | Pyramid shaped glands located above the kidneys, divided into cortex & medulla |
Adrenal cortex | produces cortisol, aldosterone, and sex hormones |
Cortisol | released in response to stress; increases blood sugar levels, fatty acid immobilization |
Aldosterone | helps regulate blood pressure by promoting sodium uptake & potassium secretion by the kidneys |
Sex hormones | regulate sexual development and sex drive (supplement hormones produced by the gonads) |
Gonads | glands that produce sex cells and sex hormones |
Testosterone | regulates production of sperm cells & development of penis & secondary glands; causes development of secondary male sexual characteristics |
Estrogen | regulates menstrual changes and sex drive;development of secondary sex organs and secondary sexual characteristics |
Progesterone | prepares uterus for implantation of a fertilized egg; prevents spontaneous abortion by preserving uterine lining |
Thymus | Organ in the mediastinum above the heart, produces t-cells |
Thymosin | stimulates t-cells previously produced |
Pineal gland | small gland found in the midbrain of the brainstem |
Melatonin | regulates sleep-wake cycles of the body. |
Renin | produced by kidneys; stimulates water retention increasing blood pressure |
Erythropoieten | produced by kidneys; stimulates production of red blood cells |
Human chorionic gonadotropin (hCG) | produced by embryo in early pregnancy to stimulate progesterone production, which enriches the uterus with a thick lining of blood vessels and capillaries so that it can sustain the growing fetus. |
