🗑
simple goiter   Enlargement of thyroid  
🗑
PTH   Increases blood calcium  
🗑
Mineralocorticoids   Increases blood sodium and decreases body potassium  
🗑
Luteinizing hormone   Ovulating hormone  
🗑
Testerone   Masculinizing hormone  
🗑
Thymosin (Thymus)   Development and function of immune system  
🗑
Melatonin (Pineal)   Regulates the body's internal clock  
🗑
Hyper-secretion   Oversecretion of hormones  
🗑
GH (Anterior Pituitary)   Growth hormone  
🗑
Hormones   chemical mechanism used in endocrine system  
🗑
Endocrinology   study of endocrine system  
🗑
Diabetes mellitus   insulin hypersecretion  
🗑
Prostaglandins   tissue hormone  
🗑
negative feedback   mechanism that reverses direction of change  
🗑
Nonsteroid hormones   hormone synthesized primarily from amino acids  
🗑
Tropic hormones   Tropic hormones: hormones that target other endocrine glands and stimulate their growth and secretion.  
🗑
Sex hormones   hormones that target reproductive tissues.  
🗑
Anabolic hormones   hormones that stimulate anabolism in target cells.  
🗑
Nonsteroid hormones A   which must have cellular receptor proteins at the surface of the plasma membrane.  
🗑
Nonsteroid hormones B   The interaction between nonsteroid hormones and receptor proteins activates a cascade of chemical reactions resulting in the target cell's response to the hormone.  
🗑
Nonsteroid hormones C   Nonsteroid hormones have a quick response  
🗑
Steroid hormones   lipid soluble and can pass directly through the cell membrane of the target cell to react with the receptors inside the cell.  
🗑
Synergism:   this phenomenon occurs when combinations of hormones acting together have a greater effect on a target cell than the sum of the effects that each would have if acting alone.  
🗑
Permissiveness:   this occurs when a small amount of one hormone allows a second one to have its full effects on a target cell.  
🗑
Antagonism:   occurs when a small amount of one hormone produces the opposite effects of another hormone; used to "fine tune" the activity of target cells with great accuracy.  
🗑
Steroid hormones B   are manufactured by endocrine cells from cholesterol.  
🗑
Anabolic steroid   hormones are synthetic substances that are related to the male sex hormones  
🗑
Anabolic steroid B   promote the release of the growth hormone, which stimulates growth, especially skeletal growth.  
🗑
Adrenal Medulla   inner portion of AG secretes epinephrine and noepinephrine  
🗑
Hypothalamus   secretes releasing hormones ADH and Oxytocin  
🗑
Pineal Gland   secretes Melatonin  
🗑
Tropic hormone   stimulates another endocrine gland to grow and secrete hormones  
🗑
Oxytocin   stimulates contraction of uterine muscle  
🗑
sella turcica   small depression of the sphenoid bone shaped like a saddle  
🗑
Antidiuretic hormone (ADH):   prevents the formation of a large volume of urine, thereby helping the body to conserve water  
🗑
Parathyroid hormone (PTH)   acts on bone and the kidneys  
🗑
Pancreatic Islets Alpha cells   secrete the hormone glucagon, which raises the blood glucose levels.  
🗑
Pancreatic Islets Beta cells   secrete the hormone insulin, which serves an antagonistic function to glucagon by lowering blood glucose levels.  
🗑
ovaries secrete   ovaries secrete estrogen, the "feminizing hormone,"  
🗑
corpus luteum secretes   progesterone, which assists with the preparation of the uterus for pregnancy.  
🗑
testes produce   the male sex hormone testosterone  
🗑
Thymosin   is a group of hormones produced by the thymus that play a significant role of the body's immune system  
🗑
Melatonin   hormones that the pineal gland, is thought to be related to the body's internal clock and sleep cycle.  
🗑
chorionic gonadotropins   are excreted in the urine. This tropic hormone is secreted by cells of the placenta, and its presence is detected by most pregnancy tests marketed today.  
🗑
