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.
