Endocrine System
Question | Answer |
---|---|
estrogen | help develop secondary characteristics in females |
hemostasis | the stopping of a flow of blood |
ductless | transport hormones in the blood |
endocrine system | collection of glands of an organism that secrete hormones directly into the circulatory system to be carried towards distant target organs |
vas deferens | carries semen |
parathormone | controls the metabolism of calcium |
glucagon | from Alpha cells increase blood sugar |
LH | a hormone secreted by the anterior lobe of the pituitary gland that in the female stimulates ovulation and the development of corpora lutea and in the male the development of interstitial tissue in the testis |
adrenaline | raises blood sugar level and increases heart beat and breathing rates |
negative feedback | when a high level of a particular hormone in the blood may inhibit further secretion of that hormone, or where the result of a certain action may inhibit further performance of that action |
gigantism | oversecreation of growth hormone, occurs during childhood |
hypothalamus | controls pituitary gland, receives info from nervous system |
testosterone | an androgen that affects the secondary characteristics in men |
diabetes | underseretion of insulin, high blood sugar |
prolactin | hormone released from the anterior pituitary gland that stimulates milk production after childbirth |
dwarfism | under secretion of growth hormone |
acromegaly | occurs in adults, bones of hands, face and feet are enlarged, release of growth hormone |
goiter | not enough iodine in diet, causes swelling of thyroid gland |
thymus | helps develop the immune system |
thyroxine | hormone produced by the thyroid gland, acting to increase metabolic rate and so regulating growth and development |
epididymis | a highly convoluted duct behind the testis, along which sperm passes to the vas deferens |
testes | secrete male sex hormones called androgens |
FSH | hormone produced by the anterior lobe of the pituitary gland that stimulates the growth of the ovum-containing follicles in the ovary and activates sperm-forming cells |
oxytocin | hormone released by the pituitary gland that causes increased contraction of the uterus during labor and stimulates the ejection of milk into the ducts of the breasts |
ovulation | discharge ova or ovules from the ovary |
pituitary gland | serve to link the nervous system to other glands and metabolic functions |
corpus luteum | hormone-secreting structure that develops in an ovary after an ovum has been discharged but degenerates after a few days unless pregnancy has begun |
cowpers | two small glands lying on either side of the male urethra below the prostate gland and discharging a secretion into the semen |
hypothalamus | links nervous system to other glands and metabolic functions, contains pituitary glands |
blood sugar | the concentration of glucose in the blood |
uterus | the organ in the lower body of a woman or female mammal where offspring are conceived and in which they gestate before birth; the womb |
hormones | a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action |
cervix | the narrow necklike passage forming the lower end of the uterus |
neurotransmitter | a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure |
fallopian tubes | either of a pair of tubes along which eggs travel from the ovaries to the uterus |
vagina | the muscular tube leading from the external genitals to the cervix of the uterus in women and most female mammals |
progesterone | a steroid hormone released by the corpus luteum that stimulates the uterus to prepare for pregnancy |
