A&P of Endocrine System Flashcards
It takes longer for a ________-releasing stimulus to cause a regulatory response than it takes the neurons of the nervous system to initiate a response.
hormone
________ system has a prolonged duration compared to the nervous system.
endocrine
_______ glans and other glands of the body do not have associated ducts.
endocrine
______ gland, such as a salivary gland, is one that delivers its secretions by a tube to an epithelial surface or mucosa.
exocrine
one endocrine role of the _________ is to release insulin, a hormone that triggers the uptake of glucose into cells, thus lowering blood glucose levels.
pancreas
______ cells are able to adjust the amount of insulin they secrete in proportion to the amount of blood glucose they detect.
beta cells
When blood glucose levels are too low, _____ cells secrete glucagon.
alpha cells
The _______ is a location in the brain that is an integration center between the endocrine and nervous system.
hypothalamus
The ________ produces releasing hormones that stimulate and inhabiting hormones that restrict the production of several hormones produced by the anterior pituitary.
hypothalamus
testes secrete _______, which promotes development of male sex characteristics.
testosterone
steroid hormone
ovaries secrete __________, which promotes development of female sex characteristics.
estrogen
steroid hormone
Adrenal gland secretes __________, which regulates heart rate, blood pressure.
epinephrine
nonsteroid hormone
Anterior pituitary secretes ____________, which stimulates development of eggs in ovaries and sperm in testes.
FSH
nonsteroid hormone
Pancreas secretes _______, which triggers liver to convert hepatic glycogen stores into glucose and release glucose into the blood.
glucagon
nonsteroid hormone
Anterior pituitary secretes __________, which stimulates growth.
growth hormone
nonsteroid hormone
hypothalamus secretes __________, which restricts the production of certain hormones.
inhibiting hormones
nonsteroid hormone
Pancreas secretes __________, a hormone that triggers the influx of glucose into cells, thus lowering blood glucose levels.
insulin
nonsteroid hormone
anterior pituitary secretes _________, which triggers ovulation in ovaries and the production of terstoerone by testes.
LH
nonsteroid hormone
pineal gland secretes ________, which plays a role in maintaining circadian rhythms.
melatonin
nonsteroid hormone
posterior pituitary secretes _________, which stimulates uterine contractions during childbirth.
oxytocin
nonsteroid hormone
parathyroid secretes ________, which elevates plasma calcium levels. (activates osteoclasts for reabsorption, inhibits kidneys from releasing calcium in urine.)
parathyroid hormone
nonsteroid hormone
hypothalamus secretes _________, which stimulates the production of certain hormones.
releasing hormones
nonsteroid hormone
thyroid secretes _________, which regulates growth, development, and metabolic rate.
thyroid hormone
nonsteroid hormone
_______ and ______ are steroid hormones, which allow them to pass easily through cell and nuclear membranes.
testosterone and estrogen
The _______ is a gland located behind the manubrium in adults, it is also a lymphoid organ, and it’s the place where the immune system T-cells are produced.
thymus
