NURS 208 Questions with 100%
Correct Answers
endocrine system Correct Answer: the body uses chemicals (hormones) to
communicate with each other
- requires interstitial fluid or the bloodstream for transmission
- slower response time than the neuro system
- duration of action is longer
exocrine Correct Answer: secretions through ducts into the body cavity, lumen
or surface of the body
- stomach acid, sebacous glands,
- secretes non homronal substances
endocrine Correct Answer: secrete their chemical products into the interstitial
fluid surrounding the cell and can be carried into target cell through blood
circulation
functions of the endocrine system Correct Answer: - regulates growth and
development
- maintains homeostasis (electrolyte balance)
- initiating and maintaining the reproductive system
hormones Correct Answer: chemical messengers that are manufactured by the
endocrine glands, travel through the bloodstream, and affect other tissues
,paracrine Correct Answer: chemical signal that elicits a response in neighboring
cells
autocrine Correct Answer: a chemical signal that binds to and affects the cell
that makes it
- releases and takes in the same thing they produce
classification of hormones Correct Answer: chemical composition
- peptides/proteins, amino acids, cholestrol
physical composition
- lipid soluible
- water solubles
- gases
destruction of hormones Correct Answer: - degraded into inactive metabolites
by enzymes located in the liver and kdiney
- or they are brought into the cell and is digested by lysosomes
steroid hormone transportation Correct Answer: are lipophillic and can easiuly
diffuse across surface membrans of target cells
water soluble hormone transport Correct Answer: Travel dissolved in the blood
plasma
,lipid soluble hormone transport Correct Answer: are bound to transport proteins
synthesized in the liver
two types of hormone receptors Correct Answer: - surface receptors (rapid
response)
- nucleus receptor (slow response)
control of endocrine secretions Correct Answer: - hypothalamus region (CNS to
HT)
- anterior pituitary region (HT to AP)
- endocrine gland (AP to EG)
synergism Correct Answer: combined effect is greater than the sum of individual
effects
permissiveness Correct Answer: one hormone cannot exert its effects without
another hormone being present
antagonism Correct Answer: one substance opposes the action of the other
hypothalamic-pituitary-adrenal axis Correct Answer: a hormonal feedback
system that becomes activated by stress and results in the production of cortisol
Hypothalamus Correct Answer: A neural structure lying below the thalamus; it
directs several maintenance activities (eating, drinking, body temperature),
helps govern the endocrine system via the pituitary gland, and is linked to
emotion and reward.
pituitary gland Correct Answer: pea shaped structure attached to the
hypothalamus
, - contains the anterior/posterior pituitary
anterior pituitary gland Correct Answer: AKA the adenohypophysis, secretes:
- growth hormone
- thyroid stimulating hormone
- adrenocorticotropic hormone
- prolactin
- follicle stimulating hormone
- lutenizing hormone
posterior pituitary gland Correct Answer: the posterior part of the pituitary gland
and secretes
- oxycontin (contraction of uterus and mammary glands)
- anti-diurteic hormone (electrolyte/water balance)
control of secretions by the anterior pituitary gland Correct Answer: under the
influence of the hypothalamus
- pituitary hormones are released/regulated by the hypothalamus tropic
hormones
- "releasing hormones"
tropic hormones Correct Answer: hormones that stimulate other glands to
release their hormones
