Chapter 24 - Endocrine System and Pathologies Flashcards
(115 cards)
nervous and endocrine system can be referred as
neuroendocrine system
study of the endocrine system
endocrinology
secrete hormones directly into the bloodstream and are ductless glands
endocrine glands
secrete the products into ducts that open to body cavities, center of a hollow organ, or onto the surface of the body
exocrine glands
hypothalamus, pituitary gland, thyroid gland, parathyroid gland, adrenal gland, pancreas, ovaries, testes –> what type of glands of the endocrine system
endocrine glands
sudoferous glands, sebaceous glands, salivary glands –> what type of glands of the endocrine system?
exocrine glands
hormone production/secretion, metabolism regulation, stress adaptation, chemical composition/fluid volume regulation, and reproductive process regulation –> functions of what system?
endocrine system
chemical messengers that regulate physiologic activity of other cells
hormones
possess receptors for the corresponding hormone
target cells
stimulates the adrenal cortex to secrete hormones, especially cortisol
which hormone?
which gland?
adrenocorticotropic hormone (ACTH)
anterior pituitary
maintains sodium levels
which hormone?
which gland?
aldosterone
adrenal cortex
decreases urine production and raises BP
which hormone?
which gland?
antidiuretic hormone (ADH)
posterior pituitary
decreases blood calcium levels
which hormone?
which gland?
calcitonin (CT)
thyroid
helps ensure glucose, lipids, and amino acids are available for energy during times of stress
which hormone?
which gland?
cortisol (hydrocortisone)
adrenal cortex
enhances and prolongs sympathetic arousal
which hormone?
which gland?
epinephrine
adrenal medulla
development of female secondary sex characteristics
which hormone?
which gland?
estrogens
ovaries
females - stimulates estrogen production and ovarian follicle development
males - stimulates sperm production
which hormone?
which gland?
follicle-stimulating hormone (FSH)
anterior pituitary
increases blood glucose levels
which hormone?
which gland?
glucagon
pancreas (alpha cells)
stimulates protein synthesis for muscle and bone growth, maintenance, and repair
which hormone?
which gland?
growth hormone (GH)
anterior pituitary
decreases blood glucose levels
which hormone?
which gland?
insulin
pancreas (beta cells)
females - stimulates the release of estrogens and progesterone, ovulation, and development of the corpus luteum
males - stimulates testosterone production
which hormone?
which gland?
luteinizing hormone (LH)
anterior pituitary
increases skin pigmentation
which hormone?
which gland?
melanocyte-stimulating hormone (MSH)
intermediate pituitary
controls biorhythms or body’s 24-hour cycle
which hormone?
which gland?
melatonin
pineal
enhances and prolongs sympathetic arousal
which hormone?
which gland?
norepinephrine
adrenal medulla
