General medical Flashcards
endocrine glands
duct?
where are effects?
ductless
secrete hormones into circulation resulting in widespread effects
exocrine glands
duct?
where are effects
release chemicals through duct and have localized effects
Hypothalamus location
deep in cerebrum of brain
Pituitary gland nickname
master gland
anterior pituitary gland hormones
adrenocorticotropic hormone
thyroid stiimulating hormone
follicle stimulating hormone
luteinizing hormone
prolactin
posterior pit gland hormones
antidiuretic hormone
oxytocin
diabetes insipidus features
large output of urine
inadequate adh secretion
thyroid shape and location
butterfly shape in neck anterior to inferior larynx
parathyroid location
four small glands located on posterior lateral surface of thyroid
thyroxine t4
stimulates cell metabolism
made in thyroid
triidothyronine t3
stimulates cell metabolism
made in thyroid

increases blood calcium level
antagonist to calcitonin
made in parathyroid
