Flashcard 4
what does an increase in parasympathetic activity lead to in terms of glucose controlling hormone release
insulin increase
glucagon increase
associated with anticipatory stage of digestion
possible reason for low Hb1Ac when [BG] constantly high
haemolytic anaemia
site of bone growth
epiphyseal plate
where are hormones produced in pancreas
islets of langerhans
MEN
multiple endocrine neoplasia
gluconeogenesis
Amino acids -> glucose
what result would indicate haemolytic anaemia
raised bilirubin
paracrine chemicals
act local to site of synthesis
glucostatic theory
food intake determined by blood glucose
normal blood glucose range
5-10mmol/l
libido
sex drive
3 integration centres of anterior pituitary feedback control
- target cell
- hypothalamus
- anterior pituitary
what kind of collagen does bind to albumin
glycosylated
what do B islets of langerhans produce
insulin
what identifies hormones produced by anterior pituitary
endocrine
6 hormones secreted by anterior pituitary
growth hormone follicule stimulating adenocroticotrophic luteinising thyroid stimulating hormone prolactin
function of luteinising hormone
stimulates ovulation
what hormones are stimulated by presence of amino acids in the blood
insulin and glucagon
with regards to anterior pituitary what is short loop feedback
from anterior pituitary to hypothalamus
which part of the celll is preproinsulin converted to proinsulin
endoplasmic reticulum
where is thyroid stimulating hormone produced
anterior pituitary
osteoclasts
mobilise bone. digest extracellular matrix by secreting H+ ions to dissolve calcium salts
what do glycosylated proteins do that is different from normal basal lamina proteins
bind to other neighbouring proteins. rigid, cross linked proteins cannot be easily removed
