Pancreatic islets, tseem hu ua islets ntawm Langerhans, yog pawg ntawm cov hlwb hauv koj tus txiav txiav. Lub pancreas yog ib yam kabmob uas tsim cov tshuaj hormones los pab koj lub cev zom thiab siv zaub mov. Islets muaj ntau hom hlwb, suav nrog beta hlwb uas ua rau cov tshuaj insulin.
Kev ua haujlwm ntawm pancreatic islets yog dab tsi?
Cov kab mob endocrine yog tsim los ntawm cov kob me me ntawm endocrine (endo=hauv) cov hlwb. Cov Islands tuaj hu ua cov islets ntawm Langerhans. Cov hlwb endocrine no tso cov tshuaj hormones xws li insulin thiab glucagon mus rau hauv cov ntshav, uas tswj cov qib qabzib (glucose) hauv cov ntshav.
Yuav ua li cas cov tshuaj hormones secreted los ntawm pancreatic islets?
Cov tshuaj hormones tsim tawm hauv cov islets ntawm Langerhans yog insulin, glucagon, somatostatin, pancreatic polypeptide, thiab ghrelin. Cov tshuaj hormones pancreatic secreted los ntawm alpha, beta, delta, gamma, thiab epsilon cells.
Tus qauv ntawm pancreatic islets yog dab tsi?
Cov kab mob endocrine tau teeb tsa rau hauv cov islets ntawm Langerhans, suav nrog tsib lub cell subtypes: α, β, δ, ε, thiab PP hlwb uas zais glucagon, insulin, somatostatin, ghrelin, thiab pancreatic polypeptide, feem. Islet cells tsuas yog 2% ntawm cov neeg laus pancreatic mass.
Cov hlwb twg pom nyob hauv cov islets ntawm pancreatic?
Cov islets ntawm Langerhans muaj alpha, beta, thiab delta hlwbuas tsim glucagon, insulin, thiabsomatostatin, raws. Ib hom plaub ntawm islet cell, F (los yog PP) cell, nyob ntawm qhov chaw ntawm cov islets thiab secretes pancreatic polypeptide.
