Muaj tsib hom hlwb hauv islets ntawm Langerhans: beta cells zais cov tshuaj insulin; alpha cells alpha cells alpha cells (α-cells) yog endocrine hlwb hauv pancreatic islets ntawm pancreas Lawv tsim txog li 20% ntawm tib neeg islet hlwb synthesizing thiab secreting peptide hormone glucagon, uas elevates cov piam thaj hauv cov ntshav. https://en.wikipedia.org › wiki › Alpha_cell
Alpha cell - Wikipedia
zais glucagon; PP hlwb secrete pancreatic polypeptide; delta hlwb secrete somatostatin; thiab epsilon hlwb secrete ghrelin.
Yuav ua li cas hom cell secrete insulin?
Cov islets ntawm Langerhans yog tsim los ntawm ntau hom hlwb uas tsim cov tshuaj hormones, cov uas nquag tshaj plaws yog beta cells, uas tsim cov tshuaj insulin. Tom qab ntawd cov tshuaj insulin raug tso tawm ntawm lub txiav mus rau hauv cov hlab ntsha kom nws nkag mus rau ntau qhov chaw ntawm lub cev.
Cov hlwb twg tsim Langerhans ntawm pancreas los tsim cov tshuaj peptide insulin?
Insulin yog peptide hormone tsim los ntawm β-hlwb ntawm islets ntawm Langerhans ntawm pancreas.
Lub cell ntawm pancreas zais cov tshuaj insulin?
Insulin tso tawm los ntawm 'beta cells' hauv cov islets ntawm Langerhans teb rau zaub mov. Nws lub luag haujlwm yog txo qis cov piam thaj hauv cov hlab ntsha thiab txhawb kev khaws cov piam thaj hauv cov rog, cov leeg, daim siab thiab lwm yam ntaub so ntswg hauv lub cev. 'Alpha cells' hauv cov islets ntawm Langerhans tsim lwm yam tshuaj hormones tseem ceeb, glucagon.
Puas beta islet cells tsim cov tshuaj insulin?
Lub luag haujlwm ntawm beta hlwb yog dab tsi? Lub luag haujlwm tseem ceeb ntawm beta cell yog tsim thiab tso cov tshuaj insulin- cov tshuaj hormones lub luag haujlwm tswj cov qib qabzib hauv cov ntshav.

James ua noj puas pom cov islets ntawm langerhans?
Cov islets ntawm Langerhans tsis tau pom los ntawm James Cook, vim lawv tsis yog thaj chaw thaj chaw - lawv yog ib feem ntawm peb lub cev. Cov islets ntawm pancreatic lossis islets ntawm Langerhans yog pancreatic hlwb uas tsim cov tshuaj insulin .
Puas yog islets ntawm langerhans ib caj pas?
Islets ntawm Langerhans ua ua lub qog endocrine, thiab yog cov ntsiab lus ntawm tshooj no. Cov molecules sib txawv yog tsim los ntawm ntau hom cell ntawm cov islets ntawm Langerhans. Qhov tseem ceeb β-hlwb ntawm cov islets ntawm Langerhans tsim cov tshuaj insulin polypeptide .

Pob xiav cocoons Repawn? Cov cocoons yuav rov ua dua txhua zaus koj zaum ntawm lub rooj zaum(uas rov ua dua txhua chav tshwj tsis yog cov khoom muaj nqis).
Cov qog endocrine twg muaj cov islets ntawm langerhans?
Cov islets ntawm Langerhans, qhov endocrine ntawm pancreas, nyob ~ 4.5% ntawm qhov ntim ntawm tib neeg tus txiav, thiab lawv muaj peb qhov loj (α-, β. -, thiab δ-cells) thiab ob tug me (PP- thiab ε-cells) secretory cell hom . Cov qog twg hauv qab no muaj cov islets ntawm Langerhans?
Yuav tsum tau muab tus dev uas tsis muaj qes qes tso tseg?
Aub nrog cov noob qes qes qes qes yog qhov ua rau cov qog nqaij hlav thiab mob qog noj ntshav. Neutering raug pom zoo los tiv thaiv cov teeb meem yav tom ntej. Cryptorchid dev uas muaj ob lub noob qes tshem tawm, thiab tsis muaj lwm yam tsis xws luag, tuaj yeem ua lub neej ib txwm muaj .
