Chromaffin hlwb tej zaum yog qhov kev tshawb fawb ntau tshaj plaws ntawm neural crest derivates. Lawv yog ze ze rau lub paj hlwb, qhia nrog cov neurons qee cov tswv yim tsim nyog thiab yog li yog tus qauv zoo tshaj plaws los kawm cov txheej txheem ntawm neurobiology tau ntau xyoo.
Chromaffin cells yog dab tsi?
Chromaffin hlwb yog lub cev 'lub hauv paus tseem ceeb ntawm kev ncig catecholamines(adrenaline, noradrenaline) thiab endorphins, uas tau khaws cia hauv intracellular granules thiab tso tawm los teb rau kev ntxhov siab.
Puas yog chromaffin cells glial cells?
Chromaffin hlwb ntawm adrenal medulla (AM) sawv cev rau lub ntsiab neuroendocrine adrenergic tivthaiv thiab ntseeg tau tias txawv ntawm neural crest hlwb. Ntawm no, peb qhia tau hais tias coob tus chromaffin hlwb tshwm sim los ntawm peripheral glial qia hlwb, hu ua Schwann cell precursors (SCPs).
Puas yog chromaffin hlwb endocrine?
endocrine system muaj nuj nqi
… adrenal medulla yog hu ua chromaffin cells. Nyob rau hauv keeb kwm nonmammals cov qog adrenal yog qee zaum hu ua qog nqaij hlav. … adrenal medulla yog tsim los ntawm chromaffin hlwb uas muaj npe rau cov granules nyob rau hauv lub hlwb uas darken tom qab raug chromium ntsev.
Puas yog chromaffin hlwb postganglionic?
Chromaffin hlwb yog muab los ntawm embryonic neural crest, thiab yog hloov kho postganglionic sympathetic neurons Lawv tau hloov kho postganglionic sympathetic neurons ntawm lub paj hlwb uas tau poob lawv cov axons thiab dendrites, tau txais innervation los ntawm kev sib raug zoo preganglionic fibers.
