Somatostatin yog cyclic peptide paub zoo rau nws cov kev tswj hwm muaj zog thoob plaws hauv lub cev. Kuj paub los ntawm lub npe ntawm kev loj hlob hormone inhibiting hormone, nws yog tsim nyob rau hauv ntau qhov chaw, uas muaj xws li lub plab hnyuv (GI) ib ntsuj av, pancreas, hypothalamus, thiab central nervous system (CNS)
somatostatin secreted los ntawm qhov twg?
Somatostatin yog zais los ntawm cov hlwb tawg nyob hauv GI epithelium, thiab los ntawm cov neurons hauv lub paj hlwb enteric. Nws tau pom tias inhibit secretion ntawm ntau lwm yam GI cov tshuaj hormones, suav nrog gastrin, cholecystokinin, secretin thiab vasoactive plab hnyuv peptide.
Somatostatin tsim nyob rau hauv pancreas nyob qhov twg?
Somatostatin tom qab tau pom tias tau nthuav dav thoob plaws hauv nruab nrab paj hlwb thiab tshwm sim hauv lwm cov ntaub so ntswg. Hauv cov txiav, somatostatin yog tsim los ntawm cov delta hlwb ntawm cov islets ntawm Langerhans, qhov uas nws ua haujlwm los thaiv kev tso tawm ntawm ob qho tib si insulin thiab glucagon los ntawm cov hlwb uas nyob ib sab.
Somatostatin nyob qhov twg hauv hypothalamus?
Somatostatin yog tsim los ntawm neuroendocrine neurons ntawm ventromedial nucleus ntawm hypothalamus Cov neurons no rau qhov nruab nrab eminence, qhov twg somatostatin raug tso tawm los ntawm cov hlab ntsha neurosecretory xaus rau hauv hypothalamohypophysial system los ntawm neuron. axons.
cov hlwb somatostatin nyob qhov twg?
Somatostatin-muaj cov hlwb D pom thoob plaws hauv plab hnyuv thiab txiav(309).
