Ndi minofu mantha Kodi

Mantha minofu (NT) akuti ndi chinthu structural ya ubongo, zochokera ku ubongo ndi kutha molekezera mitsempha. Ngati tikulingalira Kapangidwe ka mitsempha minofu, mwina kudziŵika kuti tichipeza maselo mitsempha wotchedwa manyuroni kugwirizana maselo chowonjezera (neiroglii), ndipo ulusi ndi mapeto mu mulinso Mitsempha ndi minofu connective.

Kusinthika kuchokera ectoderm ndi, NT ndipamene chapakati mantha dongosolo. Iwo maselo ndi kusonkhanitsidwa m'magulu, motero, pali nkhani imvi, ulusi ndi kusonkhanitsidwa mu mitolo, n'kupanga woyera olimba.

minofu mantha amakhala ndi conduction ndi irritability. Choncho kulowa maselo kukondoweza akusinthika mu nyemba, zomwe adzapatsidwa ku ziwalo zogwirizana, zimakhala kapena minofu. Maselo HT ndondomeko ndi sitolo zambiri, ndipo akhoza kupeza izo pamtima likafunika.

minyewa A imakhala ndi phata ndipo cytoplasm yozungulira (perikaryon), kumene mitochondria, ribosomes, golgi zovuta, etc. Nissl mankhwala. Kuchoka kwa icho akuwombera, amene ankaimira ndi mitundu iwiri.

1.Dendridy - pa iwo patsogolo ndi kunditumiza ku thupi selo. Iwo ndi kutalika kwa 0.2 microns.

2. neurite (axon) - zimachitika pomwepo ndi kunditumiza ku thupi selo. Izo ukutha ndi nthambi kupanga kugwirizana ndi manyuroni ena kapena zimakhala limba.

Tikumbukenso kuti maselo mitsempha titha kuchita zikhumbo mosamalitsa mu njira imodzi.

Mitsempha minofu ali mitundu itatu ya maselo mitsempha:

1.Afferentnye - kubala zimachitika m'badwo.

2.Effektornye - kupangira minofu akuluakulu kanthu. Zikuphatikizapo manyuroni galimoto ndi maselo neurosecretory (amene amasamalira kusinthika).

3. Associative - kugwirizana mawonekedwe pakati pa maselo mitsempha.

Mitsempha ulusi amaimira ndondomeko manyuroni atazunguliridwa lemmotsitami. Iwo unmyelinated ndi myelinated. Malinga dongosolo awo, iwo ali m'gulu kapangidwe ka mbali ya ubongo.

Mitsempha ulusi kutsirizitsa zipangizo wapadera, wotchedwa molekezera mitsempha ndi awo chikugwirizana kudzera nsalu CHIKWANGWANI ndi zinthu zosiyanasiyana. Mapeto a mitundu iwiri: affectors ndi synapses. The malemeredwe woyamba ikuchitika pa nsalu CHIKWANGWANI, wachiwiri M'malo mwake, CHIKWANGWANI ndi kumtunda nsalu.

Komanso, minofu mantha ali glia, ndiye kuti, ndi gulu la maselo amene ali pakati manyuroni. Maselo amenewa ntchito monga zodzitetezera secretory, kulekanitsa, ndi thandizo trophic. Iwo nawo pogwira malemeredwe ulusi pa kusinthika awo ndipo alibe.

Choncho, kuganizira ntchito ya minofu mantha, ndi zotsatirazi: kupanga ndi conduction wa chizindikiro magetsi, mafunsidwe ndi kusunga pokumbukira zinthu zina, mbali mu mapangidwe khalidwe, kaganizidwe ndi maganizo.

Choncho, HT ndi apadera kwambiri mtundu wa nsalu, wopangidwa mwa maselo, ulusi mapeto ndi glia. maselo amakhala kuzindikira likuyabwa kwambiri, kupoletsa nyemba zina, kenako zimafalitsa iwo. Chifukwa minofu imeneyi kumatanthauza kusakanikirana ndi, malumikizanidwe, anatengera ziwalo zonse, zinthu zimakhala m'thupi la munthu.

Tikumbukenso, pamene minofu mantha ali matenda, kuvutika zinthu zonse m'gulu kapangidwe kake. Pankhaniyi, pangakhale njira pathological, mwachitsanzo, kutupa, chotupa kapena kupunduka zina zimene zingakhudze wamanjenje dongosolo. Change kapena imfa ya zinthu mu NT ndi kulipidwa ndi kukula kwa minofu connective kapena chitukuko cha cysts.

Tikumbukenso kuti mantha dongosolo lonse wapangidwa ndi minofu mitsempha, ndi mwa zomwe kuchita njira zonse mu thupi la munthu.
