Phoofolo dinama tse nyenyane tse - mefuta e le litšobotsi tsa bona

Phoofolo dinama tse nyenyane tse - pokello ea lisele tse, tse amanang ke ntho intercellular le morero bakeng sa morero o itseng. E e arotsoe mefuta e mengata, e mong le e ba tse nang le litšobotsi tse lona. Phoofolo dinama tse nyenyane tse ka tlas'a microscope a ka sheba fapaneng ka ho feletseng, ho itšetlehile ka mofuta le morero oa hae. A re ke re sheba mefuta e eketsehileng fapaneng.

Lesela a phoofolo a: mefuta e le litšobotsi

Ho na le tse 'nè tsa mefuta e ka sehloohong: connective, epithelial, ke tšohile' me mesifa. E mong le e ba bona ba e arotsoe 'maloa mefuta, ho itšetlehile ka sebaka se le tse ling tse ikhethang.

Phoofolo connective dinama tse nyenyane tse

E tšoauoa ke palo e khōlō ea ntho intercellular - e ka ba ka mokelikeli kapa tiileng. The tse fapa-fapaneng ea pele ea mofuta ona wa dinama tse nyenyane tse - masapo. Intercellular veschetvo tabeng ena tiileng. Ho na le liminerale, haholo-holo khalsiamo le phosphorus letsoai. Hape o bua ka mofuta o le mabapi ya dinama tse nyenyane tse lefufuru liphoofolo. Ho fapana ka hore lona ntho intercellular ke rekere. O ile a, le eena, arologanyediwa ka paka ya ka mefuta e kang hyaline, rekere le fibrocartilage. The atile ka ho fetisisa 'mele ke mofuta oa pele, ke karolo ea trachea e, bronchus, larynx, bronchi kgolo. Rekere lefufuru foromo litsebe tsa mahareng boholo bo lekaneng bronchus. Karolo e fibrous ya sebopeho sa discs intervertebral - ba teng ka mateano tendons le ligaments le hyaline lefufuru.

mofuta ona wa lesela e tšoauoa ka hore lisele li teng haufi haholo le mong ho e mong. The epithelium ke haholo-holo mosebetsi o sireletsang: e le bopilwe ka letlalo, ho ka betla mele bobeli ka ntle 'me ka hare. Ho tluoa tabeng ea ka mefuta e mengata: cylindrical, dikubita, ba se nang balekane-kolohantsoeng, selotlolo kolohantsoeng, ciliated, glandular, tsa mamela, seo bataletse.

Squamous epithelium e teng ka hare ho alveoli, methapo ea mali. Dikhubu e teng ka makala kang liphio, mahlo, thyroid tsoelesa e.

Phoofolo e tšohile dinama tse nyenyane tse

Ho e na le lisele tse veretenopodobnyh - methapo ea kutlo. Ba na le mohaho o rarahaneng, tse hahiloeng ho tloha namane axon (sa lehlomela la nako e telele) le dendrites (maloa lekgutshwanyane). Tsena lihlopha tsa li-cell methapo ea kutlo dinama tse nyenyane tse ya kokangana ke bona e le ka terata, matšoao a tšoaetsanoang.

Ba ka fokola' Leha ho le joalo, motho ea (kapa phoofolo) ke sitoa ho hlokomela le ho laola mesifa tsena u ithata. Next pono - striated dinama tse nyenyane tse. Ho fokotsoa haholo ka potlako ho feta pele, kaha e na le liprotheine tse eketsehileng actin le myosin, ka lebaka leo e etsahalang. Striated mesifa dinama tse nyenyane tse ke ya marapo mesifa, 'mele o ka laola hore u le mong. Ea bobeli mofuta - pelo dinama tse nyenyane tse - fapane ka hore ntseng le nyenyefala ka potlako ho feta le boreleli, o na actin eketsehileng le myosin, empa e ke ke ka natla laoloa ke batho (kapa phoofolo), ke hore, ho kopanya litšobotsi tse sa mefuta e 'meli o ile a hlalosa ka holimo. All mefuta e meraro ea lisele tse mesifa li entsoe ka lisele tse telele, tseo le tsona li bitsoa likhoele, hangata ba na le palo e khōlō ea mitochondria (organelles tse hlahisang eneji, le).
