Kev tshuaj xyuas tsis tu ncua ntawm cov morphology ntawm cov kab lis kev cai (piv txwv li lawv cov duab thiab cov tsos) yog qhov tseem ceeb rau kev sim ua kom muaj kev vam meej ntawm tes.Ntxiv nrog rau kev lees paub kev noj qab haus huv ntawm cov hlwb, kuaj xyuas cov hlwb nrog lub qhov muag liab qab thiab lub tshuab tsom iav txhua zaus lawv ua tiav yuav tso cai rau koj txheeb xyuas cov tsos mob ntawm kev kis kab mob thaum ntxov thiab tswj nws ua ntej nws kis mus rau lwm haiv neeg nyob ib puag ncig ntawm chav kuaj.
Cov cim qhia ntawm cell degeneration muaj xws li granularity nyob ib ncig ntawm lub nucleus, kev sib cais ntawm cov hlwb thiab matrix, thiab vacuolation ntawm lub cytoplasm.Cov cim qhia ntawm kev lwj tuaj yeem tshwm sim los ntawm ntau yam, suav nrog kab lis kev cai kab lis kev cai, kab lis kev cai ntawm tes, lossis muaj cov tshuaj lom hauv cov kab lis kev cai nruab nrab, lossis lawv tsuas yog qhia tias kab lis kev cai yuav tsum tau hloov.Cia qhov deterioration mus deb heev yuav ua rau nws irreversible.
1. Mammalian cell morphology
Feem ntau cov tsiaj txhu hauv kab lis kev cai tuaj yeem muab faib ua peb pawg raws li lawv cov morphology.
1.1 Fibroblasts (los yog fibroblast-zoo li) hlwb yog bipolar los yog multipolar, muaj ib tug elongated zoo, thiab loj hlob txuas mus rau lub substrate.
1.2 Epithelial-zoo li cov hlwb yog polygonal, muaj qhov loj me me, thiab txuas nrog cov matrix hauv cov ntawv sib cais.
1.3 Lymphoblast-zoo li cov hlwb yog spherical thiab feem ntau loj hlob nyob rau hauv ncua kev kawm ntawv yam tsis tau txuas mus rau saum npoo.
Ntxiv nrog rau cov pawg tseem ceeb uas tau teev tseg saum toj no, qee lub hlwb kuj pom cov yam ntxwv morphological tshwj xeeb rau lawv lub luag haujlwm tshwj xeeb hauv tus tswv tsev.
1.4 Neuronal hlwb muaj nyob rau hauv cov duab sib txawv thiab qhov ntau thiab tsawg, tab sis tuaj yeem faib ua ob pawg morphological yooj yim, hom I nrog ntev axons rau cov cim txav mus ntev thiab hom II yam tsis muaj axons.Ib tug raug neuron tej yaam num ib tug cell extension nrog ntau ceg los ntawm lub cell lub cev, uas yog hu ua ib tug dendritic ntoo.Neuronal hlwb tuaj yeem yog unipolar lossis pseudo-unipolar.Dendrites thiab axons tshwm sim los ntawm tib txoj kev.Bipolar axons thiab ib leeg dendrites nyob rau ntawm qhov kawg ntawm somatic cell (qhov nruab nrab ntawm lub cell uas muaj cov nucleus).Los yog multipolar sawv daws muaj ntau tshaj ob dendrites.
