Ukuhlolwa njalo kokuma kwamaseli akhulisiwe (okungukuthi umumo nokubukeka kwawo) kubalulekile ekuhloleni okuyimpumelelo kwesiko lamaseli.Ngaphezu kokuqinisekisa impilo yamangqamuzana, ukuhlola amangqamuzana ngeso lenyama kanye nesibonakhulu isikhathi ngasinye lapho ecutshungulwa kuzokuvumela ukuba ubone noma yiziphi izimpawu zokungcola kusenesikhathi futhi ukulawule ngaphambi kokuba kusabalele kwamanye amasiko azungeze ilabhorethri.
Izimpawu zokuwohloka kweseli zifaka imbudumbudu ezungeze inucleus, ukuhlukaniswa kwamaseli ne-matrix, nokuphuma kwe-cytoplasm.Izimpawu zokonakala zingadalwa yizizathu ezihlukahlukene, ezihlanganisa ukungcoliswa kwesiko, ukuvela komugqa wamangqamuzana, noma ukuba khona kwezinto ezinobuthi endaweni yamasiko, noma zingase zibonise ukuthi isiko lidinga ukushintshwa.Ukuvumela ukuwohloka ukuthi kudlulele kakhulu kuzoyenza ingakwazi ukuhlehliswa.
1.I-Mammalian cell morphology
Amangqamuzana amaningi ezilwane ezincelisayo esikweni angahlukaniswa abe izigaba ezintathu eziyisisekelo ngokusekelwe ku-morphology yawo.
1.1 Amaseli e-Fibroblasts (noma afana ne-fibroblast) ane-bipolar noma ama-multipolar, anomumo ode, futhi akhula enamathele ku-substrate.
1.2 Amaseli afana ne-epithelial ane-polygonal, anosayizi ovamile, futhi anamathiselwe ku-matrix ngamashidi ahlukene.
1.3 Amaseli afana ne-Lymphoblast ayindilinga futhi ngokuvamile akhula ngokumiswa ngaphandle kokunamathela phezulu.
Ngokungeziwe ezigabeni eziyisisekelo ezibalwe ngenhla, amaseli athile aphinde abonise izici ze-morphological eziqondene nendima yawo ekhethekile kumsingathi.
1.4 Amaseli e-Neuronal akhona ngobumo nosayizi abahlukene, kodwa angahlukaniswa cishe abe izigaba ezimbili eziyisisekelo ze-morphological, uhlobo I olunama-axon amade amasignali okunyakaza okude kanye nohlobo II ngaphandle kwama-axon.I-neuron ejwayelekile ikhiqiza isandiso seseli esinamagatsha amaningi asuka kumzimba weseli, okubizwa ngokuthi isihlahla se-dendritic.Amaseli e-Neuronal angaba i-unipolar noma i-pseudo-unipolar.Ama-Dendrite nama-axon aphuma kunqubo efanayo.Ama-axon e-bipolar nama-dendrite angawodwa atholakala ezindaweni eziphambene zeseli ye-somatic (ingxenye emaphakathi yeseli equkethe i-nucleus).Noma ama-multipolar anama-dendrites angaphezu kwamabili.
