Chiyambi cha kukulanso miyendo ya munthu

Zitsanzo za kubadwanso zachuluka mu zinyama: abuluzi ndi salamanders amakulanso miyendo ndi michira nthawi zonse, momwemonso ndi starfish. https://blogs.scientificamerican.com/guest-blog/regeneration-the-axolotl-story/

Planaria ndiwodziwika bwino (ndipo mwina sakufuna) kutenga nawo gawo pazoyeserera pakukulitsa mitu iwiri (https://www.youtube.com/watch?v=roZeOBZAa2Q). Osati kuti tikufuna kukhala ndi mitu iwiri, koma bwanji anthu sangathe kukulitsanso ziwalo, mikono kapena miyendo yotayika? 

Ngakhale kuti ma cell ena m'matupi athu amatha kubadwanso - machiritso a khungu, matumbo athu, chiwindi chathu - amatero mochepa. Chikhulupiriro chapamwamba mu biology ndi chakuti momwe selo kapena minofu imagwirira ntchito mwapadera, m'pamenenso imachepa mphamvu yake yokulirakulira. Pamene anthu akukwera m'makwerero achisinthiko, maselo athu ambiri adutsa posiyanitsira: mutha kukulitsa tsitsi lanu kumbuyo, koma chala chodulidwa chimakhala chitsa.

Chidziwitso chathu chowonjezereka pama cell stem-ndi kuthekera kwawo kusiyanitsa-- zapangitsa kuti kusinthika kwa minofu kukhale kotheka. Ndipotu, Dr. Levin mu ntchito yake watsimikizira kuti zizindikiro za bioelectric zimayambitsa kusiyana kwa maselo ndi minofu. Werengani za kupambana kwake mu kusinthika kwamagetsi kolimbikitsa kwa amphibians: https://www.popsci.com/body-electrician-whos-rewiring-bodies

Dzanja kapena mwendo ndi kuphatikiza kodabwitsa kwa khungu, fupa, minofu, minyewa ndi mitsempha yomwe ili ndi ntchito zosiyanasiyana. Chinyengo ndikupeza zizindikiro zolondola kuti zilimbikitse selo lobadwa bwino lomwe likukulirakulira m'mapangidwe awa.

Zizindikirozi zikatsegulidwa, chopinga chotsalira ndi momwe tingapitirizire ndondomekoyi - ndipo izi zimaphatikizapo kuthana ndi machiritso athu obadwa nawo. Thupi likawona kuvulala limayesa kutseka malo aliwonse owonekera potaya kolajeni m'dera lomwe pamapeto pake limakhala zipsera. Izi zitha kukhala zothandiza potseka chilondacho, koma zimapangitsa kuti malo ovulalawo akhale osagwira ntchito.

Njira yothetsera vutoli ndikusunga malo ochiritsa omwe ali m'malo a hermetic momwe amathandizira kukula kwa minofu. Kusunga nthambi yomwe ikukula mu 'kusamba kwa michere' iyi kumathandizira kuchira ndikuyiteteza ku matenda kapena kuvulala.
