YSpermatogenesis vs Spermiogenesis
Lub hom phiaj tseem ceeb hauv lub neej ntawm txhua tus neeg muaj sia nyob yog kev yug me nyuam thiab ua kom paub tseeb tias lawv cov hom yuav muaj sia nyob yav tom ntej. Txhawm rau kom ncav cuag lub hom phiaj ua tiav, kev sib deev kev sib deev yog qhov cuab yeej, thiab gametes los ntawm cov txiv neej thiab poj niam sib xyaw ua ke los tsim cov xeeb ntxwv. Spermatogenesis yog lub ntsiab lus tseem ceeb ntawm kev tsim cov txiv neej gametes, thiab spermiogenesis yog ib theem ntawm cov txheej txheem tseem ceeb ntawm kev tsim khoom.
Spermatogenesis
Spermatogenesis yog ib qho kev tshwm sim uas thaum kawg tsim tau ntau lab tus phev ua luam dej ceev ceev los ntawm thawj cov phev hlwb. Txhua lub xov tooj tseem ceeb dhau mus rau theem sib txawv thiab thaum kawg dhau los ua cov phev ua tiav nrog tus Tsov tus tw thiab ib qho piercing acrosome. Spermatocytogenesis, Spermatidogenesis, Spermiogenesis, thiab Spermiation yog plaub theem tseem ceeb ntawm spermatogenesis. Spermatocytogenesis pib los ntawm cov diploid spermatogonium hlwb, thiab cov no ua thawj spermatocytes thaum kawg ntawm theem no tom qab dhau los ntawm mitosis. Spermatidogenesis yog theem thib ob ntawm cov txheej txheem tseem ceeb uas thawj cov spermatocytes tsim los ntawm cov kauj ruam dhau los dhau los ua cov spermatocytes thib ob tom qab dhau los ntawm meiosis - 1. Qhov thib ob theem ntawm cov kauj ruam no tsim cov spermatids haploid los ntawm meiosis - 2 los ntawm cov spermatocytes thib ob. Spermiogenesis yog ib theem tseem ceeb heev ntawm spermatogenesis qhov twg qhov kev pab cuam tshwm sim, thiab nws mus rau theem kawg ntawm spermiation. Thaum kawg, cov phev tsim tau zoo thiab ua haujlwm tau zoo yog tsim nyob rau hauv cov txiv neej kev ua me nyuam. Thawj theem ntawm spermatogenesis tshwm sim hauv cov qe ntshav thiab tom qab ntawd cov spermatids nce mus rau epididymis rau spermiogenesis. Nyob rau hauv luv luv, cov caj ces muaj pes tsawg leeg ntawm thawj cov phev hlwb hloov los ntawm diploid mus rau haploid raws li txoj cai thaum lub sij hawm spermatogenesis, thiab nws yog ib tug txheej txheem uas yuav siv sij hawm qhov chaw. Tus naj npawb ntawm cov hlwb nce vim mitosis thiab meiosis tshwm sim thaum lub sijhawm ua haujlwm.
Spermiogenesis
Spermiogenesis yog ib qho ntawm cov kauj ruam tseem ceeb hauv spermatogenesis, thiab nws yog lub sijhawm uas cov phev tau yooj yim los ntawm cov kab mob, thiab tsim cov qauv ntawm txhua tus phev. Cov spermatids tshwm sim los ntawm theem dhau los yog ntau dua lossis tsawg dua nyob rau hauv cov duab, thiab txhua tus muaj cov khoom siv caj ces nrog centrioles, mitochondria, thiab Golgi lub cev. Kev npaj ntawm cov organelles yog teem nyob rau hauv xws li ib txoj kev uas cov phev yuav nkag mus rau tag nrho cov obstacles yuav tsum tau kov yeej. Lub acrosome yog tsim nyob rau ntawm ib kawg ntawm lub cell los ntawm secreting enzymes los ntawm lub Golgi lub cev thiab lub mitochondria yog concentrated nyob rau hauv lwm yam kawg ntawm lub cell ua rau hauv nruab nrab daim. Lub Golgi complex ces npog cov condensed genetic cov ntaub ntawv thiab cov acrosome. Tail tsim yog theem tom ntej ntawm spermiogenesis, thiab ib qho ntawm cov centrioles txuas ntxiv los ua tus Tsov tus tw ntawm cov phev. Nws yog nthuav kom paub tias tus Tsov tus tw yog taw qhia rau lub lumen ntawm lub seminiferous tubule. Thaum lub sijhawm no, cov khoom siv caj ces tsis hloov pauv tab sis dhau los ua condensed thiab tiv thaiv. Cov duab ntawm lub xovtooj tau hloov mus ua ntau dua li tus xub nrog tus Tsov tus tw ntev thiab lub taub hau.
Qhov txawv ntawm Spermatogenesis thiab Spermiogenesis yog dab tsi?
• Spermatogenesis yog tag nrho cov txheej txheem ntawm cov phev tsim thaum spermiogenesis yog theem kawg ntawm tag nrho cov txheej txheem.
• Spermatogenesis hloov cov khoom siv caj ces los ntawm diploid mus rau haploid tab sis spermiogenesis tsis.
• Tus naj npawb ntawm cov hlwb tau nce siab hauv spermatogenesis, tab sis tsis muaj kev hloov pauv ntawm cov cell tom qab spermiogenesis.
• Kev tshwj xeeb thiab kev loj hlob ntawm cov phev muaj nyob rau hauv spermiogenesis, tab sis tsis nyob rau lwm cov kauj ruam ntawm spermatogenesis.
• Spermatogenesis tsis hloov cov duab ntawm lub hlwb tsuas yog hauv spermiogenesis.
