Muaj peb yam subtypes ntawm spermatogonia hauv tib neeg: Hom A (tsaus ntuj) cov cell, nrog cov nuclei tsaus. Cov hlwb no faib los tsim Hom B . hlwb. Hom B . cov cell, uas faib ua kom nce mus rau thawj spermatocytes.
Yog li ntawd, qhov txawv ntawm spermatogonia thiab spermatocytes yog dab tsi?
Lub ntsiab qhov sib txawv ntawm spermatogenesis thiab spermiogenesis yog qhov ntawd spermatogenesis yog tsim cov phev hlwb thaum spermiogenesis yog qhov maturation ntawm cov spermatids rau hauv cov phev hlwb.
Tsis tas li ntawd, spermatogonia puas raug mitosis? Lub sijhawm ntawm lub sijhawm spermatogenesis Cov no yog Hom A spermatogonia . Cov hlwb no raug mitosis : ib ntawm tus ntxhais hlwb txuas ntxiv cov khoom lag luam ntawm hom A spermatogonia , lwm qhov dhau los ua hom B. spermatogonia . Cov kev faib no thiab lawv cov ntxhais cov ntxhais tsiv mus rau lub lumen.
Ib yam li ntawd, koj tuaj yeem nug, qhov ua haujlwm ntawm spermatogonia yog dab tsi?
Spermatogonia yog cov hlwb sib npaug uas nyob rau hauv kev sib cuag nrog cov hauv qab daus membrane ntawm cov tubules seminiferous. Lawv yog cov qia hlwb ntawm lub cev, faib los tswj lawv tus kheej cov lej thiab tsim cov hlwb uas pib ua cov txheej txheem ntawm kev loj hlob mus rau spermatozoa.
Peb theem ntawm spermatogenesis yog dab tsi?
Spermatogenesis : txheej txheem los ntawm cov qia hlwb txhim kho mus rau spermatozoa paub tab. Muaj peb theem : (1) Spermatocytogenesis (Mitosis), (2) Meiosis, thiab (3) Spermiogenesis.
