Koj puas tuaj yeem txhawb nqa spermatogenesis?
Raws li cov poj niam, gonadotropin tso cov tshuaj hormones, lossis GnRH, tau tso tawm hauv lub cev pulsatile, txhawb kev tso tawm ntawm follicle stimulating hormone (FSH) thiab leutinizing hormone (LH). Hauv cov txiv neej, LH feem ntau stimulates testosterone ntau lawm, thaum FSH stimulates cov phev.
Spermatogenesis chav kawm 12 yog dab tsi?
Spermatogenesis txhais tau tias yog txheej txheem uas cov phev raug tsim. … Cov phev yog txiv neej gametes uas fertilize nrog lub zes qe menyuam (poj niam gametes) tsim ib zygote. Cov phev yog tsim nyob rau hauv cov txiv neej testis. Cov phev yog tsim los ntawm cov txheej txheem hu ua spermatogenesis.
Lub sijhawm oogenesis ib lub qe qe thiab peb?
Lub qe qe uas tshwm sim los ntawm meiosis muaj feem ntau ntawm cov cytoplasm, cov as-ham, thiab organelles. … Ceeb toom tsuas yog ib lub qe loj, lossis qe, cov ntaub ntawv thaum lub sij hawm meiosis los ntawm thawj oocyte. Peb lub cev polar tuaj yeem tsim thaum lub sijhawm oogenesis.
Dab tsi yog theem ntawm oogenesis?
Oogenesis suav nrog peb theem tseem ceeb: proliferation, loj hlob, thiab maturation, thaum lub sij hawm PGCs nce mus rau thawj oocytes, theem nrab oocytes, thiab ces mus rau mature ootids [1]. Yuav muaj pes tsawg theem hauv oogenesis?
Thaum spermatogenesis qhov kawg tshwm sim ntawm meiosis yog dab tsi?
1: Spermatogenesis: Thaum lub sij hawm spermatogenesis, plaub cov phev tshwm sim los ntawm txhua tus thawj spermatocyte, uas faib ua ob haploid secondary spermatocytes spermatocytes Spermatocytes yog ib hom txiv neej gametocyte hauv cov tsiaj.
