Kedu usoro gụnyere spermatogenesis?
A nabatara ya ịmata ọdịiche dị na isi 4 nke spermatogenesis:
- Mmeputakwa.
- Uto.
- Maturation.
- Ọkpụkpụ.
Onye obula n'ime ha nwere ihe ndi ozo ma nwee ihe ufodu nke ndu. Iji malite, a ghaghị ikwu na testis n'onwe ya nwere ọnụ ọgụgụ dị ukwuu nke tubules. N'okwu a, mgbidi nke ọ bụla n'ime ha nwere ọtụtụ mkpụrụ ndụ, nke na-anọchi anya nkeji nke mmepe spermatozoa.
Kedu ihe na-eme na ogbo nke mmeputakwa?
A na-eji spermatogonia na-anọchite anya mkpụrụ ndụ nke mkpụrụ ndụ nke seminarịrous tubules. Mkpụrụ ndụ ndị a nwere ọdịdị dị iche iche, na-egosipụta nnukwu ngosipụta nke ọma na obere ego nke cytoplasm.
Site na mmalite nke oge ntorobịa, nhazi nke mkpụrụ ndụ ndị a malitere site na mitosis. N'ihi nke a, ọnụ ọgụgụ nke spermatogonia na testes dị ukwuu. Oge nke nkesa spermatogonia na-arụsi ọrụ ike na-eme bụ n'ezie ọnọdụ nke mmeputakwa.
Kedu ihe na-eto eto na spermatogenesis?
Akụkụ nke spermatogonia mgbe akpa nke mbụ na-eme ka mpaghara ahụ na-eto eto, nke a na-ahụkarị na lumen nke mkpụrụ osisi seminarịrous. Ọ bụ n'ebe a ka enwere mmụba dị ịrịba ama na ogo nke mkpụrụ ndụ, bụ nke a na-enweta site n'ịba ụba nke cytoplasm, na mbụ. Na njedebe nke a, spermatocytes nke usoro mbụ ka a malitere.
Kedu ihe na-eme na ogbo nke maturation?
Oge a nke mmepe nke mkpụrụ ndụ germ bụ nke a na-ahụ nke abụọ nke na-ebuwanye ibu. Ya mere, site na spermatocyte ọ bụla nke usoro 1, 2 spermatocytes nke 2 iwu malitere, na mgbe nkewa nke abụọ enwere 4 spermatids nwere ọdịdị oval na obere nha. Na oge nke anọ, ọkpụkpụ nke mmekọahụ- spermatozoa -takes ebe . N'okwu a, cell na-enweta ọdịdị a maara nke ọma: elongated, oval na flagella.
Maka ịmatakwu nke ọma banyere usoro ọ bụla nke spermatogenesis, ọ ka mma ịghara iji okpokoro, ma atụmatụ nke na-ele anya na-egosiputa usoro na-eme na nke ọ bụla n'ime ha.
