Hoʻomaʻauʻau a me oogenesis

ʻO nā kumuhana a me ka oogenesis o nā kaʻina i kūkuluʻia ai ka uluʻana, ka uluʻana, a me ka maturation o nā pūnaewele male kāne a me ka wahine. ʻO nā meaʻelua e like me ka mea like. Akā,ʻoiai, eia nō nāʻokoʻa. E nānā pono kākou i nā hiʻohiʻona o ka spermatogenesis a me ka oogenesis a me keʻano o ia mau mea.

He aha nā mea like o ka oogenesis a me ka spermatogenesis?

ʻO ka mea mua, pono e hoʻomaopopoʻia he mau kaulike like kēia o nāʻike hana. E noʻonoʻo iā lākou e like me:

1. ʻO ka hana hou. I kēia wā, hoʻomaka nā māhele mua o ka spermatogonia a me ka oogonia e puʻunaue māheleʻia e ka mīkini. Pono eʻikeʻia kēia hiʻohiʻona o kēia wā: i loko o nā kāne, hoʻopukaʻia nā pūnaewele male i loko o ke ola (mai ka wā o ke'ōpiopio ), a ma nā wāhine ua loaʻa kēia wā ma ke keʻe o ka uluʻana o ka'ōpiko (2-5 mau mahina o ka hoʻouluʻana o ka'ōpū).
2. ʻO ka ulu o ka ulu. Aia he ikaika ikaika o nā pūnaewele male ma ka nui. A laila, lilo lākou i spermatocytes and oocytes o ka 1 kauoha. I kēia hihia, nui ka nui o nā'ōcytes no ka mea ua hōʻiliʻili lākou i nā meaʻai e pono ai no ke kāpiliʻana o ke'ōpiki ma hope o ka huiʻana o ka oocyte.
3. ʻO ka papahana. Hanaʻia ma ka heleʻana o ka meiosis 1 a me ka meiosis 2. Ma muli o ka mahele mua, spermatocytes a oocytes e 2 mau kauoha, a ma hope o nā huaʻokoʻaʻelua a me nā spermatids. Pono ia e'ōlelo i hoʻokahi spermatocyte o ka order 1 ma hope o ka hoʻokaʻawaleʻana i 4 spermatids, a mai ka oocyte o 1 kauoha hoʻokahi wale nō a me 3 pola corpuscles.

He aha nāʻokoʻa o ka oogenesis a me ka spermatogenesis?

Ke kau nei i kahiʻano o ka oogenesis a me ka spermatogenesis, he mea pono e'ōlelo keʻano o kaʻokoʻa nui o kēia mau hanaʻaʻohe puka ma ka ovogenesis o nā pae he 4. ʻO nā spermatozoa wale nō ka mea e lilo i ka spermatozoa. ʻO ka hoʻomakaʻana o kēia mau pūnaewele male e hoʻomaka wale me ka hoʻomakaʻana o ka wā'ōpio i nā keikikāne.

ʻO nā kānāwai a pau o ka huahana spermatogenesis a me ka oogenesis ko lākouʻano pilikino. No laila, he laʻana,ʻo ka māheleʻole o nā pūnaewele male i loko o ka oogenesis e hoʻoikaika i ka hoʻokumuʻana i hoʻokahi hua nui nui me ka lako o nā meaʻai.

Eia kekahi,ʻo ka hoʻonuiʻiaʻana o ka spermatozoa he nui loa ma muli o keʻano o ka puaʻana o ka pua, hoʻokahi wale nō male kāne male 1. Hiki ke koena i ke ala i ka wahine.

Ke hāʻawi aku nei mākou iāʻoe i ke kiʻikuhi kiʻi no ka hoʻomaopopo maikaʻiʻana i nā hana o ka spermatogenesis a me ka oogenesis, kahi e hōʻikeʻia ai nā kumu nui o kēlā me kēia.
