He aha ka ke koena unuhi ovogenesis o spermatogenesis?

Ma keia pepa, ke hāpai hou e līkaia Haʻalele ovogenesis o spermatogenesis, kamailio e pili ana ia lakou iho i kēia mau keʻano o ka hanaʻana. O ka holo ana, mākou e e haʻalele me ka noonoo a me ka germ keena, wehewehe i nā lāliʻi o ko lākou 'ole a me ka ho'āʻo.

Nā'ōlelo - keia mea i ka papa kuhikuhiE manaʻo o nā mea ola ma luna o mākou Honua, i mea e kokua ai i ka hoʻomau 'ana i ka' ohana laina,ʻo ia hoʻi, i ka Honua, e aole loa ia e nele. Ma ke ku, ano, i ka helu o ka mea e noho ana, o ka oi aku kānaka, e ulu ana i loko o geometrical Holomua. Ovum a sperm - ia Aloha ke keka keena o na wahine a me na kanaka kekahi me kekahi. Ka mea, o ka mea nana e e hoʻolaʻa i ka 'atikala. Ma lalo o Gametogenesis hoʻomaopopo i ke kaʻina hana o ka ho okumu ana o gametes. I ka wa e hele mai e sperm, ka mea, ua kapaia o spermatogenesis, ina ma ka hua manu keena, ke oogenesis. A pau o kēia i loko o nui au mamuli, oe e aʻo ma.

gametogenesis

Oogenesis a me spermatogenesis, i ka likeʻole ma waena o i mea ole noho pilikia, ai na mea he nui o kona hiʻona i like, hiki ke kapaia he nōhie kau - "germ laina". e pili ana i ka mea i iki hou kēia manawa.

E hoʻomaka, kālailai i ka manaʻo, ua hiki ke hoomaopopo mau huaolelo: "gamete" a me ka "Kin", i ka hope o ka Helene 'ōlelo hiki ke unuhi' ia me - "kumu". I mea literally ka manawa "germ laina" 'o ia hoʻi "kumu o gametes." Gametes - he reproductive aeee i loko o na kanaka - sperm, na wahine, - i ka hua. iho hiki ke puunaueia hoi ma ka hoohanau Gametogenesis: gametogenesis 'ia i loko o ke kino o ke kanaka, ua kapaʻia spermatogenesis, a me ka wahine o ka kino - oogenesis. Akā, iʻaneʻi, ua hele mai i ke koena unuhi mua o kēia mau keʻano o ka hanaʻana. Oogenesis hoʻomaka mua hanau hanau kaikamahine a spermatogenesis ike i na keiki, ka poe i hiki i kekahi mau makahiki, IeAUPIIe, IAa IO 12-13 makahiki.

Puberty kaikamahine

Ke kaʻina hana o ka hua manu ho okumu, 'o ia hoʻi, oogenesis ia lŘlŘ i loko o ka opu, iā puberty, a he oiaio, ua kona mua ke kahua, helu mahina no ma kahi o eiwa makahiki. Mākou e kaumaha kona wahi hou e noonoo kahua o ka puberty kaikamahine:

• 1st ke kahua - mahuahua ka ulu, he mea hihia i ka wa a ke kaikamahine e ho onui ana oi ma mua o 10 kenimika ma kiʻekiʻe, ka mea, ua noʻonoʻo ke kūmau. E like me ka rula, i keia la na kaikamahine outperform keikikane.
• 2nd ke kahua - i ka loli o nā haumāna 'īnea i' ano. About 12 makahiki kaikamahine e hoomaka ana i ka nuʻu, mai ka kiʻi o kaʻinoʻino duckling. Ua hoʻomaka e ulu umauma, hoemiia pūhaka, kupu huluhulu i loko o ka pubic wahi a armpits. Ka hola i kēia wahi Wake la i ka malamaia hua, a hoʻomaka e hoʻoholumua i ko lakou ulu ana. Soon, ke kaikamahine aoiaʻi oe i ka mea o ka mahina.
• Kolu o ke kahua - ka hope loa ke kahua. He hele mai la ma kahi o 18 makahiki. oia Ano, ua manaoia e e maopopo i hana, ka mea hiki ke paʻi olakino keiki kakou nana.

Puberty Boy

E like me mākou i olelo ia mamua, i ke kaikamahine i hana hua manu i loko o ka opu, i nā kāne a pau e hele ana i ka iki okoa. Sperm keena hoʻomaka lākou ulu wale nō ka wā e hiki 12-14 makahiki. Prior i keia kahua o ka puberty mea no hoi he loli:

• hoomahuahua i ka nui o ka penis;
• mea ulu o ka scrotum;
• e ulu ana pubic lauoho, armpits, wāwae a me ka maka.

Ma ka hiki 12-14 makahiki keiki hiki mua olalo i e nā kiʻieʻeleu, akā, he mea pono e ao aku ia oukou i kona mau makua, no ka mea, ua hiki nō i hua'ōlelo i makemake kakahiaka hāpai keiki o kona hoa. Mākou Ano, ke hoomau 'ana i ke kane a me ka wahine germ keena, kā lākou' ole, ho okumu kahua o ka hoʻonaʻauao, ka mea like a me nä mea mākou noonoo.

hua

E ka hoʻomaka me ka wahine ke keka keena, characterization o oogenesis mea, ua noʻonoʻo i ka apana uuku na hope. E hoʻomaka, ke hāpai hou 'ia e noonoo i ka' ole a me ka hana ana o ka hua.

Ka hua manu, kŘpa a nui, a me ka paa halepaahao, kona Ana hiki 170 microns, i mea nui oi kane germ aeee (i ka 70 microns). Kēlā me kēia no ia na ka mea e pono māhuaola, ma kahi e ike mākou:

• waiwai e pono ai no ka biosynthesis o ke kumuʻiʻo;
• hoʻokonukonu waiwai;
• yolk.

Keena hiki ke puunaue ma ka helu o ka hua yolks:

• ma aletsitalnye;
• politsitalnye;
• mezotsitalnye;
• oligoletsitalnye.

Mai ka negligible nui i ka loa nui, niioaaonoaaiii. Inā ka wahine hua manu, ua noonoo, ka mea hiki ke wahi e aletsitalnomu a me ka izoletsitalnomu type. I ua, malaila ka uuku o ka yolk, i hiki ke wehewehe ia e ka mea i na kanaka embryo ua hoʻomaka koke huli e gematotrofnomu 'ano o ka ai. Izoletsitalnyʻano o ia hoʻi, i ka hua manu yolk ua kōā kaulike haawi a me ka nucleus ma ka konu.

Ka hua manu iwi i ka penei:

• cytoplasm;
• Aiiay wahī;
• radiant lei.

All leho i ka aiiay papa, mai haawi aku i komo i loko o ka hua o ka oi ma mua o kekahi sperm pono ai no ka fertilization. A pau na mea e ae i wahi.

Ano, koho i ka papa hua.

• kaulike embryo ikehu;
• hoomaopopo ana i ka loiloi mua ke kahua embryo ma nutrient.

sperm

Ka mea ike i ka sperm - he kane ke keka aeea, akā, pehea 'aʻole ia hana? Mākou e kaumaha iki e nana i kēia nīnau. Helehelena gametes oe ke ike ma nā kiʻi i loko o keia pauku. I kona 'ole nō ka kēia māhele.

• poo;
• ai;
• ka waena hapa;
• huelo.

Ua piha ke poo o ka sperm nucleus, ka mea, ua iho la ka mea i hāpai i ka hereditary ike. Ma fertilization, i ka hua ae ia i. Sex o ke keiki hilinaʻi nui kaʻoi loa ma ka sperm. Inā ka mea, hāpai i ka X chromosome, ia e ia he kaikamahine, ina Y, alaila, he keiki.

Ka'ā'ī Ua hoike like me ka meaʻuʻuku hou i loko o ke alo o ka waenakonu hapa o ka sperm, keia mea i ke kuleana kuleana no kaʻeleu neʻeʻana, i ole ia ka mea makemake e hiki ole i ka fertilization.

Next hele mai i ke kino, a i produces mana no ka neʻe gametes. Ka huelo ua poe ma ka flagellum, i mea he mea nui hana - e neʻe.

Ma mua o ka helehelena o ka spermatogenesis a me ka oogenesis mākou noonoo, ke hāpai hou 'ana i kālā līkaia no ka walaʻauʻana hana o ka sperm - he hoike o ka aaiaoe mea i ka hua.

ovogenesis

E ka hoʻomaka me ke kahua o ka wahine reproductive keena, wae manawa ovogenesis a me ka ano o kela a me keia. Penei, i ke kalaʻana pae:

• ? aneii;
• ulu ana;
• maturation.

Ano, ua hiki ia ke kapaia ka mua unuhi ovogenesis o spermatogenesis i loko o ka hihia mua ua i ka muli o ka wahine reproductive aeee (oocytes), a me ka lua - ke kane (sperm). E ka i emi iho kēlā me kēia kahua o ka oogenesis.

Ma ke kahua o ka'ōlelo i loaʻa i loko o ka parenchyma o ka palapala aeee (germ) puunaue ma mitosis. Ke'ī mai, ma ka ovarian cortex, ahu iho accumulates oogonia. Ka mea, loaa:

• nā polokina;
• bipi kūpaluʻia;
• monakō koko.

Ano ka mea, ua nui okoa, mai ko lakou mua, o ka kūpono oogonia germinal nui nui, akā, me ko lakou aaiaoe no makeup mea'ālike. He nui ka e hoailona oukou i keia kaʻina i wahi ma mua o ka hanau ana o kekahi kaikamahine, i mea i loko o ka opu.

I kekahi kahua i wahi koke ma mua o ka kaikamahine i loko o ke ao nei. Kēia kahua ua kapaia ka ulu. Ano, aia no kekahi mahele o ka mitosis, no laila i hanaʻia oocytes o ka mua o ka papa. Ke hoʻohālikelike me ka oogonia ka mea, lilo uuku, akā, hou kokololio hoomahuahua i ka nui. Ano oocytes kali glitch, loaʻa ka mea, ia lakou iho ma ka granulosa iwi noho pio ana, a pau ana ka hana kūpono 'ana ke kahua o ka primordial follicle. Huina helu o na keena, ma laila nō ma kahi o elua miliona, akā, hou 'ana, e i kekahi wale no ia (ma kahi o 450).

Kolu o ke kahua (maturation) ia lŘlŘ koke ma mua o ka mua o ka malama kaikamahine. Kekahi o ka moe ko follicles kāhea mai, a mau kona? Acaeoey, i papani ai hoi i kahi o 12-13 makahiki aku nei.

spermatogenesis

Mākou i hana mua i kekahi koena unuhi ovogenesis ma spermatogenesis (ulu ana o kekahi mau germ aeee) o ka heluhelu hiki ke hoʻokaʻawaleʻia no hoi, a ua oogenesis hoʻomaka mua o ka hanau ana o ke kaikamahine, akā, i ke kaʻina hana o ka spermatogenesis - ka wā e hiki 12-14 makahiki. Mākou i hōʻike 'ano mau oko ao, a laila, ua Kû ka mea hou i ka consolidate ike.

spermatogenesis ke kahua i iki oko mai o nā kuʻina o ka oogenesis (alo aku o kekahi ka anu u). Hoomaopopo i ke kēia kuʻina o ka spermatogenesis:

• nā'ōlelo;
• ulu ana;
• maturation;
• ho okumu.

Maanei kakou e ike nei aʻo Kīwala'ō o kēia mau keʻano o ka hanaʻana, ka mea mua ekolu anuu i ka ia, ma ke kahua o ka maturation ovogenesis welau wale, a me ka sperm? Iecaianoaaiiie mau, hoʻomaka kahua o ka ho okumu.

oko ao

Oe e kokoke paʻa ai ka heluhelu i kēia 'atikala, e ho'āʻo ka mea, no ka iho - i kapa aku oko o ka spermatogenesis a me ka oogenesis. Ano ka huli mai pehea oe Makuakane me ka hana.

Ka mua koena unuhi ovogenesis o ka spermatogenesis - mea he okoa manawa hoʻomaka kaʻina. Girls gametogenesis kaʻina hoʻomaka ma fetal kūpono 'ana i loko o nā keikikāne - 12-14 makahiki.

Ka lua o ka likeʻole - ma ke kaʻina hana o ka ulu oocyte oogenesis a me ka spermatogenesis - sperm.

Ke kolu o ka likeʻole - ke ola expectancy o germ keena. Sperm ola o ka hoʻokahi haneri i hoʻokahi haneri a me ka umi mau lā (ina i ka pau kaʻina hana o ka spermatogenesis mākou noonoo, ma kahi o 74 lā), wahine keka aeea - o ka hopena o ka hoohalua loa i loko o ka ovary (12 a hiki i 40 makahiki).

Ka ha o ka likeʻole - i ka helu. Over i ka wa e ola ana, na kanaka hanau mai na haneri o ieeeea? O sperm, a me ka loa o nā kahua o ka hoʻonaʻauao a pau o ka oogenesis e ma kahi o 450 hua.

mea like

He mea i loko o ka papa o ke kākau i kēia 'atikala a kahiāuli i nā mea like a me nä mea ma waena o spermatogenesis a me ka oogenesis. Ano hou mākou generalize, ke Kû ke like me ka papa inoa o nā mea like o kēia mau keʻano o ka hanaʻana.

• Ekolu, he pono ole ka anu u (nā'ōlelo, ulu, oo ana).
• Oocytes a me spermatocytes i hanaʻia ma ka mitosis.
• I Wa ka ulu ana ma ka oogenesis a me ka spermatogenesis wehewehe aku ma ka hoomahuahua i loko o gametes.
• maturation anu u ia lŘlŘ ma meiosis.
