Palapala, a me ka hana nui ana o ka sperm aeea

Hāpai keiki i loko o ka wahine meaola ia lŘlŘ kūpono ma ka hoʻokuʻi pū o nā gametes. Kekahi o ia ua kapaia ka sperm, a me ka mea 'ē aʻe - i ka hua. He aha ka i ka nui o ka sperm? He aha nā hiʻona hoʻomaopop 'ana i germ aeea? Ke sperm mea okoa mai ka hua? Pane i kēia mau nīnau a pau e e loaʻa.

Male reproductive kahua

kumu kāki i hana i loko o ke kino 'elele o ka hapalua ikaika o ke kanaka hana i kekahi mau glands a me nā loko:

• hoʻi me nā appendages;
• vas deferens;
• prostate;
• seminal vesicles;
• bulbourethral gland;
• scrotum;
• penis.

A pau o ka mea ma luna collectively haawiia keia i like me ka kane reproductive nenoaiu. Ua hana sperm. Kēia manawa pili ia i ke kane ke keka keena hiki ke fertilization. Ma unprotected anal sperm haʻalele i ke kane moe'ōnaehana, a komo i ka wahine kino.

I ka mana o ka hana kūikawā keena

Sperm - he 'ole i loko o a ka aaiaoe ike ua kakauiaʻi maluna kanaka. Oihana ma ka hana kūikawā keena o ke kino kekahi kāne:

• ka hooholo ia ana o wahine wahine'āpana (nui a me ka 'ole o ka sperm o ke kanaka e leie aku ia ia, e lanakila i ka likeʻole nā pilikia);
• anal i loko o ka wahine germ keena, i kapaia hua;
• hoololi ana i ka aaiaoe mea.

Ua mea waiwai 'ana i kumumanaʻo ana i intimacy i loko o ka wahine o ka kino loaʻa sperm. Ua ninoieo o seminal loli a me ka sperm keena kaulia ana i loko o laila. Male germ keena ma semen kekahi he nui dala. Akā, i ka oo hua manu i loko o ka wahine kino mea e kū hoʻokahi. hiki ole wale kekahi kane germ keena hana a pau o kona hana. A nui kūlana i loko o ka mea hoʻokani ma ka nui a me ke kinona o ka sperm.

Ka 'ole o ka spermatozoon: ke poo a me ka'ā'ī

No ka mea kane anal aeee i wehewehe aku ma kekahi mau 'ano, a ua hoakaka no ka hiki e keʻoni aʻe, ka fertilized Kepakailiula. Sperm mea he'ololaha 'ole me ka lōʻihi flagellum. He aha ka ka 'ole o ka halepaahao? Pela, ke sperm ua poe e ekolu eiiiiiaiou:

• poo;
• ai;
• huelo.

Head - keia hapa ka'ololaha o ka sperm. Ma kona luna o ka acrosome. No laila, ka mea i kapaia o vesicle me kūikawā ka mahuaola e pono ai no ka ovum anal ma ka aiiay wahī. Ke poo hoi be he Kernel. Ua mālama i ka hapalua o ka helu ana o ke kane aaiaoe 'ike (DNA). Kekahi ke keʻena o ke poʻo - ka centrosome. Ua kōkua ai i nā ka neʻeʻana o ka huelo.

I ka lua o ka aoao o ka sperm - ia ka'ā'ī. He He fibrous wahi i hoʻohuiʻia ke poʻo, a me ka huelo. Kēia 'ole ka loa'ōlewa. Kēia hiʻona mau hiʻohiʻona nō i ka neʻeʻana o ka sperm. Me ke kohoʻia o ke poʻo oscillates mai kēlā me kēiaʻaoʻao.

Ka 'ole o ka sperm huelo

Ma mua o hōʻike no ka nui o ka sperm aeea, ia mea pono e noonoo ia i kekahi hapakolu - he flagellum. Ua Ua kapaia ka huelo. Ua nā kekahi mau pauku:

1. Kuwaena. He ka thickest loa o ka sperm huelo. Ua loaʻaʻoni iho mitochondrial, ahu iho i produces i ka ikehu no ka neʻeʻana o ke kane germ aeea.
2. Aliʻi. Kēia hapa o ka sperm ninoieo o microtubules. Lākou anuanu mawaho, ahu iho uhi na olona, a me ka aiiay wahī.
3. Ka pau. Ma keia hapa o ka aiiay vaginal sperm a anuanu olona, e thinner. Ka penaʻana mea he wiwi aeeaʻili lahilahi.

A familiarized me ka 'ole o ka mea hope loa o ka sperm, ka mea hiki e manao ia ka huelo tapers i nā, mai kona kumu a hiki i ke kihi. Kēia hiʻona i nā bicheobraznye ana o ke kane reproductive keena like kou holo i loko o ka wahine wahine'āpana ma ka huli ana i ka ovum.

Ana sperm

Male germ aeee mea uuku loa. I ka nui o kanaka sperm like penei:

• keena huina pau loa - ma kahi o 55 microns;
• poo kiekie - 2,5 microns, laula, - 3.5 mm o, lōʻihi - 5.0 microns;
• cervix sperm - ma kahi o 4.5 microns ma ka lōʻihi;
• huelo lōʻihi - 45 m.

Male germ aeee hiki ole ke ike i ka maka kapa ole. I ka nui o ka sperm hiki ke ike ma lalo o magnification. It kekahi manawa, i hana ai Leeuwenhoek. I ka 1677,ʻo ia i ho'ākāka 'ia i ka spermatozoa. Nä känaka 'epekema, ua i ka loaʻa,'ōlelo i kēia mau keena i komo i loko o fertilization. Naʻe, ke kaiāulu kanaka, ike e ole ia seriously. About 100 makahiki, ua manaoio kānaka sperm parasitic microorganisms.

Ke kahua o ke kane germ keena

Ma ka ninau e pili ana i ka nui sperm pane. Ano ka mea, Ua pono, e hoomanao i ke ano mau keena e hana ai. Sperm keena e ku oe a oʻo ma kūikawā glands kapaia na testes. Mau hale i aia i loko o ka scrotum. Ka mea, iloko o ka nui helu o seminiferous tubules, hoalaala ia me ka kūikawā aeee (spermatogonia). E like me ka mea kane anal aeee i hana 'aneʻi? Kēia kaʻina hoʻomaka i puberty:

• spermatogonia māhele;
• like me ka hopena o ka hou keena;
• oʻo sperm ma ka Sertoli keena, pee i kekahiʻano o ka mahuaola.

Ke kaʻina hana o ka ho okumu ana o ke kane gametes ua kapaia spermatogenesis. Ua paʻakikī. Ma ke kahua o ka iniiaiie spermatocytes kaʻina 'aʻole e hoʻopau, no ka mea, na keenaʻikeʻia hoʻomaopop' ana i loko o ka piha 'ia paha o nā chromosomes. Eia, i kēia mau keena undergo meiosis. E like me ka hopena, malaila spermatids i ka hapalua o ka helu ana o chromosomes. Keena i nā ulu a me ka hoʻomōhala. I ka hopena o ka oʻo sperm.

Honua o kāne germ keena

i ka hana a me ka nui o ka sperm aeea E noʻonoʻo pono, e pono e familiarize oe iho me pehea ka ke keka aeea Pńk'pika. Ke sperm mea i loko o ke kane kino, ua AEeOEXAaI. Ka mea, passively holo i loko wahine apana. Honua huelo he mailuilu haalele. ʻeleu sperm lilo iā ia ma hope o noho i loko o ka wahine kino. Lākou māmā e kela aku kona nui ma mua o 30 knm no hora.

Ma hope o ejaculation i loko o ka wahine o ka kino loaʻa oi ma mua o 300 miliona sperm. Ka hapa nui o ia pepehi i loko o ka vagina aie a hiki i ka noho lakou malaila kaiapuni. Kekahi kane germ aeee ke kū i ka cervical Canal. Naʻe, i kēia māhele o ka Track huli, e hele, i nā mea a pau sperm. Keʻakeʻa nei no ia noho cervical mucus.

Sperm hala ka cervix, i loko o ka haule ana uterus. Wednesday ma ka maloko hui, kēia mea conducive ke kane germ keena. Mai ka opu ka mea, e hoouna aku ai i ka fallopian paipu, kahi fertilization i wahi. Haʻawina ua hoike ia wale he mau tausani sperm hele i kēia ala.

Ke ola kīkoʻo o ka sperm

aeea ho okumu mau no ma kahi o 74 mau lā. Maturation a me kā lākou e hooholo ia ma ka epididymis a me vas deferens e lawe ma kahi e 26 mau lā. Ua paipai ia sperm ke koe i kekahi manawa loa i loko o ke kanaka i ka ke kino. Ke kahua Ua okoa ma hope ejaculation. Ke sperm germ keena noho hana ole oi ma mua o ka lā (lōʻihi like 'ole o kēia wā hilinaʻi nui ma mawaho kumumea like me Ambient ana wela, i ka nui o ka malamalama, humidity).

Ma ka wahine ola kīkoʻo i e okoa. Inā i ka mämä holo o ka neʻeʻana o ka sperm e loli ai i ka nui, ka lōʻihi like 'ole o ke ola ana o keia kuokoa. No ka laʻana, ma ka vagina kane germ aeee i make ma hope o 2 HR. I ka uterus a me ka fallopian paipu 'ia mea oi conducive ke sperm. Here ka mea, hiki e mai i 5 mau lā ma kaʻeleu moku'āina ma ka huli a kali Kepakailiula.

E like no sperm me ka hua

Ma ke kane kekahi manawa hana a oʻo, hou keka keena. Me kela a me keia hana o ke keakea ole i ka sperm ua hookuu, i loaʻa i ka nunui nui o ka sperm. Akā, i loko o ka wahine o ka kino oʻoʻana wale nō hoʻokahi keka aeea no kekahi menstrual kalapona (ka hola 28-30 lā).

Ano ka mea, Ua pono, e hoohalike i ka nui o ka hua a me ka sperm. Male gamete, e like me ka olelo maluna, o ka moku 'ole. Ka hua manu Ua pau okoa. Kona nui i ka ÷ 0,15 a 0,25 mm o. I ke kumukuai o 'ana i kumumanaʻo mea i ua paa i ka hua. Eia hou kekahi, ka mea i heʻano pōkole ola expectancy. Ma hope o hookuu mai i ka ovary a me ka fallopian Tube ma ka hui 'ana me ka mea hiki ia ma kahi o 24 hola. Inā fertilization Aʻole ole ana, o ka hua make.

Ma ka hopena, e pono ke kūʻai 'ana i kumumanaʻo ana i ka nui o ka sperm aeea mea uuku loa. I loko nō o kēia, ka mea, he nui ka papa, a he loko o ka fertilization o ka hua. Eia naʻe, e hoʻokō i keia la e hiki ai i nā mea a pau sperm. Noho i loko o ka wahine kino, e hele lakou ma maoli wae. Nawaliwali a me ka mea hewa hale keena make loa koke me ka hiki ole i ka uterus. Mea e ae wale mai i manawa e kiʻi ai i ka pahu hopu. Wale nō ka wikiwiki a me ka K'lauea sperm, piliwaiwai na nā pilikia a pau i loaʻa komo iloko o ka hua, a hoʻouka hou aku au ia i ko lakou aaiaoe ike.
