Where sperm ua hana: pehea a me kahi e hoʻonaʻauao

Men i ole e emi 'ike ma mua o nā wāhine. No laila, i kekahi o ia mea hoihoi i loko o ka mea ka kino iho, a oi loa aku hoi kona loa nui nā loko. Wiwo ole ma keia hihia e na kumu, a me ka poe i koe e hana i ka heluhelu ana i koi 'ia moʻokalaleo. Ka mea nui wale nīnau i: Where sperm ua hana? Pehea i ka mea, nana e like? Pehea na ola? Pehea e neʻe? E ka ho'āʻo e haʻi aku iā lākou i loko o ia i kekahi ala e ia mea akaka i na kanaka a pau.

ka wehewehena

Mua mai la ka ninau, ma ua hana sperm, kekahi pono ike i kona ho. Sperm - keia germ keena o nā holoholona a me nā kānaka. Nō kāu, e hiki ke neʻe 'Imi, i mea e pōʻino ka mea e hiki i ka hua, a fertilize ia i kēia mau keena.

E like me hoʻohālike au i ka wahine germ keena, sperm aeee i uuku, nimble, a ma ka mea hookahi manawa i loko o ke kino oʻoʻana he nui helu (i kū'ē i ka hua manu, a kekahi mea i ka lei o ke kanakolu wahine endocrine nenoaiu).

Ke 'ole o kēia germ aeea Hōʻike i nā holoholona a me nā fungi i ka like kūpuna - he hookahi-aa? Meaola. Mea maʻa mau, i kekahi kane keka keena, a hiki i ka mea kanu, i kapaʻia ka sperm, eia nae pili ia ia, a me ka ho'ākāka 'ana o "sperm" a me ka anterozoidy.

Sperm aeee i na holoholona

Oddly lawa, akā, i nā holoholona i ole mea okoa mai kekahi kanaka i loko o ka ninau o ka 'ole a me ka hana o ka germ keena. Where sperm e hana? Pehea mai ka mea nana? He loaʻa kekahi kumu loli?

Normal holoholona sperm mai i ke poo, he palapala kuleana, a me ka huelo ( 'ole flagellum). Ke poo, mea maʻa mau, o ka Kernel, i ka hapalua o ka helu ana o chromosomes. Ma waho aʻeo i ka aaiaoe 'ike i loko o ka poo i nā'ūhū no ka hoʻokomo' ia 'ana o ka hua, a me ka centriole. Ka palapala hapa o ka ia ai, aia no he nui mitochondrion, a hoakaka i ka ikehu a me ka malama kona flagellum ana.

'Ia mai ka hāpana i na poe ma ka luna o kekahi mauʻano o ka aquarium iʻa nona ka sperm i mau flagella. E like me ka mea pili i ka crustaceans (ka mea, i e ekolu a oi "huelo" mai ka germ aeee). Akā, roundworms evolution hihia lakou a pau ma ka motile keena - aole no he cilia a flagella a puni kona kino. Sex keena o kēia mau holoholona i ka ea aeea pa e leie aku oe, e ka hoʻokele hoʻohana 'ana i prolegs. Ma newts ma sperm keia fin. Akā, ua likeʻole,ʻaʻole wale nō i loko o ka huelo, akā, i loko o nā poʻo. Inā ka mea, ellipsopodobnye kekahi kanaka, e kaʻiole a me nāʻiole ke kaena kryukopodobnoy palapala.

Ke Ana o reproductive aeee i loko o na kanaka, ua uuku loa - mai ka umi a hiki i na haneri o micrometers. Oia like ka mea, e hana ana me ka nui o ka makua.

Puka o ka sperm

Muaʻepekema Ua noʻonoʻo i ka nīnau, "Auhea ka ka sperm hua?", Lakou i ka hāʻuleʻana i loaʻa i kūikawā keena komo i loko o ka'ōlelo o ke kanaka a me ka holoholona. A me ka nui o ka 'ole o ke ola nā'aʻaʻa i mea uuku manaʻo.

ʻOiʻenehana ma ka 'epekema mai ai i loko o ka waena o ka makahiki kenekulia, ka wā Antoine Dutchman Leeuwenhoek invented ka microscope, a nana aku la i aku la ia ia kekahi mau mea: pollen, lau a me petals o nā mea kanu, kanaka a me ka holoholonaʻili, a oi. I ka 1677, ka mea i hele mai e germ keena. He hōʻike i ka hua manu a me ka sperm, i aku la ia i ho'ākāka 'ia e like me "seminal holoholona."

Like kekahi nä känaka 'epekema, Leeuwenhoek mua i nā mea a pau i ka ho okolohua ma luna ona, no laila, i ka mua kanaka sperm ua oleloia ua hiki aku, a wale ma hope o nā holoholona. Ka manaʻo i kēia mau "holoholona" e komo i loko o ka hapai ana, hele koke mai i ke poʻo o Antoine ka, i aku la ia i ole ole i ka hai aku i ka Beritania scientific kaiāulu.

Akā, Ua hooleia keia kuhiakau, a ua manaoia he haneri makahiki parasites sperm i loko o ke kanaka i ka ke kino, aole hoi i kekahi mea e fertilize i. Wale nō i loko o ka kakahiaka umikumamaiwa kenekulia, ka Italia Spallanzani hoao iho la ia i kaʻoiaʻiʻo o kēia kumumanaʻo.

'ole

Inā 'oe e ole lawe i loko o ka nui o ka lōʻihi o ka flagellum, ka sperm o ka uuku aeea i loko o ke kino o ke kanaka, ma kahi o 55 micrometers. Mau Ana uuku ae ia e neʻe koke aku i loko o ka lua o ka uterus, a hiki aku i ka hua.

I mea e e hiki emi mai i loko o ke kahua o ka sperm, ka mea, undergo i ka moʻo o ka loli ':
- ka nucleus i oi ke kaumaha o ka condensation o aaiaoe mea;
- cytoplasm ua kaawale i loko o ke kaawale "cytoplasmic droplet";
- eia wale ka poe organelles i mea e pōʻino ai i ka halepaahao.

1. Ke poo o ka sperm aeea i ke kinona o ka ellipse, he flattened laterally. I kekahi manawa ka mea, hiki e concave ma kekahiʻaoʻao, a laila, ua hiki ke kamailio e pili ana i ka palapala, kūnihi ke gula. I ke poʻo i:
   - i kāna mau 'ōlelo me ka haploid' ia paha o nā chromosomes. He pono ia ma hope o ka hoʻokuʻi pū o nā keka keena huina dala o aaiaoe 'ike ua like no ia o ka somatic keena, a me ka fetus e ole ola paha, e loaʻa deformities. No ka mea, o ka "contraction" o ka chromatin ikaika ia mea AEeOEXAaI a me ka hiki ole synthesize RNA.
   - acrosome - ua evolutionarily Hoʻololi 'Golgi i hoʻomākaukauʻia, ka mea i pono, e hōʻoia' ana i ke poʻo o ka sperm ke komo i loko o ka hua.
   - centrosome - organelle, a kākoʻo i ka "halepaahao iwi" a me ka hoʻolako i ka neʻeʻana o ka huelo.
2. Na waena hapa paha o ka'ā'ī - ua hou ma waena o ke poo a me ka huelo. He na mitochondria, a paka ikehu no ka neʻeʻana o ka flagellum.
3. Huelo a flagellum - he lahilahi hoʻoneʻe hapa o ka sperm. Hana he rotational pānaʻi mai noi, hiki i ka halepaahao, e hiki i ka pahu hopu.

kuleana pili i

Ka papa hana a me ka spermatozoa ke kina ole ho okumu ua pili loa aku i konaʻoihana. A me ka mea nui o ia mau mea - he hana anal i loko o ka hua a me ka fertilization. E hana i kēia kuleana pili i, ke ano maoli i hoomakaukau ka hoʻoneʻe, nuipa a me ka Nine Inch "attractiveness" o ka sperm.

Male a me ka wahine meaola manao no nā'ōlelo o ko lākou mau ano, no laila, ka mea i hana maʻalahi kāohi, chemically a genetically. Inā he kanaka i mālama i kona ola,ʻaʻohe inoʻano, i ka manawa e hana i nā mea a pau vaccinations (oi loa mumps), kona germ aeee e e makaukau e hana kona hana i kekahi manawa.

ka noi

sperm ho okumu i ka na kanaka mea ku pono, i waena o Alia, a me ke kahua o ka flagella, i kokua aeee e neʻe. Iloko o ka neʻeʻana o ka gamete ua ke ka ao ka puni kona iho (axis) i ka mämä holo o ka 0,1 millimeters no kekona. Ka mea, Ua oi aku mamua o kanakolu kenimika no ka hora. Ka mea, Pono, e uhi i ka mamao o 20 knm. Somewhere ka mau o ka hola ma hope o moe ke keakea ole, ka sperm hiki i ka fallopian paipu, a (ina he mea hua) fertilization ia lŘlŘ.

Loko o ka sperm o ke kane kino ua kokoke,ʻaʻole e neʻe, ka mea, i oleʻeleu a passively hoʻoneʻe ma ka spermatic ducts, pu me seminal loli ma muli o ke peristaltic ka neʻe 'ana o ka cilia a me ducts.

Ke ola kīkoʻo o ka sperm

Epekema a me na physiologists i ho'āʻo i ka hana me ka ninau o kahi sperm e hana a ke kumu ka mea, i hōʻano kekahi manawa? Ua huli mai i ka mea a pau kaʻina hana o ka maturation o gametes lawe oi aku mamua o na malama elua, akā, kiʻi ka mea, he nui helu. E like me ka hopena, na kanaka i ole shortage o aaiaoe mea.

Ke viability o ka sperm ua hoopaa wale no o ka malama, i ko lākou pono i nā kūlana akau:
- ka mahana ma luna o 32 kekelē Kelekia ma;
- i ka wa e kaawale aku o hoʻoʻino ka maʻi.

Akā, mawaho o ke kāne kino, na keena hoopaa lākou ka hoʻoneʻe no i hiki i kekahi lā. Loko o ka uterus, i kēia manawa e e hoopomaikai io ia i na la ekolu.

He aha ka spermatogenesis?

Spermatogenesis - o ke kahua o ka sperm, a ia lŘlŘ ma lalo o ka makaʻala rula o ke kino o ka endocrine nenoaiu.

Ua pau hoʻomaka me ka hiki keena, a ma hope o kekahi mau māhele lawe i ke kino o kekahi kanaka makua sperm. Ke kaumaha ma muli o ka laha 'o sperm maturation kaʻina e ĸokoĸa ana nä pane. No ka laʻana, ma chordates i ka embryonic wā waiho kūikawā aeee e neʻe i ai i na gonads a me primordia ke ano loko o ke keena, a a laila lilo spermatozoa.

Spermatogenesis i kanaka

Ka papa hana no ka ho okumu i ka sperm ke kanaka, aole ia i oko mai ia o nā vertebrates. Ke kaʻina hoʻomaka i puberty (makahiki 12) a kŰlń kokoke mai i ka 80 makahiki.

E like me ia i kekahi kumu, sperm maturation kalapona mau 64 lā, ma luna o ka mea 'ē aʻe - i 75 mau lā. Akā, me ka loli o ke omo epithelium (a mea he kūpapakū no ka mea reproductive aeee) mea ole e emi malalo o hookahi i loko o 16 mau lā.

Ka holoʻokoʻa kaʻina paa wahi i loko o ka convoluted seminiferous tubules o ka testis. Ma ka hale ilaloʻili lahilahi o tubules hoonohonoho spermatogonia a me spermatocytes o ka mua a me ka lua o ka papa, a laila differentiate i loko oʻo halepaahao. First a hiki aeee e hele ma kekahi mau pōʻaiapuni o ka mitosis mahele, a me ia mea e lawa, OIeEOEIeAeEIIe, i ka meiosis. E like me ka hopena o keia mahele hope produces mau kaikamahine spermatocytes, a laila, i kekahi mau spermatids. Kēlā me kēia no kēia mau keena i ka hapalua o ka helu ana o chromosomes a hiki fertilize ia i hua manu.
