Isende - kuyini? Isakhiwo nemisebenzi testes besilisa

Amasende ngokuvamile okuthiwa testes wesilisa - indima emangalisayo ebalulekile emzimbeni besilisa uhlelo zokuzala ngokukhethekile.

Ezinsukwini ubudala, lapho indoda wafunga wagomela ethi uzokutshela iqiniso, wamthinta amasende abo. Uma indoda bobabili amasende, kwaba uphawu enkulu ngobudoda bakhe. Abantu abaningi bayazibuza: 'amasende - kuyini? ". Ake sihlole kulesi sihloko.

Amasende njalo behlukene futhi ahlelwe ngalo ingaphakathi of the scrotum. Ngamunye babo camera ngokukhethekile. Zimelela izinhlaka eziqondene kokuba Amapayipi kwesidoda. Them nanso is inqubo spermatogenesis. Isidoda amaseli oye wabonisa ukuvuthwa kuso, ezihambayo phakathi epididymis, bese ziyalahlwa e inqubo ejaculation.

Eqinisweni ezithakazelisayo

Ezinye asymmetry we amasende ezingabantu ngumkhuba ojwayelekile. Lokho, kulungile, akukho okufanele ukhathazeke ngakho. It neze has nhlobo nomthelela wenzalo besilisa. Ososayensi bakholelwa ukuthi leli asymmetry kungaba yokusabela ukuzivikela, okuyinto kunganciphisa ingozi yokulimala ngesikhathi esifanayo bobabili amasende. Nakuba abameleli abaningi nengxenye enamandla abantu babekhathazeke ngokuthi bonke baye lahlela kahle futhi yonke into nokusebenza ngendlela efanele.

amadoda ngokuvamile ukuhlangabezana, ababhekana ngenxa yokuthi omunye isende kungenzeka ibe inkulu kunenye. Kodwa lezo zinto akudingekile. Ezahlukene usayizi amabhola - Kuyaziwa. Isisindo sawo zingahluka kusuka 25 kuya 50 amagremu.

Ngakho isende - kuyini? Uyini umthelela elinako inqubo spermatogenesis ezingabantu? On lokhu kamuva.

Amasende kukhona gonads besilisa ukuthi ukukhiqiza testosterone kanye nesidoda.

Amazinga okuyinto elilungile kanye ezidingekile inqubo spermatogenesis ilungiselelo enikeziwe in owesilisa scrotum isende. Egqoke izingubo basondelene kakhulu futhi unganyakazi, kanye nokuhlukunyezwa imikhankaso kule obhavu kanye sauna kungabangela inkinga yokungabi nenzalo. Ngaphezu kwalokho, yizinto zesimanje, ezifana izihlalo ezifudumalayo imoto kungathinta kwezempilo zamadoda. Ngakho induduzo kungcono hhayi kabi.

Ngo ucwaningo imisebenzi abagxeka testes besilisa bangahlangana ukwaziswa okuwusizo ezihlobene ekwelapheni ukungabi nenzalo. Uma sihlaziya ukubunjwa isidoda, ungakwazi ukuthola izimbangela ezahlukahlukene ukungazali ezingabantu. Imiphumela yaloku kuhlola okungenhla Esifike Ngesikhathi yena, wenza sikwazi ukuthatha izinyathelo ezifanele ukwelashwa.

Isakhiwo, ubungako kanye nokwakheka

amasende zabesilisa ahlelwe nzima impela. Lokhu kungenxa ayekuthunyiwe ezibalulekile. Zikhiphela ephansi, engenhla, ekupheleni akha ingxenye yazo ephakathi nendawo. Ukuze ingxenye esemuva adjoins le epididymis.

Emasendeni zibhangqwe izitho, kokuba esiyisicaba ukuma kancane okusaqanda. Ngaphambi kokuba eze besilisa ukuthomba egcwele, epididymis futhi amasende zikhula kancane kakhulu, kodwa ke ukukhula kwabo yashesha kakhulu.

Camera, okuyinto isuka ukwahlukanisa. Babelana umzimba zibe izingxenye - aqukethe 270 izingcezu.

Sakhiwo umsebenzi emasendeni

• Ngo ngayinye iyizingxenye 270 kuyinto eyodwa kuya imbewu ezintathu isiteshi oyinyoka ukuma kanye nobude 75 amasentimitha (kuzo kwenzeka inqubo spermatogenesis). Ngakho ubude isamba ijabulise uyakwazi ekufezeni cishe 500 metres. umumo siteshi kuyalungiswa ku mediastinum, futhi iziteshi babe testis rete, okuyinto Itholakala plexus wamasende.

• plexus iziteshi iziteshi 15 efferent bengena epididymis (epididymis), ukwakha kanjalo ikhanda. Ikhono kwesidoda kokukhulelwa livela kuphela ngemva kokuba adlule epididymis.

• iziteshi Ongaphansi ngokushelela egeleza imbobo okuletha imbewu. Vas deferens kanyekanye limelela ingxenye intambo imbewu. Ukugeleza iya kwesinye ngokusebenzisa Amapayipi ububanzi inguinal. Kuyinto endaweni kwesinye, kokubili vas deferens bukhomba ngangokunokwenzeka.

• vas deferens (the testis besilisa) ekupheleni a enwetshiwe kancane esakha imbobo ejaculatory. Ubude bayo ababili ngamasentimitha. Yena kweqa wendlala futhi ivula ukuvulwa emincane esiteshini indunduma okuhloswe ukwenziwa umchamo.

Manje ngiyaqonda ukuthi iyini - the isende. It has an kakhulu liningi igazi, futhi ngenxa yalokho abafumene exchange ezanele metabolites futhi hormone. futhi ikuvumela ukuba ulungise lokushisa. I lokushisa testes kwabesilisa kancane ngezansi lokushisa lomzimba evamile kuphela mayelana nengxenye ngezinga elithile. A lokushisa isikhumba ebusweni the scrotum ngisho aphansi - I-degrees ezintathu nengxenye engezansi.

Ngokusebenzisa lokhu okulandelayo ezinqubweni ezimbili abacabanga ukuthi zigcinwe okushisa aphansi scrotum besilisa testes yawo:

1. isikhumba scrotum mncane kakhulu.

2. Specific plexus choroid, lapho umfula elise phakathi tincetu wamasende, emithanjeni ezinabantu aluka.

Isakhiwo besilisa testis emangqamuzaneni

14% of the volume Imininingwane elalihlala interstitial amafutha kwezicubu. Yena, siqukethe insika cell uxhumano, Leydig amaseli, ama-capillary, zezinzwa izicubu macrophage izinsalela.

70% testes besilisa Imininingwane hlala iziteshi kwesidoda okuyinto aqukethe ezintathu zamangqamuzana ukuphathwa kwabathintwayo: peritubular, Sertoli amangqamuzana, amangqamuzana lwegciwane.

Albuginea. Egg spliced nalo. Itholakala amashidi visceral futhi parietal. Bebonke bakha igobolondo elihlobene ne izinyanda kwemisipha nemvelo. Lezi imishayo ugcine ngamasende ngempumelelo, ngaleyo ndlela sivumele ukugwema uthuthumele.

Albuginea etholakala eduze testikulnogo onqenqemeni akha isakhiwo ethile iye uqweqwe. Ngalokhu ukuqina suka ngodonga ukwakha ezicutshini. Bahlanganyela inani elikhulu amaqanda tincetu.

Usayizi esezingeni emasendeni

Amasende umuntu osesilinganisweni akufanele kube ngaphansi kuka-abakhwabanisi.

Usayizi ovamile ngamasentimitha amane ubude futhi ngamasentimitha amathathu ububanzi.

Kunezimo ukuthi amadoda bakhathazeke ngobukhulu nendawo amasende abo. Uma ihluke nomunye ningasoze isentimitha angaphezu kwelilodwa, futhi akuyona ubuhlungu, i-ukuthi asikho isizathu sokukhathazeka. Kodwa uma ukuphambuka mkhulu kwelilodwa isentimitha, kungcono ngokushesha uthintane onguchwepheshe.

Yini kuthinta ubukhulu isitho abhanqiwe?

Kukhona umbono ukusebenza emasendeni incike ubukhulu babo. Ngokwengxenye lokhu kuyiqiniso. Njengoba isibonelo, cabanga yenkawu. Usayizi amasende obukhulu kunobukaJohane gorilla kanye nezimfene abe okuningi sexual uhlamvu kuka-gorilla. Nokho, ucwaningo eqondile kulo mkhakha, ososayensi ungazange lwenziwa. Akusiyo imfihlo ukuthi abantu abamnyama babe amasende ukuthi kukhona enkulu ngokuphindwe kabili kunezwe emasendeni ka Asians besilisa. Kodwa uma uqhathanisa ikhono zalisa Asians kanye abamnyama, kuba sobala ukuthi kokukhulelwa akuxhomekile usayizi emasendeni ezingabantu.

Umsebenzi oyinhloko emasendeni

Umsebenzi oyinhloko inqubo amasende ekwenziweni yisona sakhiwo esibhekele hormone wesilisa ocansini kanye nezinye izinto asebenzayo kanye endocrine kanye umsebenzi okuzala. imfundo i-hormone testosterone kuyinto Mayelana nencazelo eyisisekelo yegama endocrine umsebenzi. igazi zomzimba akutholayo kuvela testes.

Zifeza umsebenzi ebalulekile secretory isitho - liningi igazi e-hormone athuthukile. Ngaphezu kwalokho, banalo umsebenzi uketshezi yangaphakathi - silwenza germ cells.

Yini ethonya ezingeni testosterone emzimbeni?

• Ngaphansi kwethonya testosterone emzimbeni eba uhlobo evamile besilisa: isakhiwo olukhethekile amalaka, yephimbo ukwandisa ukushuba yamadoda, ekhanda.

• I ukukhula nokuthuthuka ngendlela efanele ezihlobene futhi wendlala, iduna vesicles kwesidoda.

• Ukuthuthukiswa imisipha yomzimba.

• Ukwakhiwa kwe-libido besilisa.

• I ukukhula nokuthuthuka kahle Izitho zangasese zangaphandle.

Sixoxe ngokuningiliziwe isende. Yini-ke manje seyaziwa.
