Amasende yiwo i-gondolas (i-genital gland) wesilisa. Atholakala ngezansi futhi nhlangothi zombili zomthondo. Abanjwa endaweni yawo yisaka eligoqayo elimise okwesikhumba nezinye izingqimba ezimbalwa ukuze lisivikele. Izicubu zemisipha Ingenye yezendlalelo ezizokwenza isikhwama esakhiwe sishwabane, sishiye amasende ekhululekile kakhulu noma eqoqwe.
Lezi zindlala bangabakhiqizi besidoda kanye namahomoni ocansi kuhlanganise ne testosterone. Ngaphandle kokungabaza sikhuluma ngezitho zezindlala ezinkulu kakhulu ngokulingana nalokho okuyisimiso sokuzala sabesilisa.
Anjani amasende?
Lezi zitho abe nokuma okusaqanda enosayizi ophakathi kwamasentimitha amane kuya kwayisishiyagalombili ubude namasentimitha amabili noma amathathu ububanzi. Bazungezwe isikhwama sesikhumba esibizwa ngokuthi i-scrotumImaholoholo futhi iyanwebeka impela, okuzokwenza izinga lokushisa layo lihlale liphansi kunomzimba wonke, phakathi kuka-1 kuya ku-3 ° ngaphansi. Ukubukeka kwayo, ubunwele noma umbala wayo kuzoncika kakhulu ukusuka kowesilisa kuya kwenye uma kubhekwa uhlanga noma ubudala bayo.
Umuntu, njengakwezinye izilwane ezincelisayo, zinamasende azo lokho zivela engxenyeni yesisu, ngakwesokudla nakwesobunxele somgogodla we-lumbar futhi eduze nezinso. Ekukhulelweni kukamama, umntwana wesilisa ukhulisa amasende endaweni yesisu, kodwa ashiya lesi sifunda ukuze ehlele endaweni ye-groin, ehudula ngayo izikhwama eziwuzungezile futhi ehlanganisa isimo sokugcina.
Amasende anombala obomvu noma oluhlaza okwesibhakabhaka-mhlophe, konke kuzoya ngokuthi uligeza kanjani igazi lakho. Kuvamile ukuthola ama-cysts amancane anamafutha ngesikhathi sokukhula hhayi ebuntwaneni, ama-angiomas abukeka njengezifiso, i-varicose veins, nakuba bonke ngaphandle kokubika noma yiluphi uhlobo lwenkinga enkulu.
Isifunda se-Scrotal
Yiyo yonke indawo evala noma ezungeze amasende, Zimise okwesaka futhi zinde. Itholakala ngaphansi kwendawo ye-pubic, ngaphambi kwe-perineum nangemuva kwepipi. Sonke lesi sifunda sihlukaniswe izingqimba eziningana:
- Isikhumba noma i-scrotum: yinxenye enhle kunazo zonke nengaphandle, lapho kukhula khona izinwele.
- I-Dartos: Kuwungqimba oluqhubeka ku-scrotum, futhi luncane futhi lwakhiwe imicu yemisipha ebushelelezi.
- I-Seros tunic noma i-fascia ka-Cooper: Ine-anatomy efana ne-fibers evela emsipha omkhulu we-oblique wesisu. Le micu ihudulwa ngamasende ukuze yehle isuka esiswini ibheke endaweni escrotal.
- I-Tunic ye-Muscular: Yakhiwe ngokwandiswa kwemisipha ye-cremaster, ehambisana nentambo yesidoda. Imicu yayo iphuma emisipheni yemisipha ebanzi yesisu nayo ehudulela phansi ekwehleni kwesende.
- I-Fibrous Tunic: Imise okwesaka futhi izungeza indawo yentambo yesidoda kanye nesende.
- Ingubo yangasese: ulwelwesi lwe-serous olugoqa ku-testicle kanye ne-epididymis
Isithombe sithathwe ku-Wikipedia naku-Google Amasayithi. Amasende, i-epididymis kanye ne-spermatic funiculus yekati elifuywayo: 1. Ingxenye engaphambili, 2. Ingxenye engemuva, 3. Unqenqema lwe-epididymis, 4. Unqenqema olungaphandle, 5. I-testicular mesentery, 6 Epididymis, 7. Inethiwekhi yemithambo nemithambo isende, 8. Vas deferens.
Umthethosisekelo wesende ngaphakathi
I-testicle kanye ne-epididymis zakhiwe izingxenye ezimbili ezihluke kakhulu. Ingxenye eyodwa iyisembozo esine-fibrous noma i-albuginous esibizwa 'testicular albuginea' futhi yiyo evala isende. Futhi kukhona 'epididymal albuginea' ukumboza i-epididymis.
I-albuginea yamasende Kuyingxenye ene-fibrous kakhulu ezungeze isende, ingxenye yayo yangaphandle yakhiwe 'i-visceral leaflet' yengubo yangasese. Futhi ingxenye yayo engaphakathi ihambisana nezicubu zesende ngokwalo.
Engxenyeni yomngcele ongemuva ophakeme 'Umzimba we-Highmore' lapho kwakheka khona inethiwekhi yamapayipi esidoda ebizwa ngokuthi 'inethiwekhi ye-Haller's. Uchungechunge lwama-lamellae noma i-septum lusuka kwenye yezingxenye ze-Highmore ezinwebekayo ziye ngasemngceleni wesende, lizihlukanise zibe ama-lobule.
Imisebenzi yamasende
Umsebenzi wesende ngokuyinhloko ukuthi dala futhi ugcine isidoda, Kodwa ake sibhekisise ukuthi yini enye engadala:
- Ukukhiqizwa kwesidoda: kwakhiwa amashubhu eseminiferous, engxenyeni engaphandle yodonga lwamashubhu, lapho amaseli amagciwane. Lawa maseli aba yindilinga yokuqala bese eba made, ekugcineni abe isidoda esivuthiwe. Ukusuka lapha bazohamba ngama-tubules ukuze babhukude baye ngase-epidymis, i-vas deferens kanye nama-seminal vesicles, lapho ekugcineni bezogcinwa khona.
- Ukukhiqizwa kwe-testosterone: Itholakala kuzicubu ze-interstitial ukuthi ngesikhathi esifanayo zigcinwe phakathi kwama-tubules, indawo ecebile kumaseli e-Leydig anesibopho sokudala. testosterone. Le hormone izosatshalaliswa emzimbeni wonke ngegazi ukuze ikwazi ukwenza imisebenzi yayo. Uma i-testosterone yehla ngengozi, kungase kube ngenxa yokuthi amasende mancane kakhulu kusukela ekuzalweni (i-testicular atrophy), noma ngenxa yokuthi izicubu zamasende zilahlekile, noma ngenxa yokungena kokunqamuka kokuya esikhathini kwabesilisa noma ukusetshenziswa kabi kwama-anabolic steroids. .
