Isakhiwo emasendeni

Emasendeni noma, ngamanye amazwi, lo testes kukhona yangaphakathi ocansini izitho besilisa. Isakhiwo testes has a ezimbili umsebenzi: kumiswa sperm incretion hormone. La ma-hormone ukunikeza amadoda ukubukeka ehlukile wesilisa, enephimbo elibhodlayo, khona izinwele ebusweni. Futhi ukunquma ethize yokuziphatha besilisa sengqondo.

Usayizi osezingeni amasende 3-4,5sm nge isisindo 20-30 amagremu. Ziyakwazi esikhwameni zesikhumba ngokuthi the scrotum. isikhumba Scrotal esikhunjeni ngaphandle ukwahlukanisa phakathi amaqanda embryonic kuyinto umphetho bangahluka kakhulu ngombala kusukela isikhumba scrotal. It has a inombolo enkulu sebaceous nomjuluko nezindlala, ukwabiwa elinendawo iphunga othize.

Kakade ezinyangeni lokuqala testes fetus izinhlamvu ziqala ukwakheka. Basuke etholakala eduze izinso, base ozakwehlela scrotum. Umbuzo, liyini iphuzu kule ukuguqulwa? It kuvela, likhulu kakhulu. Iqiniso lokuthi ukuthuthukiswa kwesidoda edingekayo lokushisa ongaphakeme - endaweni ethile 34 ° C. Njengoba ungacabanga, lokhu lokushisa awutholakali phakathi nomzimba futhi the scrotum asekelwe izimo nje efanelekayo kumiswa spermatozoa. Ngakho, amadoda ohola ukuphila umzimba, kufanele uvuke ngezikhathi ezithile, ukuze emasendeni babe kude umzimba kushisa futhi selehlile.

I testes sizungezwe igobolondo futhi bahlukana ngu ukwahlukanisa. Hung kubo ku intambo spermatic, esakhiwa yena, we vas deferens, imisipha, imizwa, igazi lymph. Imisipha, ebizwa ngokuthi cremaster ngaphansi ekunciphiseni kuqinisa iqanda emzimbeni yaso ekhululekile okuhlukana nomzimba. Wayebonakala ngokuzenzakalela igcina izinga lokushisa ngaphakathi the scrotum. Ezimweni efudumele, ehlatshwa engezansi, bese emakhazeni, kunalokho, kuthiwa some emzimbeni. Futhi, scrotum kuyinto izoni erogenous babantu.

Egg has izakhiwo ukweseka eziningana. Ngokwesibonelo, e-epididymis amasonto amabili abavuthiwe isidoda amaseli, lapho ukuthola ukuhamba ezidingekayo. Isakhiwo testes kanje: ngaphansi Tunica egg shell kuyinto parenchyma. Siqukethe iyizingxenye amaningi (250 kuya ku-300) ukuthi ugcwele tubules seminiferous. Ngo ngayinye Lobe wabo ababili noma abathathu, 70-90 mm ubude, basuke eligoqiwe. Zakhiwa epithelium seminiferous, lapho isidoda kukhiqizwa.

Isakhiwo testes wukuthi ingxenye clove kuyinto ezicutshini ukuthi amahomoni wesilisa - testosterone. It kuvela ukuthi testes zinemisebenzi emibili - yiwona endocrine nezindlala, amahomoni ubhekiswe ngqo igazi, ngesikhathi esifanayo - excretory indlala, okuholela out isidoda ngaphandle. Isakhiwo testes wukuthi isidoda kuphela akhiwa kuzo. Kumiswa ingxenye liquid isidoda is of wendlala uketshezi kanye vesicles kwesidoda. I endlaleni engasesinyeni iseduze peritoneum, esimweni ekuguleni udokotela azizwa ke ngokusebenzisa ingemuva. Uveza uketshezi okuthiwa juice Prostatic. Ngokubukeka - uketshezi nomhlophe kanye iphunga sici, esingekho kuwo wakhiwa cishe ngokuphelele amaprotheni.

vesicles kwesidoda ngaphezu endlaleni engasesinyeni. It abhanqiwe isitho, usayizi waso eseduze - 5h2h1 ukubona Bubbles ukukhiqiza uketshezi aphuzi nge viscosity ephakeme, okuyinto kusiza ukunyakaza kwesidoda ..

Njengoba sekushiwo, epididymal isidoda nokuvuthwa senzeka, lapha zigcinwa. Isakhiwo futhi yakhiwa testis owesilisa tubules seminiferous, okuyinto uhlangane ukwakha tubules efferent mayelana 15 egeleza phakathi epididymis.

Njengoba isidoda akhiqizwa emasendeni, awukwazi ukususa bebodwa, ukunyakaza kwabo kungenxa yokucindezeleka okwandayo esikhathini amasende ngokwabo ngenxa ukwakheka isidoda esisha.

izindlela Ejaculatory Uyi phambili epididymis. Isidoda ukukhuthazwa ejaculatory izindlela ezenziwe amagagasi elihambisana nokuncipha kwemisipha.
