Testicle - ndichiyani? Kapangidwe ndi ntchito ya testes wamwamuna

Machende zambiri amatchedwa testes wamwamuna - mbali amazipanga zofunika kwa thupi mwamuna ndi ziwalo zoberekera makamaka.

Mu masiku akale, pamene munthu analumbira kuti adzakhala kunena zoona, nakhudza machende wake. Ngati munthu ali ndi machende onse, anali chizindikiro chachikulu cha umuna wake. Anthu ambiri amadabwa kuti: "machende - ndichiyani?". Tiyeni tione m'nkhani ino.

Machende nthawi olekanitsidwa mzake ndi imakonzedwa mu M'mimbamo wa scrotum lapansi. Aliyense wa iwo mwapadera TACHIMATA. Akuimira nyumba yeniyeni ndi ducts seminal. Mu pali spermatogenesis ndondomeko. maselo umuna amene okhwima, kusamukira epididymis, ndiyeno kukamutaya mu ndondomeko ya umuna.

chidwi Ndipotu

Ena asymmetry wa maliseche kwa amuna ndi muyezo chodabwitsa. Ndiko kuti, ziri bwino, palibe nkhawa. Iwo mu zosatheka ali mwamtheradi zopanda phindu pa chonde wamwamuna. Asayansi akukhulupirira kuti asymmetry izi zikhoza kukhala anachita kumbuyo, amene angathe kuchepetsa chiopsezo kuvulazidwa nthawi yomweyo machende onse. Ngakhale oimira ambiri theka amphamvu a anthu ankada nkhawa kuti zonse zimene bwino anakonza ndi chirichonse bwino ntchito.

amuna zambiri kukumana, amene akudutsa chifukwa chakuti testicle munthu angakhale lalikulu kuposa ena. Koma nkhani ngati imeneyi zosafunika. kukula mipira osiyana - chodabwitsa wamba. kulemera zingasiyane magalamu 25 mpaka 50.

Choncho testicle - ndichiyani? Kodi ndi zovuta lili pa ndondomeko ya spermatogenesis amuna chiyani? Pa lino.

Machende ndi gonads wamwamuna yotulutsa testosterone ndi umuna.

Kutentha zomwe ndi mulingo woyenera ndi zofunika spermatogenesis ndondomeko dongosolo anapereka mwa mwamuna scrotum testicle. Kuvala zovala pafupi kwambiri ndi zolimba, komanso nkhanza za zothandiza kuti mu malo osambira ndi saunas zingachititse osabereka. Komanso, zoyambitsidwa ano, monga mkangano mipando galimoto zingakhudze thanzi anthu. Choncho chitonthozo ndi bwino kumwa izo.

Mu akafufuza ntchito yovuta wa testes mwamuna akhoza kusonkhanitsa mfundo zothandiza zokhudza mankhwalawa osabereka. Tikaona zikuchokera dontho la umuna, mungamvetse zimayambitsa osiyana kukhala osabereka anthu. matenda yake, nayenso, limachititsa njira yoyenera kuchipatalako.

Kapangidwe, kukula ndi thunthu

machende anthu imakonzedwa kovuta. Ichi ndi chifukwa ntchito zawo zofunika. Iwo zimatulutsa m'munsi, chapamwamba, kumbuyo kumapeto ndi mbali pakati. Ku gawo kumbuyo adjoins ndi epididymis.

The machende ndi wophatikizidwa ziwalo, ndi pang'ono flattened chowulungika mawonekedwe. Asanabwere zonse wamwamuna msinkhu, epididymis maliseche kukhala pang'onopang'ono, koma ndiye kukula inapita patsogolo kwambiri.

TACHIMATA, amene achoka ku kugawa. Iwo anagawana thupi mu zigawo - uliwonse uli 270 zidutswa.

Kapangidwe ndi ntchito ya maliseche ndi

• Mu lirilonse la lobes 270 ndi kwa wina mbeu zitatu njira Njoka mawonekedwe ndi kutalika 75 masentimita (mwa iwo akupezeka spermatogenesis ndondomeko). Choncho utali wonse wa tubular ndi angathe kukwaniritsa pafupifupi 500 meters. mawonekedwe njira ndi kudzatha mu mediastinum, ndi mitsinje kukhala rete testis, limene lili mu plexus testicular.

• plexus wa njira ndi njira 15 efferent iwo kulowa epididymis (epididymis), kupanga potero mutu. Luso la umuna umuna limapezeka pokhapokha iwo kudutsa epididymis lapansi.

• njira Kumvetsela bwino ikuyenda mu ritsa umene umabweretsa mbewu. Vas deferens imodzi akuimira mbali ya chingwe mbewu. The otaya amapita ku chikhodzodzo kupyolera lonse ducts inguinal. Ndi m'dera la chikhodzodzo, vas onse deferens converge ngati kuli kotheka.

• vas deferens (a testis mwamuna) pa mapeto a yaitali pang'ono kuti imagwiritsidwa ritsa ejaculatory. m'litali ndi za ziwiri masentimita. Iye mitanda prostate nakatsegula ndi kutsegula yopapatiza pa chitunda njira anafuna kupanga mkodzo.

Tsopano ine ndikumvera izo ndi zimene - ndi testicle. Iwo ali wabwino magazi okwanira, choncho zimatheka kuuzana chokwanira cha metabolites timadzi. komanso amalola kusintha kutentha. Kutentha kwa testes mu amuna pang'ono pansipa kutentha yachibadwa thupi zokha ndi digiri theka. A kutentha khungu padziko scrotum ngakhale m'munsi - kwa madigiri zitatu ndi theka m'munsi.

Kudzera zotsatirazi zifukwa ziwiri akhoza anakhalabe otsika kutentha scrotum mwamuna ndi testes kuti ali momwemo:

1. Khungu la scrotum ndi woonda kwambiri.

2. Specific choroid plexus, mmene mtsempha wamagazi inali pakati pa magawo testicular, kuli kuluka mitsempha.

Kapangidwe ka mwamuna testis pa mlingo ma

14% buku okwana kulamulidwa ndi interstitial minofu mafuta. Iye, nayenso tichipeza mlongoti kugwirizana selo, maselo Leydig, capillaries, connective minofu macrophages zidutswa.

70% wa testes okwana wamwamuna zatenga njira seminal zomwe zigwirizana mitundu itatu ya maselo somatic: peritubular, maselo Sertoli, maselo nyongolosi.

Albuginea. Dzira spliced ndi izo. Ndi ili mu mapepala choipidwa ndi parietal. Pamodzi iwo apanga chipolopolo kugwirizana ndi mitolo ya minofu chikhalidwe. matabwa izi kusunga machende bwino, kusonyeza kupewa zodabwitsa.

Albuginea ili pafupi testikulnogo m'mphepete kumbuyo ndipo dongosolo yeniyeni unakhuthala. Ndi thickening izi achoke partitions kupanga minofu connective. Iwo amagawira ena ambiri magawo dzira.

The mulingo wa maliseche a

Machende munthu wamba sayenera zosakwana kukhetsa.

The mulingo ndi masentimita anayi m'litali ndi masentimita atatu m'lifupi.

Pali zinthu zimene amuna nkhawa kukula ndi malo machende awo. Ngati amasiyana mzake ayi centimeter kuposa wina, ndipo palibe ululu, ndiye palibe kalipokalipo. Koma ngati kupatuka ndi centimeter lalikulu kuposa wina, ndi bwino nthawi yomweyo kukaonana ndi katswiri.

Kodi zimakhudza kukula kwa chiwalo wophatikizidwa?

Pali maganizo ntchitoyo machende chimadalira pa kukula kwawo. Chifukwa china choona. Mwachitsanzo, taganizirani chimpanzi. Kukula kwa maliseche awo woposa wa anyani ndi anyani zambiri kugonana zambiri kugonana khalidwe kuposa anyani. Komabe, kafukufuku bwinobwino munda, asayansi osati anachita. Si chinsinsi kuti anthu akuda ndi machende kuti ndi kawiri kukula kwa maliseche a amwenye wamwamuna. Koma ngati mukuziyenereza luso manyowa Asia ndi akuda, zimaonekeratu kuti umuna sikudalira kukula kwa maliseche amuna.

Ntchito yaikulu ya maliseche a

Ntchito yaikulu ya maliseche kupanga ndondomeko ndi olemekezeka mahomoni mwamuna kugonana ndi zina yogwira komanso endocrine ndi ntchito zobereka. maphunziro timadzi testosterone ndi tanthauzo lenileni la endocrine ntchito. magazi thupi antabira ndi ku testes lapansi.

Iwo akachite zinthu ntchito zofunika kwambiri pa secretory limba - kotunga magazi mahomoni otukuka. Komanso ali ndi ntchito ya katulutsidwe mkati - manufactures ndi maselo nyongolosi.

Kodi umakhudza mlingo testosterone mu thupi?

• Mothandizidwa testosterone pa thupi akufotokozera mtundu yachibadwa wamwamuna: kapangidwe wapadera wa m'mphako ya timinofu kuonjezera makulidwe a amuna, khungu.

• kukula ndi chitukuko kabwino ka zokhudzana ndi prostate, aamuna seminal vesicles.

• Kukula kwa minofu thupi.

• Mapangidwe ndi libido wamwamuna.

• kukula ndi chitukuko kabwino ka maliseche kunja.

Takambirana mwatsatanetsatane testicle. Kodi panopa amadziwika.
