Inkanda

Umfanekiso wenkanda engenalo ijwabu

Inkanda iyisakhiwo esiyisigaxa esisehlokweni somthondo womuntu futhi esiyindawo yowesilisa evukwa inkanuko kakhulu newumthombo womhlakahlo wenkanuko yezocansi. Inkanda eyingxenye yezitho zokuzala zowesilisa noma iduna ezilwaneni ezincelisayo, futhi ivame ukuba nommomo obushelelezi, omude. Ngaphandle yembozwe ulwelwesi lodenda (mucosal tissue) oluyenza ibonakale ibushelelezi futhi incwabile. Kubantu Inkanda itholakala ngaphezu kwamashodozana (corpora cavernosa) futhi iyingxenye yentefe (corpus spongiosum) yomthondo. Esihlokweni kukhona imbobo yokuchama bese ezansi kukhona idlala elizungezayo (corona glandis). Isicubu esinwebekayo esibizwa umkhala (frenulum), siyingxenye yesiqu sawo. Kubantu esilisa abangasokile, umbozwe gokuphelele noma ingxenye yisikhumba esibizwa ijwabu. Kubantu besilisa abakhulile, ijwabu livame ukubuya liveze inkanda, ikakhulu lapho bevukelwe noma umthondo umile. Inkanda yaziwa kakhulu ngokuthi "ikhingqi" noma "umnqundu".

Umhlakahlo wowesilisa okhombisa indawo yenkanda

Umthondo we-glans yisigaxa esandisiwe se- corpus spongiosum.Ibunjwe emaphethelweni oyindilinga we- corpora cavernosa penis, enabela kude phezulu ngaphezulu kunaphezulu kwayo.Engqungqutheleni yama-glans kune-orifice yangaphandle eqondile ebheke phezulu.Umjikelezo wesisekelo se-glans wakha umngcele oyindilinga wokuphrojusa, i- corona glandis, emboze i- sulcus ejulile ye-retroglandular (i- coronal sulcus ), ngemuva kwayo okuyintamo yomthondo.Ubukhulu obulinganayo bepenisi ye-glans bungahluka kakhulu.Kwamanye amapipi kubanzi kakhulu ukuzungeza kune-shaft, okunikeza ipipi ukubukeka okufana nekhowe, kokunye kuncane futhi kufana kakhulu nophenyo lwesimo.Ubucwebecwebe obuthambile be-glans buthatha umthelela ngesikhathi esinzima sokubambisana. [1]

Ijwabu ligcina i-mucosa endaweni enomswakama. [2] Imithondo esokiwe ine-glans evezwe unomphela futhi yomile.Ucwaningo oluningi luye lwaphakamisa ukuthi i-glans ibucayi ngokulinganayo kuzo zombili izitho ezisokile nezingasokile, [3][4] ngenkathi abanye bebike ukuthi iyazwela kubantu abangasokile. [5] [6]

IHalata & Munger (1986) ibika ukuthi ukuminyana kwezitho zangasese kukhulu kakhulu e-corona glandis, [7] kuyilapho umbiko kaYang & Bradley (1998) "ungakhombisanga zindawo ezisezintanjeni ezingahlehliswa kakhulu kunezinye." [8]

IHalata & Spathe (1997) ibike; "lo glans umthondo iqukethe predominance mahhala kwalapho, eziningi zangasese ekupheleni ama futhi akuvamile Pacinian futhi Ruffinian corpuscles. Ukuphela kwemizwa kaMerkel nezidumbu zikaMeissner azikho. "

U-Yang noBradley baphikisana; "iphethini ehlukile yokugcinwa kwama-glans igcizelela indima ye-glans njengesakhiwo sezinzwa". [8]Abanye abacwaningi baphakamise ukuthi i-glans iguqukele ekubeni yi-acorn, amakhowe noma isigaxa esakhiwe ukuze kuthi ngesikhathi sokukopisha sisebenze ukususa noma yisiphi isidoda esisekhona kubalingani bobulili bangaphambilini, kepha lokhu akusekelwa lapho kubhekwa izihlobo ze-primate ezinokuziphatha okuhlukile kokukhwelana. [9]

Ukubaluleka komtholampilo

I- meatus (ukuvulwa) kwe- urethra itholakala ekugcineni kwepenisi ye-glans.

I- epithelium ye-glans penis iyizicubu ezinomucu.UBirley et al. bika ukuthi ukuwasha ngokweqile ngensipho kungomisa ulwelwesi lwamafinyila olumboza i-glans penis futhi kubangele i- dermatitis engacacisiwe.

Ukuvuvukala kwe-glans penis kwaziwa njenge- balanitis, futhi, kwenzeka ngo-3-11% wabesilisa (kuze kufike kuma-35% wabesilisa abanesifo sikashukela).U-Edwards ubike ukuthi kuvame kakhulu kwabesilisa abanemikhuba emibi yokuhlanzeka noma abangasokile.kunezimbangela eziningi, kuhlanganise ukucasuka, noma ukutheleleka nge ezihlukahlukene Amagciwane.Ukuhlonza ngokucophelela imbangela ngosizo lomlando wesiguli, ukuhlolwa komzimba, ama-swabs namasiko, kanye ne-biopsy kubalulekile ukuze kutholakale ukwelashwa okufanele.

I-Meatal stenosis iyinkinga esedlulile yokusoka, eyenzeka cishe kumaphesenti ama-2 kuye kwangama-20 wabafana abasokile.

Ezinye izilwane

Ama- felids wesilisa ayakwazi ukuchamela emuva ngokugoba ichopho le-glans penis emuva. [10]Emakati, umthondo we-glans umbozwe imiqolo, kepha ezinjeni, i-glans iyashelela.Penile ameva futhi senziwe glans owesilisa nowesifazane izimpisi nezimanakanaka.

Ezinjaneni zesilisa, i-glans penis iqukethe izingxenye ezimbili ezibizwa nge- bulbus glandis ne- pars longa glandis.Ubukhazikhazi bomthondo wefossa buya cishe maphakathi nomshayo futhi bunamaphiko ngaphandle kwethiphu. Ngokuqhathanisa, ubukhazikhazi bezinwele ezimfishane bufushane futhi bucwebezela, kanti obama-viverrids bushelelezi futhi bude.Ukuma kwama-glans kuyahlukahluka phakathi kwezinhlobo ezahlukahlukene ze- marsupial.Kuma-marsupial amaningi, i-glans ihlukene phakathi, kepha ama- macropods wesilisa ane-glans penis ehlukanisiwe.Umthondo we-glans ubuye uhlukaniswe izingxenye ezimbili kuma- platypus nakuma- echidna .

Umthondo we-glans we- marsh rice rat umude futhi uqinile, [11] ulinganiselwa ku-7.3 mm (0.29 in) ubude no-4.6 mm (0.18 ku) kubanzi. [12]

KuThomasomys ucucha umthondo we-glans uyindilinga, mfushane, futhi mncane futhi uhlukaniswe ngokukha phezulu waba uhhafu wesobunxele nangakwesokudla ngomkhombe ongenhla nomqolo phansi.Ingxenye enkulu yama-glans imbozwe ngemigogodla, ngaphandle kwendawo eseduze kwethiphu. [13]

Igundane likaWinkelmann lingahlukaniseka kalula ezihlotsheni zalo eziseduze ngepipi lalo elincane likathayela. [14]

Lapho imile, ubukhazikhazi bomthondo wehhashi bukhuphuka ngamahlandla ama-3 kuye 4 times.I- urethra ivula ngaphakathi kwe- urethral fossa, isikhwama esincane ekugcineni kwe-glans.Ngokungafani nobukhazikhazi bomuntu, ubukhazikhazi bomthondo wehhashi buhlehlela emuva kushafti yalo.

Amalulwane kaRacey's pipistrelle bat anepipi elincane elimise okweqanda. [15]

Umthondo we-glans wepipi wesilisa we- cape ground mkhulu nge- baculum evelele. [16]
