Ama glans wepipi

I-anatomy yesilisa ekhombisa indawo ye-glans penis

I- glans penis, ejwayele ukubizwa ngokuthi i- glans, iyisakhiwo esisekugcineni kwepenisi ezilwaneni ezincelisayo zesilisa.Kuyisakhiwo esibucayi esibucayi ekugcineni kwendoda yomuntu, futhi sinobungqingili ngokwasendalweni yesikhumba sowesifazane womuntu.Umthondo we-glans ungaba bushelelezi, ucwebezele, uvuleke, noma uhlukaniswe kwezinye izilwane ezincelisayo.

Imvamisa, i-glans imbozwa ngokuphelele noma ngokwengxenye ijwabu elisebantwini, ngaphandle kwalabo abasokile.Ijwabu ngokuvamile lingahlehliswa ngaphezulu futhi lidlule i-glans, futhi lingahle lihlehle ngokuzenzakalela ngesikhathi sokwakhiwa.I-glans yaziwa kakhulu ngokuthi "ikhanda" noma "ithiphu" yesitho sangasese.Igama lezokwelapha lisuselwa kumagama esiLatini athi glans ("acorn") nepenis ("of the penis").

Isakhiwo[hlela | Hlela umthombo]

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[hlela | Hlela umthombo]

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[hlela | Hlela umthombo]

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]
