Amabele amabhinqa, awaziwa nangokuthi iimbumba ze-mammary, zikhona phambi komzimba. Bayaphuma eludongeni lwesifuba phakathi kwesisu nangentamo. Ekubeni i-gland iyilungu okanye inxalenye yomzimba onokudala into okanye ukuvalwa, amabele akwazi ukuvelisa ubisi lwebele . Ikhono lokwenza ubisi lwebele luvumela abafazi ukuba banikele ukutya kunye nokutya kubantwana babo ngokuncelisa .
Anatomy
Nangona ubungakanani kunye nesimo samabele kusenokuhluka ngokubanzi ukusuka kumfazi ukuya kumfazi, onke amabele akhiwe ngamalungu afanayo. Nalu uluhlu lwezakhiwo zangaphandle nezangaphakathi ezenza i-anatomy yebele.
Ingaphandle
Isikhumba: Amabele ahlanganiswa ngesikhumba. Ulusu olujikeleze isifuba luqulethe i-areola, ingono, kunye neengqungquthela zaseMontgomery.
I-Areola: I-areola yile setyhula okanye indawo ye-oval kwisibilini sesifuba esingumbala omnyama kunesikhumba esijikelezileyo. Kukholelwa ukuba i-areola ibumnyama ngombala ukuze umntwana osanda kuzalwa angakwazi ukuyifumana ngokulula ukuba angene kunye nokuqalisa ukuncelisa.
Ingxowa: Ingono ikhupha ngaphandle evela kwiziko le-areola. Kukho iminyango emincinci emininzi evumela ukuba ubisi lwebele luqhubeke phakathi kwebele kunye nomlomo womntwana.
I-Montgomery Glands: Kwangaphandle kwenzalo kunye ne-areola ziphakanyisiwe, iimbumba ezincinci.
Ezi zigcawu zivelisa umfihlelo ohlambululayo, ophucula, kunye nokukhusela intonga kunye ne-orola ngexesha lokuncelisa. Kukholelwa ukuba iintlanti zeMongomery , okanye i-asolar glands, zivelisa isiphunga esinceda umntwana osandul 'ukufumana intsontsho.
Ingaphakathi
Iingxube ze-Glandular: Izicubu ezinobungqingili ebileni yintshuzi yokwenza ubisi.
Le nxalenye yebele eveza ubisi lwebele.
Amakhupha omlambo: Amanzi amanzi yindlela yokuthutha ubisi lwebele. Bathwala ubisi ukususela apho lwenziwa khona kwiisisitye ezinobungqingili, ngokusebenzisa isifuba, nangaphandle kwesikhumba kumntwana.
IiLigaments: I-ligaments ye-Cooper iyimigca yamathambo enobumba abanika isifuba ngesakhiwo. Ekubeni kungekho zihlunu eziphakathi kwamabele, iigaments zinika isifuba isimo sayo.
Amagulane: Kukho inkqubo eyinkimbinkimbi yeentsholongwane ezifumaneka kuwo onke amabele. Ezi zinzwa ziphendula kumntwana oncelisayo kunye nokubangela ukukhululwa kwamahomoni i- oxytocin kunye neprolactin . I-Oxytocin kunye neprolactin zinoxanduva lwe -reflex ye-down-down kunye nokuqhubeka kokuvelisa ubisi lwebele.
Izithambo ezinamafutha: Izicubu ze-Adipose, okanye izicubu ezinamafutha, yintoni eyenza ubukhulu bebele. Amanqatha amaninzi angaphakathi kwamabele, aphezulu amakhulu amabele aya kuba. Nangona kunjalo, inani lamanqatha alinanto nantoni na enokuyenza kunye nenani lokwenza ubisi ngaphakathi kwebele. Ngako oko, ubungakanani besifuba asinakuqikelela inani lobisi lwebele olwenziweyo.
