Mazamu edzimai, anozivikanwawo semakumbo emamota, anowanikwa mberi kwemuviri. Dzinobva mudanda rechifuva pakati pemudumbu nemutsipa. Sezvo gland iri nhengo kana chikamu chemuviri chinogona kugadzira chinhu kana kuchengetedza, mazamu anokwanisa kubereka mukaka wemvere . Iko kukwanisa kuita mukaka wehadzi kunobvumira vakadzi kuti vape chikafu nekudya kune vana vavo kuburikidza nekuyamwisa .
Anatomy
Kunyange zvazvo ukuru uye chimiro chemazamu chinogona kusiyanisa zvakanyanya kubva kumukadzi kusvika kumukadzi, mazamu ose anoumbwa nezvikamu zvakafanana. Heino runyorwa rwekunze nekunze kwezvivako zvinoumba mararamiro emukadzikadzi.
Exterior Parts
Ganda: Mazamu akafukidzwa neganda. Ganda rakakomberedza ramazamu rinosangana neArosola, mbiru, uye gland reMontgomery.
Areola: The asola isvirumendi kana nzvimbo yechipfuva iri pakati pezamu iyo iri mutsvuku wakaita seyemukati weganda. Inofungidzirwa kuti ma-asola ari madema mumarara kuitira kuti mwana achangobva kuwana awane nyore kuitora kuti atange kunwisa.
Nipple: Inguru inofamba kunze kubva pakati peasola. Kune zvikamu zvishomanana zvekuzarura mumukono unobvumira mukaka wemvere kuti uyerere kubva muzamu uye mumuromo wemwana.
Gondgomery Glands: Kunze kwemberi uye areola vaduku vanokwidziridzwa, zvipembenene zvakashata.
Izvi zvinokonzera kuchengetedza kunonatsa, kunopisa, uye kunodzivirira mhondi uye isola panguva yekuyamwisa. Inofanirwawo kutendwa kuti maglandzi eMontgomery , kana glandzi, zvinogadzira chinonhuwira chinobatsira mwana achangowana kuwana mutsara uye chigamba.
Interior Parts
Nhengo dzeTisue: Mucherechedzo mutsva muzamu ndeyekuita mukaka.
Ichi ndicho chikamu chemuzamu unobudisa mukaka wemvere.
Mazi Ducts: Mazamu emisi ndiyo inotakura mazamu emukaka. Vanotakura mukaka kubva kwawakaitwa muzvinyorwa zvinoputika, kuburikidza nezamu, uye kunze kwemukoko kusvika kumwana.
Ligamende: Mitsipa yeChrist is mapepa emagetsi anopa mazamu nemapuranga. Sezvo kusina mishonga iri mukati mazamu, magamente anopa mazamu maitiro ayo.
Mitsipa: Pane hutano hwakaoma hwemitsipa inowanikwa mukati mazamu. Iyi mitsipa inopindura kune anoyamwa pazamu uye inotanga kusunungurwa kwemhomoni ye oxytocin uye prolactin . Oxytocin uye prolactin vane mutoro wekuregererwa-pasi uye kufambira mberi kwekuita mukaka wemvere.
Mafuta Matsi: Zvidimbu zveAdipose, kana mafuta, ndiyo inotarisa kuwanda kwezvipfuva. Kana mafuta akawanda ari mukati mazamu, zvakanyanya mazamu achava. Zvisinei, huwandu hwemafuta hahuna chokuita nehuwandu hwomukaka unoita mukaka mukati mezamu. Nokudaro, mazamu ehupfuu haatauri huwandu hwemukaka wamazamu hunoitwa.
