Kuti tinzwisise marongerwo uye kwakabva chityu anatomi rubatsiro. Mammary shwanu - a dzakachinjwa apocrine ziya mumasero yakatanga kubva ectoderm. Muvanhu, kukura mammary mumasero ndepana wechitanhatu vhiki intrauterine upenyu. In chityu ganda chitete uye haana simba, rine bvudzi follicles, ziya uye sebaceous mumasero. The mammary shwanu ane muzvizhinji tsinga fibers papfudzi uye remuromo plexus uye intercostal tsinga. shwanu muviri ane convex discoid chimiro, ruvara vaaleanpunainen kazhinji rakachenuruka, nemvumi magadzirirwo, avhareji dhayamita zvitsigiro ndiyo 10-13 masendimita Chipfuva vasikana vane paavhareji kurema 150-200 d uye lactation -. 400-900, pasi Y vakadzi vakawanda vechiduku utano zvinoumbwa shwanu hemisphere uye ndiye uprugimi.Stroenie saizi zamu, chimiro uye nzvimbo vane maitiro uye zvinhu.

The nemamiriro chipfuva chacho anatomi

Mazamu Women vanosvikirwa anoumbwa masero akawanda kuti pave mukaka, izvo inounganidzwa mune lobules. Kubva mumwe nomumwe zvidimbu anoendazve samafuta karwizi, uye vose zvikamu ikashandiswa kupinda zvikamu ane chirwere mutsinga dzinofamba nemukaka umo ikashandiswa zvose chinouraya diki ducts.

Chikamu radially aronga hama kuti munyatso uye takaparadzaniswa umwe adipose tishu. Mumwe mugove shwanu iri yakaita mumwe cône pamwe chakaderedzwa mutengo panguva munyatso, apo anovhura excretory mutsinga dzinofamba nemukaka. Ducts kuti munyatso kuwedzera, pova samafuta sinuses. Akaumba nzvimbo yakapoteredza munyatso inonzi areola, uye duku chikomo pairi - ndizvo ziya mumasero. Sechivako chityu vakadzi hwakasiyana makono shwanu mamiriro.

Kukura mammary mumasero rinoitwa inobvuma prolactin (hormone pamusoro Anterior pituitary) uye ovary mahormone. Nokuda prolactin lactation kunoitika. In yokutanga yezana pamuviri zamu inowedzera kukura, sezvo kumbowanikwa yechipiri yezana kukura epithelial secretory basa partite masero acho ane Formação de. Panoperera nepamuviri uye kwemazuva mashomanana pashure pokuberekwa kunowedzera secretion uye inobereka yellowish, nemvumi zvinovaka zvokunwa inonzi colostrum. Zvadaro kuchinja Kuronga secretions, zvinova zvikuru mvura kusachinja-chinja uye secrete mukaka. Pakazopera zvokudya nguva, kugadzirwa mukaka zvinoderedza uye kudzivirira kusvikira rinotevera pamuviri.

Zamu kukura mune vasikana kunoitika pakuyaruka pakati makore 10-15. The kwacho rinotanga kukura munyatso uye areola peripapillary anotanga zamu kukura vakawanda. Zamu vakadzi iri kukura kwenguva refu uye pakupedzisira yakasimbiswa saizi zamu chete pashure zvokudya mwana. The Penultimate pavaipfuura kukura chityu zvasvika makore 15-17.

Mammary shwanu - labile nhengo, uyewo dumbu iri sei cyclical okunatsiridza. kutanga varikutsika asati kunoitika kuwanda kwemasero, nyama kuzvimba, simbi anova edematous uye friable. Yapera kumwedzi, zviratidzo izvi apere. Maererano nezera nguva nechityu rakakamurwa 4 marudzi.

1. Iron musikana kana mukadzi 20-25 makore. The mammary shwanu ane yunifomu chimiro, mukaka ducts imperceptible premammarnogo nzvimbo makubhiti 5 mm.
2. Kenza vakadzi pakati pemakore 25 uye 40 ndivo vakuru kushingaira. ndima dzaro samafuta vari mudungwe pamwe epithelium, kuramba kukura pamadziro pane mapazi pamwe inouraya secretory vesicles. Sechivako omumuviri zvinosiyana nokuda cyclical kuchinja.
3. Mammary shwanu kubereka. In premenopausal glandular zvinyama iri akaparadza muchimiro zviwi duku iri glandular Triangle, izvo vanoparadzaniswa musango tishu adipose. With zera, uwandu glandular parenhim zvinoderedza yemazamu meshed. Fibrous tishu atrophies.
4. Mammary shwanu postmenopausal vakadzi. In kuenda kumwedzi kuchinja chityu kunova kusingarapiki glandular zvinyama nokupera zvachose, izvozvo displaces mafuta tishu.

Sezvataurwa pamusoro apa, sechivako chityu kunoenderana zera, pamwero kukura sikarudzi, kubva danho kumwedzi pakati pavakadzi, hormone chinzvimbo, ya nepamuviri uye lactation. Age Nde chinhu chinoratidza maumbirwo mhando mumasero. Asi, zvakadaro, pane munhu kusiyana mune rutapudzo uye pave glandular okunze, izvo takatsunga ne alimentary, kwemakemikari anobudiswa uye zvimwe zvinhu.
