Ka 'ole o ka umauma, kona ulu ana

E maopopo i ka 'ole a me ka kumu o ka umauma'anatomia kōkua. Mammary gland - he Hoʻololi 'apocrine hou glands hoʻomohala mai ka ectoderm. Ma kānaka, i ke kūpono 'ana o ka mammary glands ia lŘlŘ i ka ono o ka hebedoma o intrauterine ola. Ma ka umauma ili mea lahilahi, a maikaʻi ke kino, ka mea, he lauoho follicles, hou a me ka sebaceous glands. Ke mammary gland i ka ai iiiaanoaa o nā aʻalolo olona, mai ka'ūhā mua a me ka cervical plexus a me intercostal nā aʻalolo. gland kino i ka convex discoid kinona, waihoʻoluʻu maʻamau haikea a pink, ao hionapāʻili, ka awelika anawaena o ka waihona ipu, he 10-13 knm umauma kaikamahine i ka awelika kaumaha o 150-200 g. a me ka lactation -, 400-900, o ka Y loa ola kaikamahine i hoʻokino gland hemisphere a me ka mea uprugimi.Stroenie umauma nui, shape a me ka wahi i kanaka, 'ano a me nā hiʻona.

Ka 'ole o ka umauma a me kona'anatomia

Women ka umauma i i mai o na keena e paka waiu, a i ohi ia ma na lobules. Mai kēlā kanaka slices haalele nō kahawai, a ua hui pū me nā Hoʻohana a pau i loko o Hoʻohana me ka maʻi leki uea ma i i hui a pau maʻi uuku ducts.

Like radially hooponopono i pili i ka teat, a ua kaawale mai kekahi i kekahi adipose'aʻaʻa. Kēlā me kēia kaʻana like 'ana gland ua hoʻokino e like me kaʻohana a me ke apex ma ka nipple, kahi e wehe i ka excretory leki uea. Ducts i ka nipple widen, ho okumu i kekahi nō sinuses. Hana ua kapaia ka wahi a puni ka nipple ka areola, a me ka mea uuku puʻu ma luna o ka mea, - ka mea, Aloha hou glands. Ka 'ole o ka umauma i loko o na wahine kekahi, mai kane gland' ole.

I ka ulu ana o ka mammary glands ua lawe mai i ke aloha i ka prolactin (ka hōmona o ka anterior pituitary) a me ka ovary hormones. Manawa prolactin lactation ia lŘlŘ. Ma ka hapa mua o ka hāpai keiki umauma, piʻi pū me ka nui, e like me ia lŘlŘ i loko o ka lua o ka hapalua o ka ulu ana o epithelial secretory aayoaeuiinoe partite aeee i komo o ka alveoli. I ka pau ana o hāpai keiki, a no kekahi mau lā ma hope o ka hānau maoli ka secretion a produces yellowish, manoanoa hanai aku ia wai i kapa colostrum. A laila, i ka loli i ka haku mele 'ana o nā secretions, e lilo hou wai a hana mau, a pee waiu. Ma ka pau ana o ka ai ana au, ka waiu? Iecaianoaaiiuo emi a me ka mahana, a hiki i ka kekahi hāpai keiki.

Umauma hooulu ana i na kaikamahine ia lŘlŘ i puberty ma waena o nā makahiki o 10-15 makahiki. Ke kaʻina kānāwai me ka ulu ana o ka nipple a me ka areola peripapillary laila, hoʻomaka umauma ka ulu ana i loko o kekahi mau. Umauma ma nā wāhine ua ulu no ka manawa lōʻihi, a mahope loaa umauma nui ka hanai ana i ke keiki wale nō ma hope. Ke penultimate ke kahua o ka ulu ana o ka umauma kīnā i ka makahiki o 15-17 makahiki.

Mammary gland - labile hui, e like me ka uterus ua loli ana e cyclical ka hoʻololi 'ana. Mamua o ka hoouka kaua ana o menses ia lŘlŘ ka hoʻonuiʻana o nā glands, nā'aʻaʻa hu nui ae la, me ka hao i edematous a me ka friable. Ma hope iho o ka pau ana o ka menstruation, mau symptoms nalo. I kulike ai me ka makahiki paha umauma ua maheleia i 4 ano.

1. Iron kaikamahine a ka wahine 20-25 makahiki. Ke mammary gland i kaʻaʻahu 'ole, ka waiu ducts imperceptible premammarnogo makahiki laula o 5 mm o.
2. Cancer i na wahine ma waena o nā makahiki o 25 a me 40 o functionally kaila. i hoalaala ia kona nō ala me ka epithelium, mau ulu ma luna o ka pā pōhaku, aia no na lala me ka maʻi secretory vesicles. Ka 'ole o ka glands loli aʻe ma muli o ke cyclical loli.
3. Mammary gland menopause. Ma premenopausal glandular'aʻaʻa ua dissipated i loko o ka palapala o ka mokupuni liʻiliʻi i loko o ka glandular triangle, a i hookaawale, mai ka adipose'aʻaʻa kihapai. Me ka makahiki, i ka nui o glandular parenhim emi umauma ua kōkō. Fibrous'aʻaʻa atrophies.
4. Mammary gland postmenopausal wahine. Ma menopausal loli ma ka umauma i irreversible glandular'aʻaʻa nalo loa, ka mea displaces momoma'aʻaʻa.

I haiia ae maluna,, me ka 'ole o ka umauma hilinaʻi nui ma luna o kona mau makahiki, kiʻekiʻe o? Acaeoey o ka wahine nā loko, mai ka pae ana o ka menstrual kalapona o na wahine, hormonal kūlana haʻahaʻa, lōʻihi like' ole o ka hāpai keiki, a lactation. Makahiki o ka papa kuhikuhiE ololi e hoʻoholo i ka 'ole type glands. Akā, aka hoi, he mea he kanaka oko a ma ka ka ho'ēmiʻana, a me ka hooulu ana o glandular hehee wale, a i paa ma ka alimentary, endocrine a me nā aʻe.
