Izwi rokuti mammary rinoratidzira mazamu, kunyanya, mazamu emukaka muzamu. Izwi rokuti mammal rinotorwa kubva muzwi rinonzi mammary uye rinoshandiswa kuratidza mhuka dzinodyisa vana vavo kuburikidza nehutachiwana hwekaka dzemwana (mhou dzine mazamu emakumbo mumakumbo avo.)
Mune mamwe mazwi, mazino emadzimai echikadzi ndiwo mazamu. Mamwe mazwi achishandisa mammary anotsanangura zvivakwa zvinowanikwa mukati mezvinyorwa zvemammary kana mazamu.
Semuenzaniso, izwi rokuti mammary duct ectasia raizotaura nezvehutano hunoitika mumuzamu wepamu, munyaya iyi, inoputika uye yakavharwa mukaka.
Tsanangudzo ye Epithelial Cells
Epithelial cells dzinotsanangurwa semasero kana tissue epithelium - tsvina yakawanda yezvigunwe zvinovhara kana kutarisa pamusoro pezvibhakera kana mumiriri mukati memuviri. Apo epithelial cells dzinenge dzakaipa (dzinosangana nekenza) dzinoumba matumbo ayo anonzi kanotoma. Inenge 80 muzana yekenza mumuviri womunhu ndiyo carcinomas.
Kuzviisa Pamwe
Kuisa tsanangudzo pamwe chete, mammary epithelial cells ari masero muhutete hwakatsetseka hwehupfeko hunopfeka uye hunoisa pamusoro pemukaka wemukaka muzamu. Iko kune mahara akawanda mukati mejeri imwe neimwe inoshandura mukati ma15 kusvika ku20 lobes zvezamu pavanenge vachienda kumucheto wechiko. Kune mhando dzakasiyana dzemamamita epithelial cells. Myoepithelial uye luminal epithelial cells ari maviri anowanikwa mumucheka wemukaka (ona mufananidzo).
Kukosha
Mumufananidzo, unogona kuona kuti mammary epithelial cells anowedzera sei mukaka wemukaka. Dambudziko rinomuka apo masero aya "haafi" uye anokura pasina kumira. Nhanho yekutanga yekuchinja kwekenza inonzi ductal carcinoma in situ yezamu (kana DCIS,) chirwere umo kenza inogumira mukati memharayi uye haina kupararira kumatunhu akakomberedzwa.
Panguva ino, masero haana kupararira mberi kwemuviri wepasi uye anonzi "pre-cancerous."
DCIS haisi kugara ichienda kune kenza, asi zvinosuruvarisa, zvinowanzoitika.
Apo masero aya asina kukanganisa anoputika nepamuviri wepasi - uye anopinda kana kupinda mukati mimwe mishonga - mamiriro acho anozozivikanwa sekusava nekenza kanema yepraductal yepamu - rudzi rwakanyanya kunyanya rwekenza yemazamu.
Kutumidzwa: e-pu-THEE-lee-al
Uyewo Anozivikanwa Se: Mammary epithelial cells, mazamu epithelial cells
Mienzaniso: Masero epine epithelial anowanikwa mumakumbo uye maziso ehepa rako, uye masero aya anobereka mukaka wemvere. Zvizhinji zviitiko zvekenza yebonde zvinotangira epithelial masero.
