Akpa amniotic
Akpa amniotic, nke a na-akpọkwa akpa mmiri ma ọ bụ membrane, bụ akpa ebe nwa e bu n'afọ na nwa e bu pụta na-etolite na amniotes. [1][2][3]Ọ bụ ihe dị nro ma sie ike nke na-egbuke egbuke nke na-ejide nwa ọmụmụ na-eto eto (na nwa e bu n'afọ) ruo obere oge tupu a mụọ ya. Ihe dị n'ime membranes ndị a, amnion, na-ekpuchi Oghere amniotic, nke nwere Mmiri amniotic na embryo. Mkpịsị aka dị n'èzí, chorion, nwere amnion ma bụrụ akụkụ nke Placenta. N'akụkụ dị n'èzí, a na-ejikọta akpa amniotic na akpa yolk, allantois, na site na eriri umbilical, Placenta.[4]
Akpa yolk, amnion, chorion, na allantois bụ mpempe akwụkwọ anọ extraembryonic nke dị n'èzí embryo ma na-etinye aka n'inye ihe oriri na nchebe maka embryo na-eto eto. [5]Ha na-esite na mkpụrụ ndụ dị n'ime; nke mbụ na-esonye bụ akpa yolk na-esote amnion nke na-eto n'elu embryo na-eto eto. Amnion na-anọgide na-abụ ihe dị mkpa extraembryonic membrane n'oge niile a na-amụ nwa. Membrane nke atọ bụ allantois, nke anọ bụ chorion nke gbara embryo gburugburu mgbe ihe dị ka otu ọnwa gasịrị ma mesịa jikọta ya na amnion.[6]
Amniocentesis bụ usoro ahụike ebe a na-anwale mmiri sitere na akpa n'oge mmepe nwa, n'etiti izu 15 na 20 nke ime ime, iji mee ihe na nchọpụta tupu amụọ nwa chromosomal abnormalities na ọrịa nwa.[7]

Oghere amniotic gbara ya gburugburu na membrane extraembryonic, nke a na-akpọ amnion. Ka mbido nke blastocyst na-aga n'ihu, obere oghere na-apụta na embryoblast, nke bụ primordium nke oghere amniotic. N'oge na-adịghị anya, amniogenic (amnion-forming cells) a na-akpọ amnioblasts kewapụrụ na epiblast ma kwụnye amnion, nke na-ekpuchi oghere amniotic.[8]

Na mbido izu nke abụọ, oghere na-apụta n'ime mkpụrụ ndụ dị n'ime, mgbe ọ na-ebuwanye ibu, ọ na-aghọ oghere amniotic. Ala nke oghere amniotic sitere na epiblast. Epiblast na-agagharị n'etiti epiblastic disc na trophoblast. N'ụzọ dị otú a, mkpụrụ ndụ epiblastic na-agagharị n'etiti embryoblast na trophoblast. A na-emepụta ala site na epiblast nke na-emesị gbanwee na ectoderm ebe mkpụrụ ndụ ndị fọdụrụnụ nke dị n'etiti embryoblast na trophoblast a na-akpọ amnioblasts (mkpụrụ ndụ dị larịị). A na-esikwa na epiblast nke a na-agbanwe ka ọ bụrụ ectoderm. [citation needed]
Akpa amniotic na ihe jupụtara na ya na-enye mmiri nke gbara nwa ahụ gburugburu ma na-ekpuchi nwa ahụ. Ọ bụ ebe mgbanwe nke ihe ndị dị mkpa, dị ka oxygen, n'etiti eriri umbilical na nwa e bu n'afọ.

Epiblast na-emepụta ala nke oghere amniotic ma na-aga n'ihu na amnion. Hypoblast na-emepụta elu nke oghere exocoelomic ma na-aga n'ihu na mpempe akwụkwọ exocoelomtic dị nro. Membrane a tinyere hypoblast na-emepụta akpa yolk bụ isi. Diski embryonic dị ugbu a n'etiti oghere amniotic na akpa yolk bụ isi. Mkpụrụ ndụ sitere na yolk sac endoderm na-emepụta akwa nke anụ ahụ na-ejikọta, extraembryonic mesoderma nke gbara amnion na yolk bag gburugburu. [citation needed]

N'oge ọrụ nwa, akpa amniotic ga-agbaji ka a amụọ nwa ahụ. A maara nke a dị ka rupture of membranes (ROM). Dị ka o kwesịrị, ọ na-eme na mberede n'oge zuru ezu ma ọ bụ n'oge ma ọ bụ na mmalite nke ọrụ.
