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]
