-{Which of the following best describes the buccopharyngeal membrane structure:
+{Which of the following sequences of embryonic disc mesoderm is most correct:
 |type="()"}
-- a ventral surface indentation in the early embryo head
+- &nbsp; lateral to medial: extraembryonic - lateral plate - intermediate - paraxial
-- endoderm layer of the foregut
+- &nbsp; lateral to medial: lateral plate - paraxial - intermediate - axial
-- ectoderm layer of the epidermis
++ &nbsp; medial to lateral: notochord - somites - intermediate - lateral plate
-+ ectoderm and endoderm
+- &nbsp; medial to lateral: paraxial - axial - intermediate - cardiac
-- none of the above is correct
-|| The buccopharyngeal membrane ({{oral membrane}}) consists of {{ectoderm}} and {{endoderm}} together. Endoderm layer of the foregut
+||The [[E#extraembryonic mesoderm|extraembryonic mesoderm]] is outside the embryonic disc. Intermediate mesoderm is outside the paraxial layer. Cardiogenic mesoderm is a region of prechordal splanchnic mesoderm. Note - how I always mispronounce "paraxial" as "para-axial", it's a bad habit of mine, the correct pronunciation is "par" then "axial".
- and ectoderm layer of the epidermis are partially correct. The ventral surface indentation in the early embryo head is the stomedeum, on the floor of which is located the {{buccopharyngeal membrane}}.
