oropharyngeal membrane

A transient ectodermal membrane formed in embryos where the anterior aspect of the primitive gut contacts the abdominal wall, separating the depression of the stomadeum from the primitive pharynx. The membrane completely disappears by the 4th week, leading to communication between the stomadeum and pharynx.
