Question

Buccopharyngeal present in ?

Answer 1

In anatomy, buccopharyngeal structures are those pertaining to the cheek and the pharynx or to the mouth and the pharynx.
The region where the crescentic masses of the ectoderm and endoderm come into direct contact with each other constitutes a thin membrane, the buccopharyngeal membrane (or oropharyngeal membrane), which forms a septum between the primitive mouth and pharynx. In front of the buccopharyngeal area, where the lateral crescents of mesoderm fuse in the middle line, the pericardium is afterward developed, and this region is therefore designated the pericardial area.
