Document Summary
Read the following excerpt if you are puzzled by the cephalic furrow (& based on the description in the text, my guess is that you probably are puzzled): During drosophila gastrulation, the embryo is transformed from a regular array of morphologically identical cells, organized in a single layer, into a complex array of cell groups. Although the cf is a prominent morphological feature of the change cell shape and move together in a characteristic, predetermined manner (review by costa et al. , 1993). Two invaginations, the ventral and cephalic furrows, represent the first morphological manifestations of cell fate and differentiation programs. The ventral furrow (vf) invaginates along most of the ventral midline, bringing the mesoderm and possibly part of the anterior endoderm primordium into the interior of the embryo. Cephalic furrow (cf) invagination takes place laterally on both sides of the embryo, near its anterior end. Unlike vf formation, the cf is only transient.
