Primary Palate
Above images show face development through week 6 to week 7 (1mm scale markings).
The animation shows the early fusion of the primary palate in the human embryo between stage 17 and 18, going from an epithelial seam to the mesenchymal bridge.

This animation shows a ventral view of development of the human face from approximately week 5 through to neonate.

Selected Head Images: B4 - Choroid Plexus | B5 - Cochlea | B6 - Cochlea
Palate
The dark "pear-shaped" central structure at the top is the developing tongue. The two pale regions either side are the palatal shelves, note that they have not yet fused in the midline (failure of this process is cleft palate).
Hearing
Behind that a pale cartilagenous region (that later ossifies) encloses the structuctures of the inner ear, beside which middle ear bones are forming. On the righthand side of the head the external ear is visible. The lower half of the image shows the developing brainstem with a large ventricular space occupied in part by an extensive choroid plexus (manufacturer of cerebrospinal fluid).
