Fetal Head (12 weeks)

Medial view, stained for bone (Histology_Stains#Alizarin_Redalizarin red) and cartilage (alcian blue)

In this medial (internal) view, note the distribution of cartilage from the nasal region through the base of the skull to the atlas/axis (with new bone forming). See also the original Meckel's cartilage within the newly forming bony mandible.

Note: Cartilage in the neck where the hyoid bone will eventually form. Meckel's cartilage visible in the medial view within the newly forming bone.
