Fetal Head (12 weeks)

Image shows the distribution of skull bone:

  1. forming from cartilage (chondrocranium, endochondrial ossification).
  2. forming directly mesenchyme (intramembranous ossification).

Medial view, stained for bone (alizarin 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).

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