Human Female Fetus - Oral Cavity (10 week)

Large image version of plane D, close to midline (Stain - Haematoxylin Eosin) 0.7 mm scale bar.

Tongue Development

Section shows detail of the tongue muscular structure, formed from occipital somites. The genioglossus (fan-shaped muscle) lies between the tongue and mandible and is innervated by the hypoglossal nerve (CN12). Poking out your tongue is a test of this nerve. Note the tongue connective tissue and vasculature are derived from neural crest.

The mandible is developing by intramembranous ossification beside the large Meckel's cartilage template.

Also shown in the oral cavity region are the lips and palate.

Not the the hyoid in the neck region.
