Human Fetal Head Week 12

This medial (mid-line) section through the fetal head (12 weeks) shows features of the developing skull and the brain, face and mouth. Note extensive nasal cartilage, nasal conchae, pituitary, secondary palate, oral cavity, tongue, mandible, hyoid, choana, oropharynx. Also note the developing tongue musculature and its mandibular attachment site.

Neural

brain and brainstem.

lamina terminalis (site of anterior neuropore closure).

fourth ventricle.

pituitary sitting in the sella turcica.

Musculoskeletal

cartilage - skull septum of the nose.

bone - upper respiratory ossifying nasal concha.

bone - hard palate roof of mouth.

cartilage - soft palate back of mouth.

cartilage - base of skull and vertebra.

muscle - tongue, attached to mandible, note foramen cecum.

bone - mandible.
