Human Fetal Head Week 12

Selected medial head (12 weeks) view showing key features of head musculoskeletal and neurological development. 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.

This mid-line section through the fetal head shows features of the developing skull and the brain, face and mouth.

Neural System

brain and brainstem.
lamina terminalis (site of anterior neuropore closure).
fourth ventricle.
pituitary sitting in the sella turcica.

Musculoskeletal System

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.
