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.
