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

Endocrine

  • hypothalamus
  • pituitary sitting in the sella turcica.
    • note remnant of Rathke's pouch still visible on floor of developing sella turcica (cartilage)

Skeletal System

Muscle

  • muscle - tongue, attached to mandible, note foramen cecum.
    • genioglossus muscle - attached to mandible
    • geniohyoideus muscle - attaching hyoid bone to mandible
