Dentistry · Oral histology and anatomy: embryology of the primary palate

Sample item

Which embryonic structure forms the primary palate, the part of the hard palate in front of the incisive foramen that carries the upper incisors?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Intermaxillary segment from fused medial nasal prominences

The medial nasal prominences fuse in the midline to form the intermaxillary segment, which gives the philtrum, the premaxillary part of the maxilla with the four incisors, and the primary palate. The secondary palate forms later from the palatal shelves.

Option by option

  • A. Intermaxillary segment from fused medial nasal prominences (correct)

    Correct. Fused medial nasal prominences give the intermaxillary segment and primary palate.

  • B. Nasal septum of the frontonasal prominence

    The nasal septum separates the nasal cavities and does not form the palate in front.

  • C. Lateral nasal prominences

    The lateral nasal prominences form the alae of the nose.

  • D. Palatal shelves of the maxillary prominences

    The palatal shelves form the secondary palate behind the incisive foramen.
