What are the 12 regions of the head?

  1. Frontal region
  2. Parietal region
  3. Temporal region
  4. Auricular region
  5. Zygomatic region
  6. Occipital region
  7. Orbital region
  8. Infraorbital region
  9. Nasal region
  10. Oral region
  11. Buccal region
  12. Mental region

This region includes teh forehead and area above the eyes. It contains the supraortibal ridge and glabella.

Frontal region

These 2 regions are located next to each other and are covered by the scalp.

Parietal and Occipital region

This region consists of the external ear (auricle, external acoustic meatus). Two featres of the external ear are the tragus and antitragus.

Temporal region

This region consists of the orbit that houses the eyeball and supporting structures. The lacrimal gland is located Here. What are the terms for the inner and outer corner of the eye.

  • Orbital region
  • Lateral canthus
  • Medial canthus

This region consists of the structures of the nose.

  • Root of the nose
  • Nasion
  • Bridge of the nose
  • Apex
  • Naris (Nares)
  • Nasal septum
  • Ala

Nasal region

This is the region inferior to the orbit and lateral to the nasal.

Infraorbital region

This region overlyes the zygomatic arch and the TMJ (where you can feel the movement on the external acoustic meatus.

Zygomatic region

This region overlyes the zygomatic arch and the TMJ (where you can feel the movement on the external acoustic meatus.

Zygomatic region

This region includes the cheeks which are formed mainly by the masseter muscles.

Buccal region

This is the sharp angle of the jaw inferior to the ear.

Angle of the mandible

This is the vertical groove from the septum of the nose to the upper lip.

Philtrum

This is where the philtrum termiantes at the upper lip.

Tubercle of the upper lip

This is where the upper and lower lips meet at the corners.

Labial commissure

This is the area between the commisures and the nose.

Nasolabial sulcus

This separates the lower lip from the chin.

Labiomental groove

This is located on the buccal mucosa opposite the maxillary 2nd molars.

Parotid papilla

Firm, pink mucosa.

Gingiva
