Anterior (ventral)
The back of the body.
Posterior (dorsal)
Toward the head and away from the feet.
Superior
Away from the head and towards the feet.
Inferior
Tip or pointed end
Apex
This divides teh body into right and left
Median (midsaggital)
This is parallel to the median plane
Saggital
This divides the body into anterior and posterior parts.
Frontal (coronal)
Divides the body into superior and inferior parts.
Horizontal
Median is for the ____ while mesial is for the _____.
- Body
- Teeth
Far from the medial plane.
Lateral
Area farther from the medial plane.
Distal
Area closer to the medial plane.
Proximal
Same side
Ipsilateral
Opposite side
Contralateral
Located toward teh surface.
Superficial
Inward, away from body surface.
Deep
Inner side of the wall of a hollow surface.
Internal
Outer side of the wall of a hollow surface.
External
Cuth through the median plane.
Medsagittal section (median section)
Cut through any frontal plane.
Frontal section

Transverse
What are the 12 regions of the head?
- Frontal region
- Parietal region
- Temporal region
- Auricular region
- Zygomatic region
- Occipital region
- Orbital region
- Infraorbital region
- Nasal region
- Oral region
- Buccal region
- 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
