Study Notes
Zygomatic Bones
- Contribute to the rim and lateral wall of the orbit
- Form part of the zygomatic arch
- Located in the upper outer part of the face
- Form the prominence of the cheek and part of the lateral wall of the orbit
- Articulates with the sphenoid, frontal, temporal and maxillary bones
Lacrimal Bones
- Smallest and most fragile bone in the face
- Situated at the front part of the medial wall of the orbit
- Articulates with the zygomatic arch of the temporal bones
Palatine Bones
- Contribute to the walls of three cavities:
- Floor and lateral wall of the nasal cavity
- Roof of the mouth
- Floor of the orbit
Nasal Bones
- Vary in size and form between different individuals
- Located side by side in the middle and upper part of the face
- Form "the bridge" of the nose
Inferior Nasal Conchae
- Extends horizontally along the lateral wall of the nasal cavity
- Consists of a lamina of spongy bone, curled upon itself like a scroll
Anatomical Position
- Subject stands erect facing the observer
- Upper extremities are placed at the sides
- Palms of the hands are turned forward
- Feet are flat on the floor
Terminology
- Patient aspect: The view of the patient from the front
- Anterior aspect: The view of the patient from the front
- Posterior (dorsal) aspect: The view of the patient from the back
- Lateral aspect: Any view of the patient from the side
- Medial aspect: The side of a body part closest to the midline
Maxillae
- Contains the lacrimal sac and the nasal-lacrimal duct
- Important for facial structure and the formation of the roof of the mouth
