Study Notes
Bones of the Head and Face
- Frontal eminences are rounded prominences located on either side of the median line of the frontal bone, contributing to the face's warm color area.
- The supraorbital margin is the superior rim of the eye socket on the frontal bone, important for eye structure.
- The superciliary arch is found on the forehead, positioned superiorly to the median ends of the eyebrows, influencing facial contour.
- Glabella refers to an elevation between the superciliary arches above the root of the nose, serving as a landmark on the frontal bone.
- Foramen magnum is a large base opening of the skull allowing the brain to connect to the spinal cord, critical for neurological function.
- Parietal eminence is the rounded peak of the parietal bones, determining the widest part of the cranium, essential for cranial measurements.
- Squama is the thin superior part of the temporal bone, forming a portion of the lateral skull.
- Zygomatic arch, commonly known as the cheek bone, contributes to facial symmetry and structure.
- Mandibular fossa is a small oval depression on the underside of the temporal bone, where the mandibular condyle articulates.
- External auditory meatus refers to the ear canal, playing a key role in hearing and sound localization.
- Mastoid process is a round projection on the temporal bone located behind the ear, serving as an attachment point for muscles.
- The nasal cavity is the opening in the bony face bordered by the nasal bones and maxilla, essential for the respiratory system.
- Frontal process of maxilla is the ascending part of the upper jaw that protrudes beside the nasal bone, connecting to the frontal bone.
- Alveolar process forms the borders of both upper and lower jaws, containing sockets for teeth, crucial for dental anatomy.
- Palatine process composes the anterior section of the hard palate and contributes to the nasal cavity and eye orbits.
- Zygomatic process occurs where the temporal bone meets the zygomatic bone, aiding facial shape.
- Dental prognathism, also referred to as buck teeth, describes the oblique insertion of teeth, impacting dental alignment.
- Mental eminence is a triangular projection on the anterior mandible's inferior portion, contributing to jaw shape.
- Incisive fossa is the area between the mental eminence and inferior incisor teeth, important for dental structure.
- Coronoid process projects from the upper border of the ramus of the mandible, serving as a muscle attachment.
- Mandibular condyle is the rounded eminence at the articulating posterior process of the mandible's ramus, crucial for jaw movement.
- Angle of the mandible forms a bony angle marking the junction between the ramus and the body of the mandible; it signifies the widest part of the lower face.
- Bimandibular width is measured by a straight line between the two angles of the mandible, used in photographic analysis for restoration planning.
