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.
