The mandible has two main holes , found on both its left and right sides: The mandibular foramen, is above the mandibular angle in the middle of each ramus. The mental foramen sits on either side of the mental protuberance (chin) on the body of mandible, usually inferior to the apices of the mandibular first and second premolars. As mandibular ...
The angle of the mandible refers to the angle created by the arrangement of the body of the mandible and the ramus. Angle fractures are defined as those that involve a triangular region bounded by the anterior border of masseter muscle and an oblique line extending from the lower third molar (wisdom tooth) region to the posteroinferior ...
Diagram showing left medial and lateral pterygoid muscles. Part of the zygomatic arch and the ramus of the mandible have been cut away. The pterygomandibular space lies between the lateral surface of medial pterygoid and the medial surface of the mandibular ramus.
Anatomical landmarks of the mandible from a right lateral view. Mandible is a movable solitary bone forming the lower jaw. [12] It is composed of a mandibular body and two mandibular rami (singular: ramus [13]) on bilateral sides of the face. [14]
The forensic term for the midpoint of the mandibular angle is the gonion. The gonion is a cephalometric landmark located at the lowest, posterior, and lateral point on the angle. [1] This site is at the apex of the maximum curvature of the mandible, where the ascending ramus becomes the body of the mandible.
The mandibular nerve is one of three branches of the trigeminal nerve, and the only one having motor innervation.One branch of it, the inferior alveolar nerve, as well as the inferior alveolar artery, enter the foramen traveling through the body in the mandibular canal and exit at the mental foramen on the anterior mandible at which point the nerve is known as the mental nerve.
A transverse jaw position is known as Laterognathia. This term describes a lateral bite in the lower jaw [34] and is often associated with a unilateral crossbite at an early age [35] This can lead to bone development of an asymmetrical mandibular ramus resulting in asymmetry in the whole of the lower face. [36]
In human anatomy, the mandible's coronoid process (from Greek korōnē 'hooked') is a thin, triangular eminence, which is flattened from side to side and varies in shape and size. Its anterior border is convex and is continuous below with the anterior border of the ramus.
