The facial artery typically crosses the inferior border of the mandible just anterior to the masseter muscle's insertion. In most instances, this crossing occurs at or in close proximity to the antegonial notch. This anatomical association has clinical relevance in various surgical procedures involving the face and mandible.
The Stafne defect (also termed Stafne's idiopathic bone cavity, Stafne bone cavity, Stafne bone cyst (misnomer), lingual mandibular salivary gland depression, lingual mandibular cortical defect, latent bone cyst, or static bone cyst) is a depression of the mandible, most commonly located on the lingual surface (the side nearest the tongue).
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...
The articular disk of the temporomandibular joint is a thin, oval plate made of non-vascular fibrous connective tissue located between the mandible's condyloid process and the cranium's mandibular fossa. Its upper surface is concavo-convex from before backward, to accommodate itself to the form of the mandibular fossa and the articular tubercle ...
In jawed vertebrates, the mandible (from the Latin mandibula, 'for chewing'), lower jaw, or jawbone is a bone that makes up the lower – and typically more mobile – component of the mouth (the upper jaw being known as the maxilla). The jawbone is the skull's only movable, posable bone, sharing joints with the cranium's temporal bones.
The pterygomandibular space lies between the lateral surface of medial pterygoid and the medial surface of the mandibular ramus. The four compartents of the right masticator space. A Temporalis muscle, B Masseter muscle, C Lateral pterygoid muscle, D Medial ptaerygoid muscle, E Superficial temporal space, F Deep temporal space, G Submasseteric ...
Translation Translation occurs in the upper TMJ compartment and provides most of the mandible's ability to open. Articular disc and condyle complex slide inferiorly on the articular eminences, allowing maximum depression of the mandible. [7] Maximal Mandibular Opening (T). Condylar heads are said to be at a maximum anterior-inferior position.
In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis (Latin: symphysis menti) or line of junction where the two lateral halves of the mandible typically fuse in the first year of life (6–9 months after birth).
