Dental radiography. Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities . A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities ...
Orbicularis oris muscle. Inferior labial artery and superior labial artery. It is sometimes known as the kissing muscle[ 1] because it is used to pucker the lips. In human anatomy, the orbicularis oris muscle is a complex of muscles in the lips that encircles the mouth. [ 2] It is not a true sphincter, as was once thought, as it is actually ...
Panoramic radiograph. A dental panoramic radiograph, showing the maxilla and mandible, all the teeth including the " wisdom teeth ," the frontal and maxillary sinuses, the nasal cavity and the temporomandibular joint and other near by head and neck anatomy. A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.
The mandible forms the lower jaw and holds the lower teeth in place. It articulates with the left and right temporal bones at the temporomandibular joints. The condyloid process, the superior (upper) and posterior projection from the ramus, makes the temporomandibular joint with the temporal bone.
Occlusion, in a dental context, means simply the contact between teeth. More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest. Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic ...
Sagittal section of nose mouth, pharynx, and larynx. (Frenulum linguae is the topmost label at right.) The frenulum (or frenum) of the tongue, tongue web, lingual frenulum, frenulum linguae, or fraenulum[ 1] is a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the human tongue .
Mandible (insect mouthpart) Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals.
Specimens were collected from the ocean near Vanuatu in 1994, but researchers only recently identified them as a new species, a study said. Creature with ‘large’ mouth and pointy teeth found ...
