What articulates with the mandible?
temporal bone
What does the mandibular process articulate with?
At the superior aspect of each ramus, the coronoid and condylar processes articulate with the temporal bone to create the temporomandibular joint which permits mobility. Other than the ossicles of the ear, the mandible is the only skull bone that is mobile, allowing the bone to contribute to mastication.
What is the mandibular fossa?
The mandibular fossa or glenoid fossa is the smooth concave articular surface formed by both the squamous and petrous parts of the temporal bone. It forms the superior articular part of the temporomandibular joint and lodges the condyle of mandible.
What does the mandibular condyle articulate?
Mandibular condyle – rounded head of the condylar process; articulates with the mandibular fossa of the temporal bone at the temporomandibular joint (TMJ).
What is the function of the mandibular condyle?
The mandibular condyle is actively involved in endochondral ossification. The condylar cartilage is an important growth site in the mandible, contributing to the elongation of the mandibular ramus.
Why is the mandibular fossa important?
The mandibular fossa is the cavity in the temporal bone that enables interaction with the mandibular condyle. The mandibular fossa of the temporal bone borders with articular tubercle in the front and is separated from the external acoustic meatus by the tympanic part of the bone on the backside.
Are there two mandibular fossa?
The fossa is divided into two parts by a narrow slit, the petrotympanic fissure (Glaserian fissure). It is also referred to as the glenoid fossa in dental literature.
What is the function of Fossa in bones?
Fossa – A shallow depression in the bone surface. Here it may receive another articulating bone or act to support brain structures. Examples include trochlear fossa, posterior, middle, and anterior cranial fossa.
What is mandibular process?
The mandibular process is an embryological structure which gives rise to the lower jaw elements (e.g., mandible bone) of the developing face.
What is the most common cause of restricted mandibular movement?
spasm of the muscles of mastication, is the most common cause of restricted mandibular movement.
What does mandibular mean?
the lower jaw
What is the lower jaw bone called?
mandible
Which jaw is movable in human body?
What is the difference between jaw and mandible?
As nouns the difference between mandible and jaw is that mandible is the lower jaw, especially the lower jawbone while jaw is one of the bones, usually bearing teeth, which form the framework of the mouth.
Do humans have one or two jaws?
The left and right halves of the lower jaw, or mandible, begin originally as two distinct bones, but in the second year of life the two bones fuse at the midline to form one. The horizontal central part on each side is the body of the mandible.
Which is the strongest muscle of mastication?
masseter muscle
