What is mandibular ramus?
mandibular ramus is part of the jaw or jaw. When bones that stretch from the underside of both ear and give rise to the lower teeth, consist of the body, which is a horizontal part passing through the chin, and Ramus, a vertical section under each ear. The mandibular ramus serves as a bridge that attaches the jaw to the time bone of the skull over the temporomandibular (TMJ) joint, the joint that opens and closes the mouth. This is also the place where the muscles of the master are joined, a large muscle used for chewing or chewing.
As a vertical part of the jaw, MANMUS is on both sides of the jaw. It comes from both ears channels extends down to the lower side of the jaw. The mandibular ramus is four -sided, longer from top to bottom than the wide and flat shape. It is also equipped with two bone projections called processes that protrude up from the front and rear corners of the bone, which form a U -shaped space, known as the mandibular notch.
processes based on the top of the mandibular ramus are referred to as coronoid and condyloid processes. There is a coronoid process in front of the mandibular notch or towards the front of Ramus. This projection is a place where the muscles of the master and temporalis are attached at the bottom ends, both muscles of chewing. Behind the mandibular notch and just in front of the fierce channel is a condyloid process, a larger of both projections. The condyloid process is the lower surface of the TMJ joint and is thus named for its oval shape.
as one of the only moving joints in the body that has a joint disk between the articulated bones, TMJ has an unusual classification of joints. It is referred to as gontymoarthrodial joint, nod to the fact that the lower part of the joint, the troop between the condyloid process of the mandibular ramus and the joint disk, acts as a gontymoid or a hinge joint. In the joint of the joint, the bone rotates against its joint surface as a door hinge to move in two directions whatIt allowed the jaw to reduce and lift. Part of the joint between the disc and the time bone above it, on the other hand, it acts as an arthrodial or flat joint. This means that both surfaces slide around them in motion known as a translation that causes the entire jaw to move forward and down as the mouth opens.
