What is mandibular symphysis?
Mandibular symphysis is an area of the lower jaw where two halves that contain the jaw connection or articulate. This intersection line is named after the clinical term of the lower jaw called the mandible. Mandibular symphysis is also known as the symphysis of menti .
The symphysis is a term given to the locations that connect with two bones, thus forming a middle line. In most cases, the symphysis is ampharthrotic, which means it is slightly movable, which is possible by attaching fibrocartilage. In the case of mandibular symphysis, however, bones are completely fused and cannot move at all.
In particular, the mandibular symphysis has a weak comb, which is the result of its work during the first years. The function is found on the outer surface of the jaw, in the middle of an area that forms a human chin. The mandibular symphysis separates at its base as it travels down and closes a triangular projection called mental protuberance. This part of the jaw has a depressive base with edging heights that they createMental tubercul.
On each side of the mandibular symphysis is a criminal fossa. This feature is thus named because it is depressed immediately below the area where the jaw carries the lower incisors, which are first teeth in humans and are used to cut food. It serves as the origin of mentalis, a muscle located at the tip of the chin, which is responsible for pushing the lower lips for the face of demonstrating displeasure or doubt. It also carries a small part of orbicularis oris, a muscle that surrounds the mouth and is used for wrinkle and closure, so it is necessary to play tools such as flute or pipe.
two muscles come from mandibular symphysis. Genohyoid is a narrow muscle that leads from the chin to the hyoid bone of the domestic neck line. The other muscle, genioglossus, also starts from the chin, but ends in the tongue.
Mandibular symphysis is known as one of the most important symphos in the body. Another big symphysisIt is a protective symphysis that connects to the top of the hair in the pan. Another symphysis of Sakrococcygeal is also called the articulation of Sacrum and Coccyx: named after parts of the vertebral column, which begins and ends. The term "pelvic symphysis" is given by a combination of public symphysis and ischiatic symphysis, which is a fusion point of the lower and rear of the hip bone.
