Depression of the mandible. What is the depression of the mandible. The Lateral pterygoid muscle is active during mastication and during mandibular movements such as protrusion forward movement of the mandible abduction depression of the mandible mediotrusion movement of the mandibular condyle towards the midline and particularly during speaking singing and clenching. The lateral pterygoid muscle functions as the sole muscle of mastication to causes depression of the mandible.
That being the case depression of the mandible is largely the result of gravity. It also assists with protrusion and side to side movement of the mandible. The research and development studies on the fuel cells Stirling engines and gas turbines must be performed for more efficiently system design.
In practical there is inadequate operational experience. Prime Moveragonist For Depression Of The Mandible 5 out of 5 based on 20 ratings. Prime Moveragonist For Depression Of The Mandible 4 out of 5 based on 12 ratings.
Stabilization of hyoid bone in swallowing by pulling hyoid bone downward. Depression of mandible when hyoid bone is stable. The digastric fossa is an oval depression on the lower internal surface of the body of the mandible on either side of the middle line for attachment of the anterior belly of the digastric muscle.
The mylohyoid line is a paired line on the inside of the mandible an oblique ridge extending from the posterosuperior to anteroinferior aspect of the body of the mandible. This muscle acts to depress mandible when the hyoid is fixed. With a fixed mandible it will elevate the hyoid and move it forward antagonist of stylohyoid Also it is active on protrusion and the ipsilateral side of lateral deviation.
The mandible is a singular bone that has a distinctive horse-shoe shape and is symmetrical on both sides. It is the moving part of the jaws when the body is engaged in the feeding process and for that reason all the muscles of mastication including the medial and lateral pterygoid muscles the temporal muscle and the masseter muscle attach to it.

Depression which depresses the mandible and opens the mouth. Rotation which produces side-to-side movements of the mandible.

LearnVisible Body - Mandible Elevation and Depression - YouTube. LearnVisible Body - Mandible Elevation and Depression. The cardinal mandibular movements of mastication are elevation depression protrusion retraction and side to side movement.
To augment the process of eating the muscles of mastication also move the mandible in a side to side motion to assist in the grinding of food. Lingual mandibular bone depressions mainly affect the posterior region of the mandible. Depressions in the anterior region are rare frequently posing difficulties in diagnosis.
The aim of this article is to present a case of an anterior lingual mandibular bone depression ALMBD that was radiograph. The anterior buccal mandibular depression ABMD an anatomic variation not previously mentioned in the dental literature is considered Its physical and radiologic configuration is evaluated and its significance in the differential diagnosis of radiolucent lesions in the anterior portion of the mandible is discussed.
