What muscle is lateral to the ramus of the mandible?
The masseter muscle is lateral to the ramus of the mandible.
What muscle Protrudes the mandible?
lateral pteregoid
In Bennett movement there is movement of which condyle?
the movement of mandible toward lateral causes movement in both right and left condyles. For example, if one moves one's mandible (lower jaw) toward right, the right conlye moves laterally and the left goes downward, forward, and medially, so the left condyle is defined as nonworking and the right condyle as working. the movement of nonworking condyle,in this example left condyle, forms an angle between sagittal plan and direction of nonworking condyle, which is called Bennett angle.
What muscle helps the platysma lower the mandible?
Lateral pterygoid (HOLES book, pg 155 part a )
What muscles is responsible for the protraction of the mandible?
The lateral pterygoid muscle has a triangular shape, with two heads; superior and inferior. It has horizontally orientated muscle fibers, and is the major protractor of the mandible.
What is Bennett movements in teeth?
the movement of mandible toward lateral causes movement in both right and left condyles. For example, if one moves one's mandible (lower jaw) toward right, the right conlye moves laterally and the left goes downward, forward, and medially, so the left condyle is defined as nonworking and the right condyle as working. the movement of nonworking condyle,in this example left condyle, forms an angle between sagittal plan and direction of nonworking condyle, which is called Bennett angle.
Where does the masseter temporalis and pterygoids all insert?
The masseter inserts on the mandible, specifically on the angle and ramus. The temporalis inserts on the coronoid process of the mandible. The lateral pterygoid inserts on the condyloid process of the mandible, while the medial pterygoid inserts on the angle of the mandible.
What is the muscle called that is located between the condyle of the mandible and the the greater wing of the sphenoid?
Lateral Pterygoid
What type of synovial joint movement raises the mandible?
Elevation is the synovial joint movement that raises the mandible. It is typically carried out by the temporalis and masseter muscles.
Which muscles helps to open the mouth and depress the mandible?
lateral pterygoid, digastric, mylohyoid andgeniohyoid muscles
What nerve causes lateral movement of the eye?
abducens nerve
What causes primary lateral sclerosis?
Motor neuron diseases like primary lateral sclerosis develop because the nerve cells that normally control the movement of voluntary muscles degenerate and die.
