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 Produces the chewing movements of the mandible?

The chewing movements of the mandible are primarily produced by the coordinated action of several muscles, including the masseter, temporalis, and pterygoid muscles. These muscles work together to elevate, depress, and move the mandible side to side, allowing for effective grinding and crushing of food. The movements are controlled by the trigeminal nerve (cranial nerve V), which transmits signals between the brain and the muscles involved in mastication. Additionally, the temporomandibular joint (TMJ) facilitates the mobility of the mandible during these movements.


Is medial pterygoid and masseter muscles of mastication?

Yes, both the medial pterygoid and masseter muscles are muscles of mastication. The masseter is primarily responsible for elevating the mandible, contributing to chewing. The medial pterygoid also assists in elevating the mandible and allows for side-to-side movement during chewing. Together, these muscles play a crucial role in the process of mastication.


The mandible elevated by what?

The mandible is elevated by the action of the temporalis, masseter, and medial pterygoid muscles. These muscles work together to close the jaw and elevate the mandible during activities such as chewing and biting.


Prime mover to raise the mandible?

The temporalis and masseter muscles are the primary muscles responsible for raising the mandible (lower jaw) during the process of chewing or biting. These muscles work together to produce the necessary force to close the mouth and elevate the mandible.


What is the only moveable bone in the face?

The mandible, also known as the lower jaw bone, is the only moveable bone in the face. It is unique in that it can move up and down, as well as side to side, enabling actions such as chewing and speaking.

What is the bone that is known as your jaw bone?

A person has two jaw bones. One upper jaw bone called the maxilla and the lower bone called the mandible. The maxilla doesn't move but the mandible does. The muscle (masseter) that closes the two is one of the strongest muscles in the human body.


Which of the jawbones move?

Mandible


What is the you shape bone lying just below the mandible?

Hyoid bone. It supports the tongue and serves as an attachment for muscles that move the tongue and function in swallowing.


What is the ascending part of the mandible?

The ascending part of the mandible is the vertical portion of the mandible bone that extends from the mandibular angle to the coronoid process. It forms the posterior border of the ramus of the mandible and provides attachment for muscles involved in chewing and jaw movement.


Which muscles helps to open the mouth and depress the mandible?

lateral pterygoid, digastric, mylohyoid andgeniohyoid muscles
