The temporomandibular joint (TMJ), pain, and how to fix it
The TMJ consist of six movements; elevation, depression, protraction, retraction, lateral excursion, and medial excursion. During chewing, the jaw is protracting (moving forward) and retracting (moving backward). When opening the mouth, our mandible depresses, and our mandible elevates when closing our mouth.
Protrusion, Retrusion, and Excursion Anatomy
Excursion can occur in either direction, and anatomists use directional terms to specify the type of excursion. When the mandible moves to either the left or right, it's moving away from the body's midline, so it's called lateral excursion. When the mandible moves closer to the midline of the body, it's called medial excursion.

rotation) of the mandibular condyle, while lateral excursion occurs with ipsilateral rotation and contralateral translation of the mandibular condyles.8 Restoration of these normal accessory motions and joint mechanics is important in the rehabilitation of the TMJ in order to restore functional movements of the jaw.
The Temporomandibular Joint
The lateral pterygoid muscle is responsible for protrusion (assisted by the medial pterygoid), and the posterior fibres of the temporalis perform retraction. A lateral movement (i.e. for chewing and grinding) is achieved by alternately protruding and retracting the mandible on each side. Elevation and Depression. The lower part of the joint ...
Anatomy, Head and Neck, Mastication Muscles
The primary muscles of mastication (chewing food) are the temporalis, medial pterygoid, lateral pterygoid, and masseter muscles. The four main muscles of mastication attach to the rami of the mandible and function to move the jaw (mandible). The cardinal mandibular movements of mastication are elevation, depression, protrusion, retraction, and side to side movement. To augment the process of ...

Lateral: 8 to 12 mm. Protrusive: 8 to 12 mm. Opening Movements. Place the notch of the range of motion scale on the midline of the mandibular centrals, and take the following three measurements: Comfort: ask the patient to open "comfortably without pain.". Active: ask the patient to open as wide as they can even if it hurts.
Temporomandibular joint (TMJ): Anatomy and function
The temporomandibular joint (TMJ) is a hinge type synovial joint that connects the mandible to the rest of the skull.More specifically, it is an articulation between the mandibular fossa and articular tubercle of the temporal bone, and the condylar process of the mandible.Even though the TMJ is classified as a synovial-type joint, it is atypical in that its articular surfaces are lined by ...
TMJ Movements
TMJ Movements. Normal movements of the jaw during function, such as chewing, are known as excursions. There are two lateral excursions ( left and right ) and the forward excursion, known as protrusion, the reversal of which is retrusion. When the jaw is moved into protrusion, the lower incisors or front teeth are moved so that they first come ...
9.5 Types of Body Movements
For the mandible, protraction occurs when the lower jaw is pushed forward, to stick out the chin, while retraction pulls the lower jaw backward. (See Figure 9.13j.) Depression and Elevation. Depression and elevation are downward and upward movements of the scapula or mandible. The upward movement of the scapula and shoulder is elevation, while ...
What is lateral excursion?
Simply put, lateral excursion is when the mandible moves to one side. But the mechanism behind this is not as simple as it sounds. The mandible is capable of two movements if we take the condyle as the hinge: rotation and translation. Imagine a vertical and horizontal axis passing through the condyles. The movement of the mandible with respect ...

Muscles of mastication: Anatomy, functions, innervation
The medial pterygoid muscle is a quadrangular muscle situated in the infratemporal fossa. It is composed of two heads that have two sets of origins. The larger deep head arises from the medial surface of the lateral pterygoid plate of the sphenoid bone and the adjacent pyramidal process of palatine bone.; The smaller superficial head originates from the tuberosity of the maxilla.

The Muscles of Mastication
There are four muscles: Masseter. Temporalis. Medial pterygoid. Lateral pterygoid. The muscles of mastication develop from the first pharyngeal arch. They are therefore innervated by a branch of the trigeminal nerve (CN V), the mandibular nerve. In this article, we shall look at the anatomy of the muscles of mastication - their attachments ...
