Questions and Answers

Match the TMJ compartments with their functions:

Lower joint compartment = Rotational or Hinge movement Upper joint compartment = Translational or Gliding movements Disk division = Smooth gliding function Articular disc = Involved in both compartments

Match the terms related to TMJ with their descriptions:

Rotational movement = Opening and closing movements Translational movement = Sliding the lower jaw forward or side to side Articular disk = Divides the compartments Mandible = Forms the lower joint compartment

Match the types of movement with their corresponding TMJ compartment:

Hinge movement = Lower joint compartment Gliding movement = Upper joint compartment Elevation/Depression = Translational movement Protrusion/Retrusion = Transitional movement

Match the anatomical structures with their roles in TMJ:

<p>Articular surfaces = Facilitate smooth gliding function Lower compartment = Involves the mandible Upper compartment = Involves the temporal bone Disk = Supports compartment division</p> Signup and view all the answers

Match the definitions to the TMJ components:

<p>Rotational = Movement facilitating opening and closing Translational = Movement allowing jaw sliding Articular disc = Structure aiding joint function Smooth gliding = Outcome of compartment division</p> Signup and view all the answers

Study Notes

TMJ Structure and Function

The temporomandibular joint (TMJ) allows for complex jaw movements critical for chewing and speaking.
The articular disc divides the joint into two compartments: the upper and lower, facilitating smooth motion.

Lower Joint Compartment

Composed of the mandible and the articular disc.
Responsible for hinge-like (rotational) movements, primarily associated with opening and closing the mouth.

Upper Joint Compartment

Formed by the articular disc and the temporal bone.
Facilitates translational (gliding) movements, enabling the jaw to slide forward or side to side, essential during jaw elevation, depression, and movement in protrusion or retrusion.
