The TMJ (Temporomandibular Joint) is arguably the most complex joint in the body.
There are three basic types of joints in the human body, and the TMJ incorporates characteristics of all three.
1. The hinge joint, like a knee or elbow, the joint moves like a door opening and closing.
2. The ball and socket joint, like the hip or shoulder, a wide range of motion is achieved by circular motion around a central point.
3. The glide joint, like the wrist wherein motion is achieved when bones essentially glide together and apart.
The TMJ acts like a hinge joint when you simply open and close your mouth. It acts like a ball and socket joint when you chew your food, and it acts like a gliding joint when you jut your jaw forward.
To add to the complexity of the TMJ, it is the only joint in the body wherein its motion directly affects the other joint on the other side of the head.
The TMJ also is home to one of the body's fastest reflexes. The reflex causes the mouth to open quickly in the event the teeth encounter an unexpected hard object that could fracture the teeth. If you doubt this, hide a small pebble in your soup.

What plane of motion does the tmj go through?
The temporomandibular joint (TMJ) primarily moves in two planes of motion: hinge motion for opening and closing the jaw, and sliding motion allowing for side-to-side movements and protrusion/retraction. It is a unique joint that can move in multiple directions to facilitate activities like chewing and speaking.

TMJ is an abbreviation for your jaw joint, just under your ear. TMJ stands for 'temporo-mandibular joint. When people say, "I have TMJ", they really mean that they have a TMJ disorder which can range from the TMJ popping when the mouth is opened or closed all the way to an actual dislocation of the TMJ when the mouth is opened or closed.
What kind of joint is the mandible attached to?
The mandible is attached to the skull at the temporomandibular joint (TMJ). It allows for movements like opening and closing the mouth, chewing, and speaking.

Can tmj cause neck and jaw pain?
Yes, temporomandibular joint (TMJ) disorder can cause neck and jaw pain. Dysfunction in the TMJ can lead to muscle tension and discomfort that may radiate to the neck.

The articulation between the mandible and skull?
The articulation between the mandible (lower jaw) and skull occurs at the temporomandibular joint (TMJ). This joint allows for movements like opening, closing, and side-to-side motion of the jaw. It is a complex joint that can be susceptible to disorders or dysfunction that may cause pain and difficulty with jaw movement.
