"T M
J" stands for Temporo-mandibular-joint. 'TMD' simply means 'TMJ Disorder'.
The function
of the TMJ is to hold the lower jaw to the head within a certain boundary and guide the jaw movements for
chewing, talking, singing, yawning,
breathing, swallowing, keeps airway open while sleeping, and maintains
the body posture and balance, etc.
All body
joints (TMJ, hip, knee, wrist, ankle, finger etc.) have either hinge
movement or circular movement or a
combination of the two. However, TMJ has
not only hinge and circular movement,
but also has a sliding movement: condyle (head of the jaw bone) moves in and out of the joint socket:
Ginglymoarthroidal (hinge-gliding) joint.
TMJ may be
the most active part in our body next to the heart and lungs. An average
person moves the TM joint 2,000-2,500 times a day/night. If someone
likes to talk excessively or chew gum habitually, it may
move 5,000 times or even 10,000 times
a day.
If this
complex joint receives constant distress beyond the adaptive capacity, the harmony of the system can be
disturbed, TMJ and disc can become displaced, joint and disc can be damaged and
clinical symptoms may be manifested to the jaw, face, head, neck, shoulder,
back, and to the whole body through the musculo-skeletal-nervous system.
The TMJ is
one of the most complex joints in the body. It is composed of a large group of
delicate small muscles, nerves, blood vessels, ligaments, tendons, cartilage, disc, synovial fluid, retro-discal
tissue and each part work in harmony with other parts like a “ Symphony
Orchestra”.
