During depression protrusion and retraction. 



Alternate lateral motion. 



A combination of all these movements produces a rotatory 

 movement of the jaw.

 internally it is very thin; it is attached to the meniscus all 

 round.

surface of the neck of the mandible (the part supporting the 

 condyle) . 



A synovia! membrane lines both compartments of the joint, 

 which may be continuous through a perforation in the cartilage. 



Accessory Ligaments : Spheno-mandibular from the spinous 

 process of the great wing of the sphenoid bone to the lingula 

 on the inner surface of the mandible. 



Stylo-Mandibular, from, the tip of the styloid process of the 

 temporal bone to the posterior border of the angle of the 

 mandible.
