The upward and downward movement of tempromandibular joint in lower animals is due to	Interlocking conical form of teeth; Tempromandibular joint morphology; Lack of muscle attachment. Because of all this factors only, the lower animals are able to move their joint in only one plane.
The anatomic alignment of the teeth and their relationship to the rest of masticatory system is the	Occlusion
Tangential loading of masticatory stress results in	Reduced chewing force
The receptors in periodontium mediate tangential chewing force via	Negative feedback mechanism
The receptor threshold for axially directed masticatory forces appears to be_________ as compared to the tangentially directed forces.	Higher. It is because the axially directed force has a positive feedback while tangential forces causes reduced chewing forces.
