List
The facial muscle contraction
is monitored by receptors in
Tendons (golgi tendon
organs); Muscles (muscle spindles); Other receptors( skin, joint)
The fibers that are capable
of rapid contraction and high tension but fatigue rapidly is the
Type I or phasic fibers.
The type II or tonic functioning fibers handle lower contraction tension and
is resistant to fatigue.
The lateral pterygoid
muscles function to stabilize the tempromandibular joint and is made
predominantly of
Type II or Tonic fibers
The path of opening and
closing of the condyle without involving the translation of condyle is the
Centric relation
In natural dentition
Centric occlusion is
anterior to centric relation by 1 millimeters
The centric relation is
Tooth determined position.
The condyle in the articular fossa determines the centric relation
Basic movements of condyle
include(s)
Hinge movement; Gliding
movement; Translation
In lateral excursion of
mandible, the condyle appears to rotate with a slight lateral shift referred
as
Bennett movement
The maximum lateral shift
is
10-12 millimeters.
Protrusive movement is 8 to 11 millimeters and retrusive movement is 1
millimeter.
The superior head of
lateral pterygoid muscle functions to
Close jaw. The inferior
head functions to open jaw
