*-is a landmark used for the inferior alveolar nerve block which anesthetizes the mandibular teeth

*- if not penetrated during the injection, it may prevent anesthesia

76
Q

what are the two basic movements of the TMJ

A

1.Gliding
- Allows the jaw to protrude (go forward) and retract (go backward)
- Aids in depression of the mandible (opening) and elevation of the mandible (closing)
- Aids in lateral movements
- occurs between disc and articular eminence in upper synovial cavity

2.Rotating-
- Aids opening and closing (depression&protrusion/elevation&retraction)
- Aids in lateral movements
- (chewing)
- occurs between disc and condyle in lower synovial cavity

77
Q

what muscles are responsible for protrusion and retraction in terms of “gliding”

Protrusion- bilateral contraction of lateral pterygoids

Retraction- bilateral posterior portions of the temporalis muscles

78
Q

A
  • opening, closing, and lateral movements
  • opening: depression and protrusion
  • closing: elevation and retraction
79
Q
