21. Important questions 1-give short account on Tempromandibular joint
Articulation
1. above : the articular tubercle and the mandibular fossa of the temporal bone
2. below : the head (condyloid process) of the mandible
Type: synovial
Enumerate ligament
The lateral temporomandibular ligament,
The sphenomandibular ligament ,
The stylomandibular ligament
Nerve supply: Auriculotemporal and masseteric branches of the mandibular nerve

22. Give short account on lateral ptrygoid muscle
Origin: greater wing of sphenoid and lateral ptrygoid plate
Insertion: neck of the mandible and articular disc
Nerve supply: mandibular nerve
Action: pull neck of mandible forward
All muscles of mastication innervated by mandibular nerve
