elastic
Superior Retrodiscal Lamina connects TMJ to:
Tympanic plate (on temporal bone)
Inferior Retrodiscal Lamina connects TMJ to:
articular surface of condyle
[Superior head of lateral pterygoid muscle]
Superior anterior attachment connects TMJ to:
connects capsular ligament to temporal (skull)
[Superior head of lateral pterygoid muscle]
Inferior anterior attachment connects TMJ to:
connects capsular ligament to condyle
What does the Capsular Ligament connect?
skull to the condyle/disc
What does the Temporomandibular Ligament connect?
articular tubercle (of temporal bone) and zygomatic process to neck/disc of condyle
What is the function of the Outer Oblique (Temporomandibular Ligament)?
Prevent over rotation….permits translation
What is the function of the Inner horizontal (Temporomandibular Ligament)?
limits posterior movements into retrodiscal tissues
prevents overextension of lateral pterygoid muscle

sphenoid to lingula (of ramus)
What does the Stylomandibular Ligament connect?
styloid process to ramus
What is the function of the sphenomandibular ligament?
no function in limiting mandibular movement
what is the function of the Stylomandibular Ligament?
limits protrusion
