Multiple Choice

What is the role of ligaments?

• To connect muscle to bone

• To protect internal organs

Multiple Choice

What is the function of the attachments of the articular disc to the medial and lateral poles of the mandible?

• To allow the mandible to move freely in all directions

Multiple Choice

What is the function of the superior lamina in relation to the tympanic pad?

• It allows the disc to translate anteriorly

• It connects the disc to the mandibular fossa

• It provides stability to the joint
