Ear

Infection of external ear and TM disorder may cause joint pain and ear pain respectively. What is the nerve responsible for the cause of pain?

• Facial nerve

• Auriculotemporal nerve

• Chorda tympani

• Glossopharyngeal nerve

• Tympanic nerve

The auditory tube is

• bony

• cartilanginous

• 1/3 bony and 2/3 cartilaginous

• 2/3 bony and 1/3 cartilaginous

• half bony and half cartilanginous

What are the two muscles that accompany the auditory tube?

• Tensor palati

• Tensor tympani

• Levator palati

• Stapedius

• Stylopharyngeus

Children middle ear is more prone to infection because the auditory tube is

• more horizontal

• less horizontal

• longer and wider

• shorter and narrower

• shorter and wider

In the petrous part of the temporal bone, CN 7,8 runs between

• cochlea and vestibule

• cochlea and semicircular canals

• vestibule and semicircular canals

• carotid canal and auditory tube

• carotid canal and mastoid antrum

The facial nerve from brainstem contains fibers to what ganglia?

• Geniculate

• Otic

• Submandibular

• Pterygopalatine

• Trigeminal

Poor drainage allows keratinizing epithelium to collect in the Prussak's space, which is bounded by

• superior ligament of malleus

• lateral ligament of malleus

• tendon of tensor tympani muscle

• neck of malleus

• lateral process of malleus

The epitympanic recess communicates with the mastoid antrum via

• auditory tube

• aditus

• promotory

• round window

• oval window

Which muscle can contract to open up the auditory tube and pulls the soft palate laterally?

• Tensor tympani

• Tensor palati

• Levator palati

• Stapedius

• Stylopharyngeus

Which muscles can contract as a reflex in response to loud sounds to prevent damage to the tympanic membrane, oval window and inner ear?

• Tensor tympani

• Tensor palati

• Levator palati

• Stapedius

• Stylopharyngeus
