Inner ear neuroanatomy

Which part of the inner ear is primarily responsible for detecting head motion and acceleration?

• Cochlea

• Semicircular canals

• Tympanic membrane

• Organ of corti

Which part of the vestibular system are responsible for detecting linear acceleration and head position with respect to gravity?

• Utricle

• Saccule

• Both of the above

• None of the above

The utricle and saccule are components of which structure in the inner ear?

• Cochlea

• Semicircular canals

• Round window

• Vestibule

Which cranial nerve is primarily associated with transmitting vestibular information to the brain?

• CN5

• CN6

• CN7

• CN8

The vestibulo-ocular reflex (VOR) is responsible for:

• Maintaining balance while standing

• Controlling eye movements to stabilize gaze during head movement

• Transducing sound vibrations into electrical signals

• Detecting changes in air pressure

Which part of the vestibular system is particularly important for detecting rotational movements in the horizontal plane?

• Utricle

• Saccule

• Lateral semicircular canals

• Anterior semicircular canals

The cochlea is responsible for

• Detecting head movements

• Converting sound vibrations into electrical signals

• Maintaining balance

• Fixating gaze

The organ of Corti is located within which part of the cochlear?

• Scala vestibuli

• Scala tympani

• Scala media

• None of the above

Sound waves enter the ear canal and cause the __________ to vibrate

• Vestibule

• Round window

• Tympanic membrane

• Cochlea

The primary auditory cortex is located in which lobe of the brain?

• Frontal lobe

• Parietal lobe

• Temporal lobe

• Occipital lobe
