Which neurons recognize the "fundamental" vibration in sound?

• Volume-sensitive neurons

• Pitch-sensitive neurons

• Tone-sensitive neurons

• Rhythm-sensitive neurons

What happens to humans who lose the ability to distinguish pitches after a stroke?

• They lose all hearing

• They cannot recognize melodies

• They cannot distinguish pitches

• They lose memory of lyrics

Where are the olfactory organs located?

• In the inner ear

• In the nasal cavity

• On the tongue

• In the eyes

What is the role of olfactory bulbs in the olfactory pathway?

• They produce odorant molecules

• They conduct impulses to the olfactory cortex

• They detect sound waves

• They regulate body temperature

Trace a sensory impulse from a taste receptor to the cerebral cortex.

• Taste receptor → Thalamus → Cerebral cortex

• Taste receptor → Medulla → Cerebral cortex

• Taste receptor → Spinal cord → Cerebral cortex

• Taste receptor → Cerebellum → Cerebral cortex

How do the auditory ossicles affect sound vibrations?

• They decrease the force of vibrations

• They transmit vibrations directly to the brain

• They amplify the force of vibrations

• They block external noise

How do hair cells in the inner ear respond to sound vibrations?

• By producing neurotransmitters.

• By depolarizing and creating action potentials.

• By releasing hormones.

• By contracting and expanding.

What is the range of sound wave frequencies that a young person with normal hearing can detect?

• 20 to 20,000 vibrations per second.

• 2,000 to 3,000 vibrations per second.

• 200 to 2,000 vibrations per second.

• 20 to 2,000 vibrations per second.

What fluid is contained within the cochlear duct?

• Perilymph

• Endolymph

• Cerebrospinal fluid

• Synovial fluid

What is the role of the semicircular canals in dynamic equilibrium?

• They detect sound waves

• They detect motion of the head and aid in balance

• They amplify sound vibrations

• They transmit vibrations to the cochlea
