#4
What is the role of the iris in the eye?
To focus light onto the retina
To regulate the amount of light entering the eye
To detect visual stimuli
To convert light into electrical signals
#5
Which of the following is not a primary taste sensation?
#6
Which structure of the eye contains the photoreceptor cells?
#7
What is the role of the cochlea in the hearing process?
It amplifies sound waves
It converts sound waves into electrical signals
It contains the hair cells responsible for auditory transduction
It connects the middle ear to the inner ear
#8
Which of the following statements about the olfactory system is true?
Olfactory receptors are located in the nasal cavity
Olfactory receptors are sensitive to only a few odorants
Olfactory signals travel directly to the thalamus before reaching the olfactory cortex
Olfactory adaptation occurs due to the depletion of odorant molecules in the environment
#9
What is the function of the Eustachian tube?
To regulate pressure in the middle ear
To transmit sound vibrations to the inner ear
To protect the inner ear from loud sounds
To amplify sound waves
#10
What is the purpose of the vestibulo-ocular reflex (VOR)?
To stabilize gaze during head movement
To control the size of the pupil in response to light
To adjust the lens for focusing on near or distant objects
To convert sound waves into mechanical vibrations
#11
How does the brain differentiate between different pitches of sound?
By the frequency of the sound wave
By the intensity of the sound wave
By the complexity of the sound wave
By the phase of the sound wave
#12
What is the function of the utricle and saccule in the vestibular system?
To detect rotational movements of the head
To detect linear acceleration and head position with respect to gravity
To amplify sound waves
To protect the inner ear from loud sounds
