The human eye can focus objects at different distances by adjusting the focal length of the eye lens . This is due to
Presbyopia
Accommodation
Near-sightedness
Far-sightedness
Rod cells of retina corresponds to
Light sensitivity
Colour sensitivity
Size sensitivity
All of these
What turns the sound waves into neural signals ?
movement of malleus against the cohlear nerve
The movement of the liquid against the clia
Movement of the cilia as fluid waves bend the basilar membrane
Movement of the cilia due to gravitational forces
Malleus
What happens in the tympanic membrane
?
Sound waves are converted to vibrations.
Sound waves make the tiny hairs in your ear move
Carries the message to the brain
What does the fluid inside your ears do when displaced?
Vibrates the skin in your ear
Sends sound waves to the brain
Displaces the hair cells.
Stimulates the hair cells to send an impulse
The diagram above represents
Cupula
Crista Ampullaris
Utricle
Saccule
The diagram above represents
Cupula
Ampulla
Macula
Which of these anatomical sequences is correct?
tympanum-incus-malleus-stapes-oval window-round window
tympanum-incus-malleus-stapes-round window-oval window
tympanum-malleus-incus-stapes-round window-oval window
tympanum-malleus-incus-stapes-oval window-round window
Which of the following descriptions best matches the term basilar membrane?
supports the olfactory organ
moves up and down when the stapes moves back and forth
covers over the oval window
tiny duct necessary for the static sense of equilibrium
transmits movement of the tympanic membrane to the inner ear
Low frequency sounds stimulate hair cells on which part of the basilar membrane?
the distal end
the middle region
the entire membrane
area close to the oval window
The following is a list of the steps that occur in the production of an auditory sensation.
1. The pressure wave distorts the basilar membrane on its way to the round window.
2. Movement of the tympanic membrane causes displacement of the malleus.
3. Displacement of the stereocilia stimulates sensory neurons of the cochlear nerve.
4. Movement of the malleus causes movement of the incus and stapes.
5. Distortion of the basilar membrane forces the hair cells of the organ of Corti toward or away from the tectorial membrane.
6. Movement of the oval window establishes pressure waves in the perilymph of the vestibular duct.
The proper sequence for these steps is
2, 4, 6, 1, 5, 3
2, 1, 4, 6, 5, 3.
2, 4, 6, 3, 5, 1
2, 4, 1, 6, 5, 3.
2, 5, 4, 6, 1, 3
The ability to know where your head is in relation to space around you when your head is NOT moving is called
static equilibrium
dynamic equilibrium
The position of the head with respect to gravity is determined by the
shift in fluid in the semicircular canals.
movements of otoliths in response to gravity.
movements of perilymph in the vestibular chamber.
impulses transmitted from the macula of the semicircular canals.
Otoliths
amplify hearing.
are part of the ampulla.
are found in the semicircular canals.
are embedded in a gelatinous mass.

True or false?
In rod cells, when a photon of light (the smallest unit of light) hits a molecule of rhodopsin, rhodopsin breaks down into trans-retinal and opsin.
This is known as bleaching.
