cones - ANS-if someone is color-blind, which structure is malfunctioning?
glands, smooth muscle, cardiac muscle - ANS-which reflexes are automatic
If the subject reads at 20/40, then the subject can read at 20 feet what a person with
normal vision can read at 40 feet. This means the subject has poorer than normal
vision. If the subject reads at 20/15, then the subject can read at 20 feet what a person
with normal vision must be at 15 feet to read. This means the subject has better than
normal vision. - ANS-how do you determine someone's eye accuracy
muscles - ANS-which reflexes are somatic
photoreceptors in the eye - ANS-rods for vision in dim light conditions and cones for
vision in bright light conditions.
red-green color blindness. This is more common in males because it is an X-linked trait.
- ANS-what is the most common color vision deficiency
red, blue and green - ANS-Three types of cones exist to detect light at different
wavelengths
the Ishihara color vision test charts - ANS-how to test someone's color vision?
you will use the Snellen eye chart. One partner will stand at the chart indicating which
row of letters the subject should read. Begin at the top and work your way down until the
subject cannot read at least half of the letters correctly. Then, record the results in the
table below. The subject will stand 20 feet away from the Snellen eye chart with any
corrective lenses removed. The subject will cover the left eye with the occluder and read
each line as directed by their partner. Then, the subject will cover the right eye with the
occluder and read each line as directed by their partner. - ANS-how to test visual
