Vision Flashcards
Which is not of the vertical layers of the retina?
- Bipolar cells
- Ganglion cells
- Amacrine cells
- Photoreceptor cells
Amacrine cells
Which photoreceptor can distinguish different colors?
Cones
How many cones does each retina have?
6 million
Which summary of visual pathway is correct?
Retina - Optic chiasm - LGN - primary visual cortex
What does not apply to rods?
Detailed colour vision
The axon of these cells form the optic nerve:
Retinal ganglion cells
Which statement about blind spot is correct?
Blind spots are where optic nerves leave the retina
Axons extending from the nasal part of the retina project to the … side of the brain, while axons from the remainder of the retina project to the … part of the brain.
Opposite (contralateral), same side (ipsilateral)
The first structure which the majority of retinal ganglion cells project to in the brain is the:
Lateral geniculate nucleus
What is the correct visual pathway before the optic nerve?
Light reaches rods & cones, bipolar cells than ganglion cells
Which part of the eye controls the amount of light entering?
The pupil
Information from rods will go through low convergence to retinal ganglion cells, T/F
False
Cones provide high detailed vision T/F
True
Rods respond better in dim lights, T/F
True
A characteristic of rods: work well in bright light, T/F
False
