Question

6. Which of the following statements about the pupillary light reflex is NOT correct? Axons from the Edinger-Westphal nucleus are part of the optic nerve that terminates on the neurons in the ciliary ganglion The optic nerve from both eyes project to the pretectum Pretectum neurons project to the Edinger-Westphal nucleus The neurons from the ciliary ganglion innervate the constrictor muscle in the iris 7. Which of the following statements about the primary visual pathway is NOT correct? The left lateral geniculate nucleus receives axonal projections from 40% of the right optic nerve and 60% of the left optic nerve P-cells transmit spatial information: visual acuity (shape, size) and colour (maybe red, orange, yellow, green) M-cells transmit temporal information: aspects of motion such as location, speed and direction The lateral geniculate nucleus receives input from both eyes, but optic tract axons terminate in separate layers.
