Answer:
1 When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photo receptors turn the light into electrical signals.
These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.Focal vision is involved in examining and recognizing objects related with the macular area of the retina whereas peripheral vision is vision resulting in stimulation of the retina outside the macula. An example of peripheral vision would be looking straight ahead while also being able to see on the side by the eye.
Explanation:
2The pituitary gland is enveloped by dura and sits within the sella turcica of the sphenoid bone. The sella turcica is a saddle-shaped depression that surrounds the inferior, anterior, and posterior aspects of the pituitary.When a pituitary tumor pushes the optic chiasm, it causes visual loss in both eyes. In addition to the optic nerve, which brings vision from the eye to the brain, there are also several other nerves near the pituitary gland that travel to the eyes and help them move normally.

Answer: d. autonomic nervous system
Explanation:
The dilation of the pupil occurs due to the radial muscles. This is controlled by the autonomic nervous system. The autonomic nervous system consists of sympathetic and parasympathetic nervous system. The sympathetic nervous system controls the dilation of pupil whereas the parasympathetic nervous system controls the contraction of pupil.
A dilation response generally involves the widening of the pupil that may be caused by the adrenaline and drugs like cocaine, MDMA, amphetamines, hallucinogens and dissociatives.
