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.

Greg was diagnosed with Type 2 diabetes as a result of his high blood sugar and insulin resistance.
<h3>
What is Type 2 diabetes?</h3>
It is a condition that affects the way the body processes blood sugar (glucose). With type 2 diabetes, the body either doesn't produce enough insulin, or it resists insulin.
Exercise helps counter the effects of type 2 diabetes in several ways. It increases insulin sensitivity, which helps the cells use any available insulin to take up glucose from the blood. Also, when muscle cells contract during exercise, they are able to take in glucose even when insulin is unavailable.
