Light waves are transmitted across the cornea and enter the eyes through the pupil.
<h3>
FURTHER EXPLANATION</h3>
The eyes and the brain are important in helping people see. Light passes through the eyes and this light gets transformed into electrical signals which are sent to the brain that helps make sense of the object that is seen.
<h3 /><h3>How People See</h3>
- Light is incident on an object (or strikes an object). Some of it get absorbed, some are reflected into a human's eye.
- Light that bounces off the object is transmitted across the cornea, the transparent outer layer of the eye. It refracts the light and makes things look sharp and clear.
- Then the light enters the pupil which is the opening in the eye controlled by the iris or the colored part of the eye. The iris changes the size of the pupil and controls the amount of light that enters the eye. When there is bright light, the pupil becomes smaller. In dim light, the opposite happens and the pupil becomes bigger.
- At the back of the pupil is the lens which again helps focus the light. Its shape changes depending on the distances of the objects that is being looked at.
- The light rays are focused by the lens so that they all converge in the retina which is at the back of the eye. The retina has many specialized cells which are sensitive to light. These cells transform light energy into electrical signals or nerve impulses which form a rough inverted image of the object the person is looking at.
- The electrical signals travel to the brain through the optic nerve. The brain turns the image upright and adds more detail to the vision.

Explanation:
Yes, it is possible to <u>break a bone</u> or pull a muscle if a person slips on a ground or ice. Broken bone is very painful and makes it impossible to walk. You would know for sure if that was the case.
Much more common is to <u>pull a muscle or joint</u>. You would still be able to walk, but it would hurt. In any case you do need to talk to the general practitioner that treats your family or the one available at school.
If you go back to intensive physical exercise, like cheerleading, if the pain does not go away in a few days, you might cause more damage that could turn out very serious.
Finally, <em>arthritis </em>is a term that includes a number of conditions that affect joints. Most of the diseases that are included under the umbrella term of arthritis, have a gradual onset and manifest in older age.

<span>Diamond is an evolutionary biologist, interested in adaptations, and he proceeds to speculate that New Guineans exhibit these heightened-mental-activity traits in response to their environment, which presents them with constant and varied challenges. He gets away with it because (1) this statement is buried inside his main thesis, which is in accord with the fundamental dogma (Western superiority is just an accident of geography), and (2) his superior racial group is non-white, and it's okay to call whites inferior</span>
