Document Summary
Our body is not in cartesian coordinates. Because changes in joint angles are the basis for our movements, the brain must transform joint coordinates into cartesian coordinates to move to a point on the real world. Develops as an outpouching from the diencephalon during embryonic development. The outer covering (white)- the sclera is the dura mater that protects the brain. The cornea and (to a lesser extent) the lens refract light rays coming onto the eye (light bending). The points all converge on the retina to create the focused image. Emmetropia= perfect vision: measured by diopeters (refractive power), and it is 42 diopeters here (the diameter of the eye matches the refraction produced by the cornea), diopeters= 1/focal distance (m) Myopia- the eye diameter is too large for corneal refraction, the cornea bends too much light rays, not a sharp point, more of a spread, shortsighted- faraway things are blurry.
