Rod+Cells+-+CCA

=introduction= toc Have you ever in your life wondered what happens inside your eyeball ? well imagine a solar panel sucking in all the Suns light power for uses, is kind of like what the eyeball does where the light touches an object it bounces off into the eye where the rods and cones absorbs it to see. Rods cells do a handful of help to see and so do cones but they have different functions. Also at the same time they help us see correctly. They have some things in common like a nucleus in their cell body, there are also diseases that are severe and could badly affect the way a person sees.

=What are Rod Cells ?= What are rod cells you are asking? well rod cells are photoreceptors, meaning that they are cells in the retina that help us see. Rod cells only work when we are in slightly dark room. Rod cells are the cells that we have more of in our eyeballs. In a human eye ball there are about 120 million of rod cells compared to another cell called cones that only have 6 million in a eyeball. The rods are very sensitive to the bright light and the change of very dark to bright light.

=Rods and Cones Team up=

Have you ever wondered how it is you can see? There's a whole process behind how you can see. It first starts out with the light, the light bounces off a object you are seeing, the light beam then enters through the cornea, the cornea then bends the light rays in a way that the light can enter into the lens, the lens then focus by either making the hole bigger or smaller depending how much light enters, finally the light touches the back of the retina. The rods and cones are also then detecting the color that comes in to give the vision color. If the light that enters is bright light the rod cells won't be working, instead the cones are going to be working detecting the colors. The picture that enters inside is transferred upside down but the brain then puts it right side up.

=Structure of a Rod Cells= The structure of a rod cell is similar to the many cells. They have the nucleus (the boss of the growth and movement. the most important), the mitochondria ( an origin found in most of the cells which get energy and respiratory) cytoplasm, and the cell membrane. They are photoreceptors and they are long and skinny. Their pigment is on the outer side of them. The rod cell is different than a cone. A cone has the same items in the same spots like the mitochondria, and the nucleus, except the cone shape is slightly different by at the top they are shaped down than a rod. And their nucleus is bigger than the rod's nucleus. =Disease of Rod Cells= We all could be born with the rods and cones being good but there are some diseases that could affect the vision that someone has. for example there are diseases like retinitis pigmentosa. retinitis pigmentosa is a disease that is inherited that can cause severe vision problems, affect the vision, and could create blindness. Retinitis pigmentosa is a disease that he's very sensitive to the quick changes of dark to light light to dark. Another diese is the nyctalopia. Nyctalopia ( night blindness ) night blindness is when they can't see in low light. Usually it could be that there isn't enough vitamin A or from birth.

=Color blindness= Color blindness is a severe disease that a person can have. Color blindness affects the way you see certain colors. It's caused by how in the cone a piece of a pigment isn't there completed that causes the trouble of seeing certain colors like the difference of green and red. Also another type of pigment may not be complete like a puzzle piece that is lost can confuse the colors like blue and yellow. A very rare color blindness is achromatopsia. Achromatopsia is when a person completely lost the pigments and can only see shadows of gray. Like if someone lost all of their puzzle pieces and can't find them. =conclusion= So as you can see rod cells are extremely important for someone to have it helps us see where we are suppose to be walking, our homework that we have, and many many other helpful uses and see the world with color, so with each step we take our rods and cones are working hard to help us see as they are truly hard workers in our body by taking the Suns light processing through the lens, focusing in the retina and the rods and cones working fast to detect what has entered and what color the image is all in a fast way. =References= Web Page View live Web page Archive & annotate page || "Your Eyes." //Kids Health//.
