Melanin Magic and Perfect Paragraphs

Rayyon, Age 9

My essay read all about stuff you probably do not know like melanin. In this essay you will read about melanin and other things. I'm gonna tell you about the substantia nigra, melanin in the eye , and melanin in animals. Melanin in animals will tell you about some animals that have melanin. It will also tell you how the melanin helps the animals. Melanin in the eye will tell you where melanin is in the eye. It will also tell you what it does. The substantia nigra will tell you about what it is. It will also tell you what it does to help your brain.The reason I wrote this paragraph is to tell you stuff you probably didn't know. 

The substantia nigra helps your brain. If there was no melanin in the substantia nigra you will get parkinson disease. Parkinson disease can kill you. This is why melanin is important. You can cure it by eating fruits and veggies. The substantia nigra is very helpful. The substantia nigra is a big help to your brain. This is what the substantia nigra does. 

These are the 3 places that have melanin in the eye. There is melanin in the retina. The retina absorbs the light that the retina cells don't want. There is melanin in the choroid . The choroid reflects light the eye does not want. There is melanin in the iris. The iris reflects light it does not want. These are the 3 places that have melanin in the eye. 

There is melanin in animals. There is melanin in chameleons. The melanin helps it blend in. There is melanin in bats. The melanin in bats helps it hear better.There is melanin in roaches. The melanin gives it a hard exoskeleton. These are the melanin in animals. 

Did you know melanin was so amazing. I bet you did not. Now you can tell people about melanin. What was your favorite part? Was it melanin in animals? Or melanin in the eye? Or was it the substantiation nigra? Now you know about melanin.

Melanocytes are cells that make melanin. Melanin is a substance it is made by melanocytes and it is increased by the sun. We also have an integumentary system that is made up of skin. We all have three layers of skin. You can say the melanin eats the sun but not exactly like when you tan the melanin absorbs the sun. If there's a lot of sunlight melanocytes make a lot of melanin but less sun means less melanin.


There is also a disease that you get in your skin it is called carbuncles. Most carbuncles are caused by the bacteria Staphylococcus aureus (S aureus). A carbuncle is a cluster of several skin boils (furuncles).The infected mass is filled with fluid, pus, and dead tissue. Fluid may drain out of the carbuncle, but sometimes the mass is so deep that it cannot drain on its own.The bacteria that cause this condition spread easily. So, family members may develop carbuncles at the same time. Often, the cause of a carbuncle cannot be determined.


The last thing I want to talk about are blisters. A blister is a small pocket of fluid in the upper skin layers and is a common response to injury or friction. The feet are particularly prone to blisters. Blisters rarely need medical attention unless they are severe, recurrent, caused by burns or are due to an underlying. Gently cleansing the area with soap and water and covering the blister with a bandage may help heal it. It's best to avoid bursting the blister as the skin covering it may provide a natural barrier to infection. 

Now you know about  Melanocytes,carbuncle, and blisters.There are many kinds of skin diseases and illness so you can study all kinds of diseases. You can find out cures and cons so that if you need to do a essay you will know what to do.

You have to know about melanin. If you read this you will learn about melanin. You will learn about animals with melanin the melanin in the eye and about the substantia nigra.         


The substantia nigra has melanin. The substantia nigra is part of the brain. Next to the pons. we need our substantia nigra. It helps us move. We have melanin in are substantia nigra.

Animals have melanin. Bats have melanin. Bat have melanin in their ears and wings. Cockroaches have melanin. They have it in under there shell. Chameleons have melanin. They have melanin in their skin. Animals got melanin to.

There is melanin in the eye. There is melanin in the retina. The melanin in the retina takes the light that the retina doesn’t want. In the choroid there is melanin. The melanin in the choroid takes the light that bounces around the inside of the eye. There is melanin in the iris. The melanin in the iris takes some of the light before gets to the eye. We got melanin in our eye.


Did you learn something new about melanin or learn what it is? Now if you have a question please look back over the essay to the paragraph you think may answer your question. After you are done with this essay please be careful with your melanin. Thank you for reading bye.

If you want to know about melanin read my essay.You can learn about melanin where is it what it does and more. You can learn about how animals have melanin. Like the Ayam Cemani chicken or the black sheep. We will also learn what melanin does to you. Like how melanin effects your skin color. So i hope you like my essay enjoy.


Some people know that there is  melanin in the eye but do you know where or why we have melanin in the eye? One of the places that have melanin in them is called the retina. The retina is located in the back of the eye and the melanin takes in the light that the retina cells do not want. One of the other parts of the eye is called the choroid. The choroid is located even more back than the retina and takes the light that bounces around the inside of your eye.   One of the last places that have melanin is called the iris.  The iris is located in the front of the eye the melanin in the iris takes some of the light before it gets into the eye.   So now you know about melanin in the eye where it is, what it does, and the three parts that have it.

We have learned lots about melanin in the human body but there is also melanin in the animal body which does some cool stuff.  One of the animals that have melanin  in the body is called the bat.  The bat can use  the melanin in its ear to use a type of navigation called echolocation.  Another animal that has melanin in them is called the chameleon.  The chameleon uses the melanin in its skin called to camouflage.  One of the last animals that I am going to mention is called the cockroach.  The cockroach uses the melanin in its exoskeleton to make it super hard and nearly indestructible.  So as you can see melanin helps the animals a lot. 

We have learned that there is melanin in the eye but did you know that there is melanin in your brain.  There are three parts of your brain that contain melanin.   They are called the pars compacta, locus coeruleus and the substantia nigra. This brain melanin also called neuromelanin is very good for your brain.  It helps you be well coordinated and to think well it also gives your brain that pinkish color. It would not be good at all if you did not have melanin in the brain.  Not only would your brain lose its color or you would not be well coordinated but sometimes you could even catch a disease.  So now you know where the melanin in are brain is and what it does and what would happen if you lost it.

We have learned about the system of the body but did you know that your skin is a system of the body.  Your integumentary system has three layers one at the top one in the middle and one at the bottom. They are called the epidermis dermis and subcutaneous tissue. Your integumentary system also has to other parts sweat gland and a muscle that moves your hair. Your sweat gland is in charge of making sweat and your muscle makes your hair stand up when your cold or scared.  You also have cells called melanocytes are located in the epidermis and the dermis. Melanocytes take in the sun's energy and use it to make melanin if there is not a lot of sunlight you would not be able to make a lot of melanin. So know you know you know more about your skin and why we need a integumentary system.
