Nervous System

Wikipedia
Function:
The nervous system's main function is controlling everything you do, whether voluntary or involuntary.

Organs:
Brain- The brain is the control center for your entire body. It controls things such as memory, planning, and other voluntary actions. It can also control things like your heart rate and digestion.
Spinal Cord- The spinal cord carries signals and information from the brain to other parts of your body.
Nerves-Nerves allow signal and information to travel from the brain to the spinal cord and all around the body.

Interactions:
The nervous system is like the circulatory system, they both interact with every other system. Some can be quite obvious like the muscular system. When you want to move your brain transmits signals to create movement. The nervous system is also in charge of involuntary actions like your heart beating, the breaking down of food and more. The digestive system works with your nervous system when the food is broken down and absorbed, but it does connect when you eat and dispose of waste. In addition, your thoughts control when you pee which is how is connects to the urinary system. The nervous system has connections with every part of the body.

 Analogy:

The nervous system is like sending mail from one place to another. To begin with you write a letter, representing your brain figuring out what the function is. Putting it in the mailbox and how the mailman takes it all the way to where it needs to go is like the information traveling down the spinal cord. Once it reaches the person who it was supposed to go to the function is carried out by whatever organ or muscle had the job. What this analogy really shows is that it all starts with the brain and that is a very true statement. Sending mail is a great example and way to remember the nervous systems function.

 Structure and Function (Brain):
The brain is made up of many complex components which each have their own functions. One part of the brain is the cerebum. It is made up of four lobes that are controlling reasoning, movement, visual processing, memory and more. The cerebum is wrinkled which helps it complete its functions in a faster manner. How you ask? Well, this allows it to enlarge the surface area and the neurons. This part of the brain is split right through the middle having the left and right hemisphere of the brain. Nerve cells are in some parts of the cerebum and they carry signals that travel to the brain and other parts of the body. The cerebellum is a lot like the cerebum because both are divided in half. It is smaller than the cerebum, in charge of coordination, posture, balance, and it is much older. The lymbic system is the emotional part of your brain and is also much older than the cerebum. Lastly, the brain stem is the key for vital things such as heart beat and breathing. This must be why it is under everything connecting it to the rest of the body.

Cladograms, cladograms, cladograms 10/22/17

Image: Pierre Kleinhouse Summary:  When we think of evolution we see monkeys magically turning into humans, but what is missing from that picture is the portion below it that makes it a cladogram. What is a cladogram? A cladogram is a diagram that shows the common characteristics of certain animals, as well as how closely related they may be. The top of the cladogram includes the organisms name and sometimes a picture. On the side of the cladogram, you will usually see different characteristics. Since a cladogram is drawn at a downward angle, the characteristic applies to everything above that point on the diagram. As you go up the cladogram, the animal at the top has all the characteristics listed throughout the cladogram. Along with this, the points in which two animals meet is not when they evolved from one another, but their common ancestor. Lastly, the diagonal line of a cladogram represents time.

Image: www.flickr.com Summary: Throughout this week, the main topic of discussion was food waste and food systems. To understand the food system and how it works, we went through the system of apples and how they can be wasted in each step. The apples are produced and they can be wasted when they are eaten by insects. Due to this, they can't sell, so the farmers throw the apples away. Next, the apples are harvested. If apples have fallen on the ground or are not up to standard the farmers throw them away, even though they are perfectly fine. After that, the apples are washed and waxed to look appealing to customers. During this step, apples are wasted if the they are ruined while waxing. Some apples are then processed into different food items, such as pie filling, apple sauce and more. If people mess up during this conversion, the apple product gets thrown away. Then, the apples are packaged.If packaged incorrectly, the apples get thrown away. After this step, the apples ge...
