The human body is living proof that evolution could never in any sense take place. We are a testimony against evolution. We are an example of why it is impossible for the world to be an aftermath of complete disorder. How? Well for the next few minutes I`m going to tell you about an important feature of our incredible, God given, bodies. This feature that I am referring to would be the nervous system.
The nervous system is composed of two main organs, the brain and the spinal cord. Even though it has only two organs, the effects run all throughout your body from your head to your toes. This system, which is very useful in protecting us, can be attacked by multiple diseases which could shut down the hole system. Two of these diseases I will discuss in a moment.
Ladies and gentlemen, boys and girls may I introduce to you the human brain! Weighing about three pounds, it is composed of neurons that are connected to one another by vast networks of association neurons that all link to each other. Did you know that the adult brain holds 100 billion neurons? That’s right 100 billion neurons in this three pound brain! I bet you didn’t know that to manufacture all the ATP needed, your brain needs a constant supply of oxygen and glucose. The brain takes up 20% of all your body`s blood supply to receive this oxygen and glucose! After all this, I hope you can see just how amazing the brain truly is.
The brain has many interesting features about it. On the exterior part of the brain are gyri, the mountains, and sulci, the valleys. There is also a cerebrum and a cerebellum. The cerebrum is the biggest part of the brain and completes the more complex brain functions. The cerebellum controls the i...

Because of Parkinson`s disease, your lifestyle will change slightly. You will be forced to eat food that has lots of fiber in it and you must drink lots of water to reduce constipation. You will also want to keep walking so that you can keep your muscles strong, but you must walk carefully so that you don’t hurt yourself. The body as a whole is amazing, and when you study just one aspect, it floors you to think that God would care so much about us, to put all His power and creativity into making us. Looking at even just a brief overview of one part of your body proves that there is no way that we could be made out of an explosion. We needed and still need an intelligent God to form us and keep us alive.
I did find it interesting how the individual neurons receive messages as to how a computer does. “An individual neuron may receive information from thousands of other neurons.” From my basic study of how a computer functions this is not the case in them. Computers receive information from various sources but nowhere near thousands, and when the message is relayed it is immediately carried out. However in neurons this is not the case as stated by Chudler. “Remember, the receiving neuron may be getting thousands of small signals at many synapses. Only when the total signal from all of these synapses exceeds a certain level will a large signal (an action “potential”) be generated and the message continued.” This is much different from a computer, for every keystroke and action is immediately taken, where as in our brain it takes thousands of synapses milliseconds to make me type. The speed and accuracy of my typing is affected by the ability of my neurons to send action potentials.
The braine has three layers into exterior of the entire brain.1-meninges, 2-dura mater and 3-arachnoid layer and the pia mater.
The cerebrum has a gyrus structure, which means that that brain tissue is arranged in a convoluted manner. This gyrus structure allows for more brain surface area, which means brain tissue is present to perform
The number of synaptic inputs recieved by each nerve cell in our (human) nervous system varies from 1-100,000! This wide range reflects the fundamental purpose of nerve cells, to integrate info from other neurons.
The brain, like the rest of the nervous system, is composed by and large of neuralgia (glial cells), nerve cells (neurons), that are immersed in a constant flow of cerebrospinal fluid. The glial cells far outnumber the neurons, but have no axons or synapses, and therefore do not play a part in the electrical activity of the brain. They are simpler looking, much smaller, and have lower metabolic rates than neurons.
The nervous system is a network of cells that take messages from the brain and spinal cord to other parts of the body. The nervous system is made up of the Central Nervous System and the Peripheral Nervous System. The Central Nervous System has two main parts; the brain and the spinal cord. While the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included within it.
The brain has many different parts to it which help one function through daily life; parts such as the cerebrum which controls voluntary movement and regulates functions such as thinking, speaking and the ability to recall information. The cerebellum controls the balance and coordination and finally the brain stem, which consists of the medulla oblongata and the spinal cord which controls all involuntary functions such as breathing, heart rate and blood pressure. The brain stem is also able to carry out these actions even when someone is asleep. To fully understand how crucial the brain is to survival one must understand the functions of the brain stem.
The largest part of our brain is the cerebrum, which is basically what most people imagine when we
The brain is one of the most interesting yet the most complex part of the body. Since no one can really see what’s inside, it’s a big question for most people on how it works. The brain is made up of more than 100 billion neurons that communicate through the synapse. It controls all the function of the body, receive and interprets information and process thoughts and emotions (Hines, 2016). It is one of the most important part of the body. How we remember, how we think, do and etc. is made possible because of the brain. The brain is divided into three main parts: cerebellum, cerebrum and brainstem. Each part has its own specialised area on the body in order to function well (Hines, 2016).
...ke structure that connects the cerebrum with the spinal cord. The brain stem controls the reflexes and automatic functions, such as heart rate, blood pressure, limbs movement and visceral functions like digestion and urination (Striedter 529). Well these three divisions are very important to the human brain and body, these are the divisions that allow us to be able to move, speak, and about any other action you could think of.
The brain is an incredible part of our body and it controls everything from body coordination, thinking processes, and regulating body functions. The brain has enough energy to power a 25watt bulb. Now that’s power! The brain is composed of the cerebrum (and its lobes), the thalamus, hypothalamus, brainstem and cerebellum. The cerebrum consists of the; frontal lobe, parietal lobe, temporal lobe, and the occipital lobe. It’s the largest part of the brain and accumulates 85 percent of the weight. (1) Each part of the brain has its own specific and unique functions. Scientists have and still are studying to unlock the mysteries and full potentially of the human brain.
This paper involves how the brain and neurons works. The target is to display the brain and neurons behavior by sending signals. The nervous system that sends it like a text message. This becomes clear on how we exam in the brain. The techniques show how the brain create in order for the nerves about 100 billion cells. Neurons in the brain may be the only fractions of an inch in length. How powerful the brain could be while controlling everything around in. When it’s sending it signals to different places, and the neurons have three types: afferent neurons, efferent neurons, and the interneurons. In humans we see the old part of emotions which we create memories plus our brain controls heart beating, and breathing. The cortex helps us do outside of the brain touch, feel, smell, and see. It’s also our human thinking cap which we plan our day or when we have to do something that particular day. Our neurons are like pin head. It’s important that we know how our brain and neurons play a big part in our body. There the one’s that control our motions, the way we see things. Each neuron has a job to communicate with other neurons by the brain working network among each cell. Neurons are almost like a forest where they sending chemical signals. Neurons link up but they don’t actually touch each other. The synapses separates there branches. They released 50 different neurons.

The area at the front of the brain is the largest. Most of it is known as the cerebrum. It controls all of the movements that you have to think about, thought and memory.
