FC: Essential componets of bodies system By: Stephen Franco Mr.Stephen period 5
1: The cerebrum is the largest part of the brain. Within this section of the brain the cerebrum is where judgments, perception, decisions, imagination, and thoughts occur in. The cerebrum is the most dominant part of the brain. | The cerebrum can be divided into two halves. The right half of the cerebrum controls the left side and the left half controls your right side. The two halves of the cerebrum linked together by white matter called corpus callosum.
2: The cerebellum helps control voluntary movement, and it is involved with controling coordination. The cerebellum is well more protected thanks to the cerebrum that it lays underneath. The cerebellum has parallel groves called the cerebral cortex which shows that the cerebellum is actually a thin tissue called the cerebellar cortex and is folded like an accordion. | Although the cerebellum is well protected it can still be injured. Signs of injury are: slurred speech, staggering, and abnormal eye movement.
3: The medulla oblongata is the lowest section of the brain stem. It has the duty of making sure that your heart keeps beating, you keep breathing, and other vital functions. | The lower eight cranial nerves connect to the medulla oblogata in a lesser or greater degree. In the medulla oblongata the auditory nerve is a compound nerve made of two the cochlear nerve and the vestibular nerve.
4: Neurons are specialized cells that carry electric messages to parts of the body. The average human brain contains 100 billion neuron cells. Neuron cells can come in different shapes and sizes. A neurons cell body can be as small as four microns to 100 microns wide (one micron equals 1/1000 of a millimeter. | When a neuron carries a message to any part of the body it travels as a electric signal. When it reaches to the end plates since the other end plates aren't touching the signal has to turn into a chemical signal and travels to the other end plates. When received the chemical is turned back into an electric signal, this is called a synapse.
5: The spinal cord is inside and protected by the spine. It only extends to the last thoracic bone. In men the spinal cord is 45 cm long, for women it's 43cm. The spinal cords two main jobs are to transport messages from the brain to the rest of the body and the spinal cord has the ability to do reflexes. | A reflex is a defensive way of your body protecting itself, for example when you touch something really hot you instantly pull your hand back before you even feel it. Because the spinal cord only extends to the last thoracic bone nerves branch out at lumbar and sacral.
6: Your brain is a wonderous organ yet some people have little respect for it. When you drink or smoke or do drugs you can damage your brain, your also posining your body as well. | Some people take drugs because the affect it has on the brain can cause hallucinations and the feeling of being high.
7: Drugs aren't the only concerns, seizures can be deadly. You can get seizures by coming over great stress, injuries, electronics, ans strobe lights. | On December 16, 1997 Japan aired the 38th episode of pokemon, this episode was the first to have the major appearance of the pokemon porygon. Porygon is a pokemon created by humans capable of entering cyberspace. In the episode the main characters sucked into cyberspace in order to rescue a porygon. Pickachu used an electric attack made by strobe lights giving 685 children viewers seizures sending them to the hospitals. Now the episode is banned world wide, and as for porygon and it's evolved forms porygon2 and porygon-z they are not allowed to make major appearances on anime.
