FC: By Chenoa Robertson period 5 Mr. Stephen | The Nervous System
1: I am going to talk about the nervous system and what happens when you damage your brain. In this book I am going to discuss the major parts of the nervous system. Including the Cerebrum,Cerebellum, Medulla Oblongata, Neurons, and the Spinal Cord.
2: Cerebrum is Latin for Brain. The Cerebrum is just the largest part of the brain as a whole. It has six layers of neurons which sit on top of a collection of white matter pathways.
3: It includes about 10 billion neurons, with about 50 trillion synapses. The Cerebrum contains many different parts. It has ridges because it is folded to fit information inside it. It is also divided into two halves called hemispheres. The dividing point is a deep grove called the longitudal cerebral fissure. The different sides of the cerebrum do different things for the opposite sides of the body. The right side of the cerebrum controls things such as imagination and 3-D forms. The other side of the brain, the left side, controls numbering skills, posture, and reasoning.
4: The cerebellum is the part of the brain where the high level functions take place. The cerebellum controls posture, balance, and coordination. It is divided into two different lobes which are connected by white fibers. Also in the cerebellum, there is folia, bundled nerve cells. The brain stem is located directly below the cerebellum.
5: The cerebellum is involved in the coordination of voluntary motor movement, balance and equilibrium and muscle tone. It is located just above the brain stem and toward the back of the brain. It is relatively well protected from trauma compared to the frontal and temporal lobes and brain stem.
6: Cerebellar injury results in movements that are slow and uncoordinated. Individuals with cerebellar lesions tend to sway and stagger when walking.
7: The medulla oblongata is the lower part of your brain that is barried deep in your brain.
8: The medulla oblongata is a structure found in the brains of vertebrate animals, including humans. No matter what animal you are you have to have the medulla oblongata to survive. You could even live with just the lower part of your brain.
9: The reason is because it controls your breathing and if you didn't have it you couldn't live. Thats why when you get paralyzed or have a stroke you can still breathe.
11: A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways, but there is one key difference between neurons and other cells. Neurons are specialized to transmit information throughout the body.
12: Each neuron includes: a Cell Body, Dendrites, an Axon, a Nucleus, and Synapses. Most of the neurons are highly branched in order to receive a great deal of information for the body.
13: Sensory neurons carry information from the sensory receptor cells throughout the body to the brain. Motor neurons transmit information from the brain to the muscles of the body. | motor neurons are responsible for communicating information between different neurons in the body.
14: These highly specialized nerve cells are responsible for communicating information in both chemical and electrical forms. There are also several different types of neurons responsible for sight, smell, and touch.
15: Some neurons have short axons, while others can be quite long. Its just like people everyone was made differently in every different size and shape.
17: the definition of spinal cord: The thick, whitish cord of nerve tissue that extends from the medulla oblongata down through the spinal column and from which the spinal nerves branch off to various parts of the body.
18: The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The human spinal cord is protected by the bony spinal column. The spinal column is made up of bones called vertebrae. Although the spinal column is somewhat flexible, some of the vertebrae in the lower parts of the spinal column become fused.
19: The spinal cord contains white and gray matter. Spinal cord: The name given to the series of nerves which travel down the vertebral column and govern most of the functions of the body, such as movement and sensation. The vertebral column is the bony structure made up of vertebra and intervertebral disks whose primary function is to protect the spinal cord.
20: Poisons: You shouldn't drink alcohol, because it targets your brain in places like the cerebellum. causing you to not be able to walk in a straight line.
21: Damages: If you damage one side of your brain the opposite side gets paralyzed. If you get a blood clot it can lead to a stroke.when having a stroke it targets one part of your brain so the other side of your body would become droopy.
