FC: CENTRAL NERVOUS SYSTEM jaxson daskalos
1: CEREBRUM The cerebrum is the largest part in the humans brain. It is divided into halves called hemispheres. The cortex, which is part of the cerebrum is the "control board" of the nervous system. Each side of the cerebrum controls the opposite side of the body. One area of the cerebral cortex controls muscles, this area is called the motor area. Lower areas of the cerebrum control speech, hearing, taste, and smell. The sight sensations are located in the back part of the cerebrum. Your cerebrum is very important to your nervous system functions.
2: SPINAL CORD The spinal cord conducts sensory information to the brain. Also, it conducts motor information to the brain. The spinal cord is a "pathway" for sensory messages to travel to or from the brain.m It is protected by a column of bones called vertabrae. If the spinal cord is damaged or injured it can result in reduced motor function and/or paralaysis.
3: Things that Affect the Nervous System ~Spina bifida is a birth defect where the backbone and spinal canal do not close before birth, leaving the spinal cord outside the body. ~Meth is a drug and it is a stimulant on the cns, Even a little bit of this drug can cause irreversable damages on the cns. ~Concussions occur when your brain is shaken so hard it hits your skull and bruises. Multiple concussions can lead to vision problem, memory loss, and impaired balance. Once you get one concussion, your chance to get another one goes up by 400%.
4: CEREBELLUM The cerebellum controls balance and coordination. It is divided into two hemispheres, both of gray and white matter. If the cerebellum is damaged, some movements will be unpredictable and jerky.
5: MEDULLA OBLONGATA The medulla oblongata is the lowest part of the brain. The brain is attached to the spinal cord. It is composed of both white and gray matter, the white is one the outside. The white matter serves as a pathway. The medulla oblongata transfers your nerve messages to your brain.
6: NEURON There are three types of neurons, sensory, motor, and association. The neurons work together to transmit messages throughout the body. Sensory neurons carry the messages through the body and to the brain. Motor neurons transmit information from the brain, to the muscles. Neurons are very critical to your senses.
8: NERVOUS SYSTEM All components of the nervous system work together to relay all of the messages to your brain, muscles, and throughout your body. It is amazing what your central nervous system can do!
