  1. The Central Nervous System By: Chase Lewis

  2. The two main parts of the central nervous system are the brain and spinal cord. The brain is the control center. The spinal cord is the main highway. The nerves (neurons) are the signal carriers. Central Nervous System

  3. The brain is the control center of the body. The average adult human brain weighs 3 pounds. The brain contains about 100 billion nerve cells. Your brain is about 2% of your total body weight but uses 20% of your body's energy. The energy used by the brain is enough to light a 25 watt bulb. The Brain

  4. The frontal lobe – This part of the brain is the primary command and control center of your brain. It is responsible for reasoning and problem solving along with judgment and impulses. It can also be involved in motor control and memory. The Parietal Lobe - This part of the brain helps to process pain and touch sensation. It is also involved in cognition. Parts of The Brain

  5. The Temporal Lobe helps to process sound sensation as well as language. It is also involved in emotion, memory and speech. The Occipital Lobe is involved in visual sensation and processing. The part which controls and interprets vision resides there Parts of The Brain

  6. The Pons - It is also involved controlling automatic body functions. The Cerebellum - This part deals primarily with controlling movement. It helps to control posture and balance as well as helping people to learn movement. Parts of The Brain

  7. The cerebrum is the most highly developed part of the human brain. It is here that things like perception, imagination, thought, judgment, and decision occur. Brain Stem: The brainstem is the region of the brain that connects the cerebrum with the spinal cord. Motor and sensory neurons travel through the brainstem allowing for the relay of signals between the brain and the spinal cord. Parts of The Brain

  8. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. A pair of spinal nerves leaves each segment of the spinal cord. The length of the spinal cord is about 45 cm in men and 43 cm in women. The Spinal Cord

  9. Cervical Nerve branches off from the nerves in the spinal cord. The cervical nerves are responsible for relaying messages and ensuring functioning to different body parts. C1-C8 controls the head, diaphragm, upper body muscles, wrist extensors, triceps, and hand. Thoracic spine refers to the upper- and middle-back. T1-T12 controls the chest and abdomen muscles. Thoracic spine is built for stability. This stability plays an important role in holding the body upright and providing protection for the vital organs in the chest. Parts of The Spinal Cord

  10. Lumbar spine has no spinal cord and is made up of a large amount of space for the nerve roots. L1-L5 controls the leg muscles. Sacral nerve is located at the bottom of the spine. S1-S5 control the bladder and bowels. Parts of The Spinal Cord
