Schoolhouse Rock Video!!!! About the nervous System!!!
The nervous system receives information about what is happening both inside and outside your body. It also directs the way in which your body responds to this information. In addition, your nervous system helps maintain homeostasis!=

Your brain and your spinal cord are the major parts of the central nervous system. The brain is located in the skull, it controls the functions in the body. The spinal cord is a thick column of nervous tissue the links the brain to most of the nerves in your body.

Your nervous system had two divisions that work together. The two divisions are the central and peripheral nervous systems. The brain and spinal cord are apart of the central nervous system. The peripheral nervous system includes all of the nerves locates OUTSIDE of the central nervous system. The central nervous system is the control center of the body. The peripheral nervous system consists of a network of nerves that branch out and connect the central to the rest of the body.

The three types of neurons: There are sensory neurons which pick up stimuli from the internal and external environment and converts each stimulus into a nerve impulse. The second kind of neurons are interneurons. An interneuron is a neuron that carries nerve impulses from one neuron to another. The third kind is a motor neuron. Motor neurons send impulses to a muscle or gland. The muscle or gland react in a response. Neuron_Ans.jpg nervous-system.jpg Screen_shot_2011-04-04_at_12.35.28_Abbie♡.png
