Introduction Millions of sensory neurons are delivering information to the CNS all the time Millions of motor neurons are causing the body to respond in a variety of ways Sensory and motor neurons travel by different tracts within the spinal cord.

Heritage College . What are Mirror Neurons?. Mirror neurons are cells that fire when a monkey (or person?) performs an action or when it views another animal performing that same action. What are Mirror Neurons?. Located in conjunction with a frontoparietal action planning network:. Sensory systems receive information from the environment via specialized receptors in the periphery and transmit this information through a series of neurons and synaptic relays to the CNS. . Sensory . The Nervous System. Eating?. Playing a musical . i. nstrument?. Reading a book?. Running?. Sleeping?. It’s a trick question, because ALL of these activities involve your nervous system.. In fact, your nervous system controls almost everything you do. Pain happens only in your head.. Anyone can be hypnotized.. Nerves don’t actually touch each other.. Not feeling pain is a good thing.. Most people can get along just fine with out senses.. You can control your nervous system.. The Nervous System: Communication. Neurons are masses of nerve cells that transmit information. Three main components:. (1) Cell Body – contains the nucleus and two extensions. (2) Dendrites – shorter, more numerous, receive information. The sensation and input we receive by using one or all of our senses. A treatment modality commonly used for individuals with moderate to severe disabilities or health conditions. Offered to all age groups and in a variety of settings. The sensation and input we receive by using one or all of our senses.
