Transcript
Nervous System By: Kreg Leytham Neuron • Three types – Sensory – Interneuron's – Motor Neurons Nerves • Myelinated- Faster way to receive a signal • Nonmyelinated- Slowest was to get the signal • Up to 50 times faster Reflex • Basic unit of movement. • Brain and Spinal cord receives signals to move • Sensory signals are spread out through the body to get the signals to the spinal cord up to the brain. Brain/Spinal Cord • Signals travel up the spinal cord to the brain for the action • Example If you touch a hot stove the sensory signals will tell you to take your hand off of it. This happens due to the signals going up the spinal cord to the brain.
