Description
Topic 2: Information Transmission in the Nervous System 1. The inside of the cell has a resting potential of ____ mV with respect to the outside.  The inside of the cell has a resting potential of about – 70 mV with respect to the outside 2. During resting potential, which ion is found in high concentration inside/outside of the cell?  When the neuron is at rest, potassium (K+) channels are open and keep the neuron at this negative potential 3. Which two ions are responsible for the electrical potential differences?  The electrical potential is caused by an unequal concentration of chemical ions on the inside versus the outside of the cell. Potassium (K+) ions are high on the inside of the cell and sodium (Na+) ions are high on the outside of the cell. An electrical pump within the cell membrane keeps the ions in their appropriate concentrations 4. When neuron is at rest K+ channels are _____  When the neuron is at rest the potassium (K+) channels are open and keep the neuron at this negative potential 5. Dramatic jumps in voltage across the cell membrane are indicative of ______  When a neuron is excited one sees a series of dramatic jumps in voltage across
