These important ions help regulate homeostasis in our bodies‚ as well as allowing us to move‚ absorb food‚ heal‚ and reproduce. Understanding how these ions work within our bodies will allow us to comprehend the physiology behind muscle contraction‚ nerve signaling and cell signaling. Upon learning about calcium‚ we already briefly know how

causes the membrane potential to change to a less negative value because the K+ ions diffuse out across the membrane. My results went well compared to my prediction because I predicted that the resting membrane potential would become less negative. 3. The extracellular Na+ did not alter the membrane potential in the resting neuron because the Na+ channels were mostly closed. 4. Na+ and K+ both have a relative permeability of 0 voltage outside a resting neuron and a relative negative permeability

(Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? Depolarization has to do with surfaces becoming more negative or positive and reaches a certain point called a threshold. When the threshold is reached‚ an action potential is initiated. 2. What was the threshold voltage in Activity 1? The threshold voltage in Activity 1 was 3.0. 3. What was the effect of increasing the voltage? How does this change correlate to changes in the nerve?

Exercises –Chapter 3 Chapter 3- Physical Layer 1 Q1 • How does a multipoint circuit differ from a point-to-point circuit? • A point-to-point configuration is so named because it goes from one point to another (e.g.‚ one computer to another computer). These circuits sometimes are called dedicated circuits because they are dedicated to the use of these two computers. • In a multipoint configuration (also called a shared circuit)‚ many computers are connected on the same circuit.
