Question
Chapter 39, Problem 16TYK
Summary Introduction

To review:

The propagation of action potential through nerve is evolved only once, according to a biologist. Find evidence that either supports or refutes that hypothesis.

Introduction:

The nerve impulse or action potential is generated in the neurons. An action potential is nothing but an electrical impulse. This electrical impulse generates due to the presence of voltage-gated ion channels on the plasma membrane of the neurons and presence of different concentrations of ions (sodium, potassium, calcium) in both sides of the neurons.

Compare and contrast a physical versus a chemical synapse. Where are these synapses found in the body and how do they work in their respective tissues? What are benefits of each in those tissues? Compare and contrast the role of calcium in cardiac versus skeletal muscle.
The venom of some cobras contains a mixture of substances that have a variety of physiological effects. One substance in the venom works by preventing acetylcholine from binding to muscle receptors. Which of the following describes the effect of the venom on the prey of the cobra?   Question 5 options:   Muscle contractions are prevented, causing paralysis.   Muscle contractions occur, but refractory periods would be longer.   Action potentials are continuously generated, causing tetanus.   Weak muscle contractions occur but are limited by ATP production by glycolysis.
