  How are graded potentials created, and how are they different from action potentials? 3. Discuss the ion channels that are involved in the generation of an action potential. 4.

• Myelin for action potential propagation.

  494172 Myelin for action potential propagation. Myelin is important for action potential propagation. Multiple sclerosis is an autoimmune disease where the myelin sheath surrounding CNS axons is progressively lost.

• Differences between nodal cells and atrioventricular myocytes.

  The rapid influx allows a more rapid change in membrane potentials of adjacent cells and therefore a more rapid propagation and spread of potential to a greater distance.

• Synaptic Vesicles Discussed

  the arrival of an action potential (nerve impulse) releases its contents into the synaptic cleft after fusing with the axon terminal membrane.

• Free radical reaction

  Initiation b. Propagation c. Substitution d. Termination 2.

• Predict the major organic product of methylpropan-2-ol reacted with H2SO4 and a free radical substitution reaction with CH4 and heat.

  This is a free radical substitution reaction (type of reaction = substitution, mechanism = free radical) and it is an example of a chain reaction (one step leads on to the next).

  Since the salty cytoplasm of an axon is electrically stimulated and the myelin inhibits charge leakage through the membrane, depolarization at one node of Ranvier is enough to raise the voltage at a nearby node to the threshold for action potential initiation

• Compare the Elements Involved in Project Initiation

  The development of the project concept document is not a collection of product/project deliverables, but rather the definition of what is to be done, why it is being done, and what it's potential business value will be.

• Generation of electromagnetic waves

  A mechanical wave involves transfer of mechanical energy (potential and/or kinetic) in a direction (direction of propagation of the wave) without actual transfer of the molecules of the medium.
