Transcript of Write a short paragraph describing the process and purpose of myelination. Explain how myelination...
Write a short paragraph describingthe process and purposeof myelination. Explain howmyelination changes duringdevelopment & how it relates tolearning.
Objective #2 = Diagram and contrast the principle divisions of the Nervous System
USE these notes to fill in this concept map
Objective #1 = describe the functions of the nervous system
DRAW a picture to Illustrate the 3 functions of the nervous system
Objective #3 = Draw, labelAnd describe the functionsOf each part of a neuron
Create a model of a neuronDraw your model and label the Dendrites, Cell Body, Axon,Myelin sheath, and Nodes*give the function of each part In exactly 2 words.
Define and describeResting Membrane potential
Explain what causesResting Membrane Potential (be specific)
on your sweat page: analogy- what is resting membrane potential like?
Take NOTES from your textbook:
membrane potential is
Resting membrane potential is
resting membrane potential is caused by
Resting Membrane Potential
resting membrane potential is like_______
Outside Axon
Inside Axon
How can we use the NERDs to modelResting Membrane Potentialon our candy neurons?
(negative)
(positive)
= negative ions
= positive ions
The membrane on our candy neuron has a difference inelectrical charge on the inside compared to the outside
This is called ________
Define Action Potential.
Describe the events of the two main phases of action potentials:
describe the ions involved in each phase.
Take NOTES from your textbook:
membrane potential is
Resting membrane potential is
resting membrane potential is caused by
Resting Membrane Potential
Action Potential
Action Potential =
1st Phase =
2nd Phase =
make a flow chart of the phases of an action potential.
How and Where on our candy neuron can wemodel both phases of an action potential?
1st phase (called __________) what happens is ____________2nd phase (called _________) what happens is _____________
How can you model conduction ofthe impulse on your candy neuron?
*Remember to include both phases of the action potential
Explain how and why myelin effectsconduction of the nerve impulse.Add to NOTES:
membrane potential is
Resting membrane potential is
resting membrane potential is caused by
Resting Membrane Potential
Action Potential
Action Potential =
1st Phase =
2nd Phase =
Effects of Myelin
myelin effects the impulse by
myelin effects the impulse because
How has this physiology of nerve impulse conduction been used medically?
Define Resting membrane potential how did/could you model this?Define Depolarization how did/could you model this?Define Repolarization how did/could you model this?Describe Nerve Impulse conduction how did/could you model this?
Contrast Saltatory conduction and Continuous conduction
Write a summary
