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
