Presentation transcript:

Objective #1 = describe the functions of the nervous system DRAW a picture to Illustrate the 3 functions of the nervous system Objective #2 = Diagram and contrast the principle divisions of the Nervous System USE these notes to fill in this concept map Write a short paragraph describing the process and purpose of myelination. Explain how myelination changes during development & how it relates to learning.

Objective #3 = Draw, label And describe the functions Of each part of a neuron

Create a model of a neuron Draw your model and label the Dendrites, Cell Body, Axon, Myelin sheath, and Nodes *give the function of each part In exactly 2 words.

Take NOTES from your textbook: Define and describe Resting Membrane potential Explain what causes Resting Membrane Potential (be specific) on your sweat page: analogy - what is resting membrane potential like?

Resting Membrane Potential membrane potential is Resting membrane potential is resting membrane potential is caused by resting membrane potential is like_______

Outside Axon (positive) Inside Axon (negative) How can we use the NERDs to model Resting Membrane Potential on our candy neurons?

= positive ions = negative ions The membrane on our candy neuron has a difference in electrical charge on the inside compared to the outside This is called ________

Take NOTES from your textbook: Define Action Potential. Describe the events of the two main phases of action potentials: describe the ions involved in each phase.

Resting Membrane Potential membrane potential is Resting membrane potential is make a flow chart of the phases of an action potential. resting membrane potential is caused by Action Potential Action Potential = 1st Phase = 2nd Phase =

How and Where on our candy neuron can we model both phases of an action potential? 1st phase (called __________) what happens is ____________ 2nd phase (called _________) what happens is _____________

How can you model conduction of the impulse on your candy neuron? *Remember to include both phases of the action potential

Explain how and why myelin effects conduction of the nerve impulse. Add to NOTES:

Resting Membrane Potential membrane potential is Resting membrane potential is resting membrane potential is caused by 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?

Write a summary Define Resting membrane potential how did/could you model this? Define Depolarization Define Repolarization Describe Nerve Impulse conduction Contrast Saltatory conduction and Continuous conduction
