PPT-The Action Potential & Impulse/Signal Propagation

Learning Objective Be able to describe what a synapse is Be able to describe how an action potential causes the activation of synapses Be able to explain how signals cross the synapse A synapse is the point where neurons connect together. 2nd. practice. Medical Informatics. Biomedical Signal Processing. TAMUS, Zoltán Ádám. zoltanadam_tamus@yahoo.com. Examples of Biomedical Signals. Action potential. Electroneurogram (ENG). Electromyogram (EMG). Learning Objectives. To understand what factors affect the speed of conductance of an action potential.. To understand what the ‘refractory period’ is.. To understand what the role of the refractory period is in separating one impulse from the next.. Learning Objectives. To understand how an action potential is propagated along an axon.. To understand the difference between the propagation of action potentials in . myelinated . and . unmyelinated. and . Resting Membrane Potential. Part 2. . . Action potential. Action Potential . An . action potential. can be thought of as the “firing” of the neuron.. Action potentials will . propagate . down the length of a neuron’s axon. Action Potential. The nature of Nerve Impulse. Nerve impulses are caused by the movement of electrically charged ions. . **sodium, potassium**. These messages are caused by a potential or a difference between the inside and outside of the membrane of the neuron . What you need to know:. Three Basic Functions. Functional Organization. Neuron Structure. Reflex Arcs. Nerve Impulse physiology. Brain Structure/Function. Basic Functions. of the. Nervous System. Membrane Potential . = difference in electrical charges between inside & outside of neuron. http://highered.mheducation.com/sites/0072495855/student_view0/chapter14/animation__the_nerve_impulse.html. To understand what a . resting potential . is.. To understand how a . resting potential . is established in a neurone.. To understand what an . action potential . is..
