Describes how a sodium potassium pump can maintain a voltage gradient across a cell or neuron's membrane. (Make sure to watch the follow-up correction video!)
Shows how electrotonic and action potentials propagate down cells.
Learn from this video how saltatory conduction or how neurons use both electrotonic and action potentials to have signals move quickly while not losing strength.
Learn from this interesting and intricate video how one neuron can stimulate (or inhibit) another neuron at a chemical synapse.
Lesson plan includes materials, procedures, discussion questions, adaptation, vocabulary, evaluations, extensions and links to external web resources. Students will demonstrate their understanding of nerve cells by researching which method of imaging (position emission tomography, magnetic resonance imaging, magnetic source imaging and gene diagnosis) is best for diagnosis.
A list of student-submitted discussion questions for Nerve Impulses.
To increase reading comprehension, activate prior knowledge, develop collaboration and communication with peers, and determine how key vocabulary words relate to one another using Text Scan.
To reinforce and increase concept comprehension, and to analyze similarities and differences between topics using a Two Column Table.
Looks at Alzheimer’s disease as a way to study modern molecular techniques applied to medicine. Covers human biology and cell functions.
This study guide reviews the parts of nervous system (central and peripheral), parts of the brain, parts and types of nerve cells, nerve impulses, synapses and communication between neurons, and sense organs.
This great animation short about action potential includes information about resting potential, depolarization, repolarization, and the return to resting position.
This great animation short about synaptic transmission includes information about the neuron and exercises on the topic.
This great animation helps to explain the manner and process through which neurons communicate.
These flashcards help you study important terms and vocabulary from Nerve Impulses.
