Transcript Nerve Cell Signaling - Mr. Moore`s Web Page

Nerve Cell Signaling
State Standard
• 4.4 Explain how the nervous system (brain,
spinal cord, sensory neurons, motor neurons)
mediates communication among different
parts of the body and mediates the body’s
interactions with the environment.
Standards Unpacked
Write these objectives in your notebook
• Students will be able to:
1. Describe the job of the Neuron cell anatomy
1. Dendrites, Myelin Sheath of the Schwann cell, Axon
terminals, The Axon at the nodes of Ranvier
2. Describe the sequence of events that lead to an
action potential and a depolarization of the
neuron.
3. Describe the passage of neurotransmitter across
a synaptic cleft.
4. Identify what a motor neuron and sensory
neurons do and where they are located in the
body.
Objective 1
• Use this web site to answer objective #1.
Write the cell part and its function in your
notebook.

Neuron Anatomy
How does a nerve work
• Watch each of the videos that follow. Use the
videos to describe the process of depolarization.
Try to do it in a series of steps. You can also use
other web sites to help you in this process. You
might want to use the picture on slide 9 to help
you describe the process. Write the process in
your notebook.
A nice description how a nerve works. Watch this first then
watch the next video to learn more about the action potential

Notes for synaptic cleft signaling
• Watch the videos and describe the process of
neurotransmitter movement across the
synaptic cleft. Try to describe it in steps. Use
the picture Mr. Moore provides you to help
you with your description.
