Nervous System Function

Nervous System. The nervous system is broken down into two major parts:

Two functions of the nervous system a. Somatic, voluntary movement b. autonomic, involuntary movement.

As a result of the coordinated structures and functions of organ systems, the internal environment of the human body remains relatively stable (Homeostatic)

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: Describe the job of the Neuron cell anatomy Dendrites, Myelin Sheath of the Schwann cell, Axon terminals, The Axon at the nodes of Ranvier Describe the sequence of events that lead to an action potential and a depolarization of the neuron. Describe the passage of neurotransmitter across a synaptic cleft. 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. http://webspace.ship.edu/cgboer/theneuron.html

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 A nice description how a nerve works. Watch this first then watch the next video to learn more about the action potential https://www.youtube.com/watch?v=6qS83wD29PY&index=1&list=PLNZqyJnsvdMqFNFyHvMFrFnlXLosnwwB_
