The Nervous System: Unit 6

The Nervous System: Unit 6

Author: Bob Grove
Description:

This lesson is in four parts:

  • The organization of the nervous system, nervous tissue - anatomy
  • Neurons; physiology or the conduction of an action potential
  • The central nervous system
  • The peripheral nervous system
     

Part 1 discusses the organization of the NS; lists the general functions, structural & functional classifications of the NS. Also gives an overview of the central and peripheral NS. as well as the anatomy of neurons and neuroglia. Part 2 looks at the generation of a nerve impulse and its conduction from one neuron to another. Part 3 looks at the Brain and spinal cord or the CNS. Part 4 discusses the PNS, with a concentration on the cranial nerves.

Tutorial

Part 1 - Contents & What You Need to Learn

Part 1 looks at the organization and general functions of the NS, including the following:

List the general functions of the NS
Describe the organization of the NS
List the major parts of the NS
Know the structure and function of neurons
Know the different types of neurons
Know the names and functions of all the neuroglia

Part 1 is composed of my lecture in both video and ppt format. As well as a video from Hank Green and Paul Andersen. Part 1 ends with "Term You Need to Know."

Part 2 - Contents & What You Need to Learn

A quick review of neuron anatomy, followed by an explanation of the generation of an AP. Then a discussion on transmission of the AP at the synapse.

You will find the following in Part 2:

  • Video notes on action potentials
  • Two video clips on Neurons and action potentials

Part 3: The Brain. What Percentage of Your Brain Do You Actually Use?

Two thirds of the population believes a myth that has been propagated for over a century: that we use only 10% of our brains. Hardly! Our neuron-dense brains have evolved to use the least amount of energy while carrying the most information possible -- a feat that requires the entire brain. Richard E. Cytowic debunks this neurological myth (and explains why we aren't so good at multitasking).

Part 3 - The Brain

Identify the functions of the major regions of the brain, understand the basic function of the protection of the CNS, and define certain brain dysfunctions.

Crash Course Anatomy: The Nervous System (Part 3-Central NS)

Hank talks about your central nervous system. In this episode we'll explore how your brain develops and how important location is for each of your brain's many functions.

Part 3 - Internet Research On The Brain

Part 4: The Spinal Cord to the ANS (Includes the Cranial Nerves)

This ppt starts with general info on the spinal cord and nerves. It then looks at the 12 pairs of cranial nerves, as well as the other spinal nerves. This lecture ends with a short discussion on the autonomic NS.
