The Nervous System: Unit 6

The Nervous System: Unit 6

Author: Nate Holz

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.

Unit 6 Class Log

  1. Monday (1/9): Guest Speakers Amy and Emily (MCHS graduates 2016) talking about their JC experience. No homework or handouts...
  2. Wednesday (1/11): Notes-"Organization of the Nervous System." 3 handouts: Concept Map, Neuron Label, and a Reading Guide. We also watched a few video clips regarding the NS.
  3. Friday (1/13): Video lecture day! Notes-my 2nd video, this one on action potentials or what generates or is a thought. Just before my note video, we watched a college level 6' video on neuron structure (see it below.) After my notes, we watched Hank and crash course #2 on action potentials (see below) - and the last quick video animation (see below). The last half of class just working on 2 handouts; Cells of the N.S., and Nerve & Synapse Homework.
  4. Monday (1/16): No School
  5. Wednesday (1/18): Watched 4 videos on neurons, received two papers, one called "Reaction Time," the other a two page paper called the "Anatomy of a Synapse."
  6. Friday (1/20): Quiz - Neurons. Watched "Stabbed in the Brain," the story of Phineas Gage. Received a 3 page hand-out on Phineas. Also watched "Brain Power."
  7. Monday (1/23): Guest Speaker - John Weitzel (Albony Fire Dept.)
  8. Wednesday (1/25): Notes: The Brain (reading/homework assignment called Brain Dysfunction - see pages 251-253-see last slide of notes). Some video clips on the brain (see all below), Lab: Sheep Brain Dissection, two papers: Sheep Brain Dissection (3 pages), and a one page paper called Brain Worksheet. I have a lot of brain videos and each class may watch a different one...
  9. Friday (1/27): Notes: The Spinal Cord & Cranial Nerves. 2 handouts, one called spinal cord dissection, the other cranial nerve coloring. We also watched a bunch of video clips (all can be seen below.)
  10. Monday (1/30): Only 1 handout, a cross-word puzzle on the N.S. We watched a part of the documentary on the brain (can see below.) Taking notes on this documentary can be used as extra credit.
  11. Wednesday (2/1): Notes: Mostly review of the cranial nerves w/just a bit on the ANS. Continued to watch the The Human Brain video, and got two handouts: a four page memory lab, and a nerve review sheet.
  12. Friday (2/3): Almost finished "The Human Brain," did the 2-Pt. Touch test lab, and got a review sheet for next Wednesday's test. Also watched Hank's video on the ANS.
  13. Monday (2/6): Optical Illusion Presentation. Test on the NS is next class.
  14. Wednesday (2/8): Watched the video "Pushing the Limits: Sensation," played two KaHoot Games, then took the partner test on the Nervous System. This ends the unit, so go to the next unit on the Senses. Adios.

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 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).
