Nervous Overview Objectives

List the organs and functions of the central and peripheral parts of the nervous system.
Describe the somatic and autonomic components of the motor response.
Indicate the locations of some of the nerves of the peripheral nervous system, including the sciatic nerves, median & ulnar nerves, and cranial nerves.

The nervous system not only keeps us breathing and circulating blood, it also can solve complex problems like a Rubik’s cube.

We are starting our examination of the nervous system with two brief and complementary overview videos.

Nerves are bundles of neurons (nerve cells) that (1) receive sensory information, (2) send it to the central nervous system (brain and spinal cord) for processing, and then (3) respond in some motor fashion, like causing muscle to contract.

The motor nerve response is voluntary and under our control is called _____, are the nerve response that is involuntary and out of our control is called _____.

The autonomic (sometimes called “vegetative”) part of the motor nervous system has two components that generally work opposite each other: the _____ that often stimulates organ activity, and the _____ that often inhibits organ activity.

The nerves are often running along large blood vessels throughout the body.

Sciatic Nerves

Run from the lumbar region of the spine down the back of each leg.

Median and Ulnar Nerves

Run down each forearm and through the wrist.

Cranial Nerves

Several sets of nerves that extend from the cervical spine to the brain.

Start Your 6A Media Assignment here

Watch the video below on the human biology portfolio and complete this media assignment.

In Guide 2A you selected a possible portfolio format and also a few pieces of work that could fit the outcomes. In this assignment you will be committing to a portfolio format and completing one of the nine sections of the final portfolio. You can find the nine learning outcomes here and on Canvas.

For your portfolio update media piece you are turning in a completed part of your final portfolio; one of the nine learning outcome sections.

- Use the format your final portfolio will be in. For example, this may be a powerpoint slide, a handmade journal page, a webpage, or whatever format you are using. If you are hosting your portfolio on a website, you can submit the web address in the comment box. Make sure the graders have access to whatever you are submitting.
- Label the page/slide with which learning outcome is being met (for example: biology concept; science skills; or human biology connection).
- Include your original work that represents the learning outcome. This needs to be substantial, which typically means at least two pieces of work. For example, you may have one entire media piece and a quiz answer representing a single learning outcome.
- Along with your work representing the learning outcome, include a sentence or two caption that states how your work matches this particular outcome. For example, if you made a comic of the various organ structures and functions of the digestive system, you could state how your comic art is an example of a human biology connection.
- If you utilize anyone else’s work, like a photo from the internet, it needs to be fully cited (accessible web address) next to the work. Note that we are only crediting and grading your personal and original work, so you can include other cited images for reference, but they will not make up this assignment’s or your final portfolio’s grade.

Upload to Canvas a completed section (one of nine outcomes) of your final portfolio. This includes:

A. the name of the outcome you are completing (one of the nine).

B. at least two examples of your original work in your chosen final portfolio format that represents that outcome. For example, if you select the “science skills” outcome, you would have two pieces of original work that represents science skills.

C. a caption that explains how your work relates to the outcome. This can be short, like “An aspect of Biology Concepts is how structure relates to function. This media piece and quiz response relate skeletal and muscular structures to how they specifically function.”

D. Upload a single file to Canvas.

Outcomes List

The next section introduces the neurons that communicate and the glial cells that support them.

Check your knowledge. Can you:

list the organs and functions of the central and peripheral parts of the nervous system?
describe the somatic and autonomic components of the motor response?
indicate the locations of some of the nerves of the peripheral nervous system, including the sciatic nerves, median & ulnar nerves, and cranial nerves?
