Bio 12: Studying for Nervous system

We have been using the following path of inquiry to learn about systems.

• Learn about the “bits”
• Learn how the “bits” work or interact.
• What happens if the “bits” or the process does not work.

So far we have studied :

Four systems

• Digestive
• Circulatory

the plumbing

the blood

• Repiratory
• Renal or Excretory System

By using the idea of the body as a machine or an automobile

Then we can see that these systems deal with :

• How does the body get fuel?
• How does the body move that fuel?
• How do we burn the fuel?
• How do we get ride of waste

The Challenge is how does the body coordinate sense:

1. What is going on outside of the body
2. Keep balance within the body
3. Coordinate a response to what is going on outside of the body.

So the Nervous system has cells to quickly send messages via electrochemical messages.

Here are some challenges

• How do the cells receive a message
• How do the cells send the message
• How do three types of cells work together to respond to a stimulus.

So..the bits

The nervous system can be divided into a peripheral system and a central system.

There are three types of nervous systems cells

1. Cells that can receive a message: Sensory
2. Cells that can transfer the message: Interneurons
3. Cells that can respond to interneuron message: motor

We can look at anatomical feature of these three cells to classify them.

So..

1. Which have myelin?
2. Which have a large central cell body?
3. Which has long dendrites?
4. Which has long axons?

To coordinate we can look at the “reflex arc” which coordinates all three cells to a quick response without any processing to the brain…

The thought “Ouch I stepped on a nail” follows the quick hop away from the nail.

A sensory receptor is any cell that can responds to a stimulus and send an electrochemical message to another nerve cell. A sensation may cause either an autonomic or somatic response.

What is somatic and autonic?

Can you coordinate the path of response or does it happen without thinking?

The path of our lessons.

1. We started off with an outline of notes.
2. We had a power point to look at the basics of neuron structures and functions.
3. We started off understanding sending a message from one cell to another.
4. We looked at the transformation of an electrochemical message to a chemical message that changes the permeability of a cell membrane.
5. We made a diagram to show how a graph shows a change in voltage within a cell.

For our first evaluation we are going to look at this journey.

When looking at your notes, focus on neurons, synapses,action potential and peripheral nervous system notes information

https://www.google.ca/#safe=strict&q=When+looking+at+your+notes%2C+focus+on+neurons%2C+synapses%2Caction+potential+and+peripheral+nervous+system+notes+information

Now ..looking at all these sites, which focus on the peripheral nervous system?

What can you find that is useful with this site?

http://www.kean.edu/~jfasick/docs/Fall_08_AP_1/Chapter%2011_Part%20I.pdf

From a large volume of information can you refine your search into smaller pieces and then put them into order?

The big picture

http://www.ptdirect.com/training-design/anatomy-and-physiology/the-nervous-system-2013-anatomy-and-function

http://www.emory.edu/ANATOMY/AnatomyManual/nervous_system.html

The individual pieces of the picture

Synapse

https://web.williams.edu/imput/introduction_main.html

Action potential

https://en.wikipedia.org/wiki/Action_potential

Peripheral

https://www.dartmouth.edu/~rswenson/NeuroSci/chapter_3.html

Now seek questions or exams about these pieces.

Do these questions focus on the right topics?

http://wps.pearsoned.co.uk/ema_uk_he_PX_biopsych/216/55486/14204563.cw/content/index.html

What about these?

http://highered.mheducation.com/sites/0072421975/student_view0/chapter17/multiple_choice_quiz.html

Now ..you can use your action potential sheet as a foundation for a study guide.

What things do you want to have?

You challenge is to answer higher level questions that include the word …why.

So try a few more questions to see how thorough your study guide is.
