Hello class,
here's a link to the spinal cord image I showed you from earlier today. Here's another site with an image, also
Remember to label your slides in your diagrams.
Lindsay Gardner found a great site for myelinated axons. press the link on slide 80 to see different magnifications of this image.
Here's a great interactive review of action potential

Your assignment for today is as follows:
microscope component:
1. Diagram a neuron from the multipolar nerve slide. Label glial cells, nerve cell bodies, and extensions.
2. Diagram the point of contact between nerve and muscle. This is labeled muscle spindle, or neuromuscular junction, or motor end plate. Be sure to diagram the axon as well as the muscle cells.
3. Diagram the spinal cord slide. IMPORTANT: you should place your thumb over the light source to create a dark-field illumination of the side. The color difference is subtle between the parts of the spinal cord.
4. Be sure to list magnifications on all diagrams.
Internet component:
1. Use the following sites to explain the anatomical effects of the listed drugs:
sites of use:
mouse party
neuroscience for kids (I know this sounds insulting, but give it a try. its pretty good.)
alcohol chemistry and you
Drugs to explain:
Cocaine
THC (marijuana)
alcohol
nicotine
your choice

Class,
Homework reminder: read section 45.3 for wednesday.
Homework reminder: read section 45.3 for wednesday.
The totals that we reported for understanding (10 = great, 0 = confused) this content by class are
3rd period: 4.9
4th period: 4.1
6th period: 5.1
These are a few of the web sites that you might find helpful to increase your personal ranking:
movement of ions in action potential (used in class) Remember, there is no sodium potassium pump here. Here's a helpful reveiw of resting potential, also.

Welcome IB bears!
Today's homework:
review climate change information for tomorrow's presentations. Goto google and type in "GLOBAL WARMING FACTS". select the link to the Koshland museum site. Review the impacts of change.
Also, read the first two pages in 45.2 of the book on resting potential of nerve cells.
