Leech

1.What is the electrode measuring?

The electrode is measuring the activity and the dye is showing the nerve impulse.

2. Why use leeches in neurophysiology experiments?

They are used because they have all the cells. The neurons are large in size and pretty easy to detect. This makes them ideal to perform this experiment on.

3. What is the difference between a sensory and a motor neuron?

The difference between sensory and motor neurons is that sensory feels, smells, taste, and hears things and sends that message (they also receive the message). A motor neuron is the ability to move or twitch. (they deliver the action message)

4. Do you think a leech experiences pain? What is pain?

I think that every living thing experiences pain to an extent. Although it may be lacking the same pain receptors that we have it may not feel any pain. I would have to say yes though.

5. What were the two most interesting things about doing this lab?

This whole lab was fascinating to me because it was so different. I love to
Take apart anything and learn how it functions and in this case the neurons!!

6. Anything you found confusing or didn't like about the lab?

No there wasn’t anything that I found confusing about this lab. It was very straight forward and had very detailed instructions.
