Leech Neurons Lab


1. What is the electrode measuring? Electrode measuring is a measuring system that uses an electrode to measure 1 or more electrode surface

2. Why use leeches in neurophysiology experiments? Well leeches seem to be easiest to use and they react better to the UV light

3. What is the difference between a sensory and a motor neuron? A sensory neuron is a unipolar neuron nerve cell that is within the nervous system. It is resposible for converting external stimuli of an organism into internal electric motor reflex loops for involuntary behavior and the avoidance of pain. Motor neurons are neurons in the central nervous system that by projecting axons control muscles indirectly and directly

4. Do you think a leech experiences pain? What is pain? I do not think that the leech experiences pain. Pain is something we feel as a result of injury or operation

5. What were the two most interesting things about doing this lab? I enjoyed this lab because it was very detailed picture and it takes you through step by step

6. Anything you found confusing or didn't like about the lab?Not really I thought it was very explanitoy and it was fun.
