Cardiac Cycles
Today in class we:
Discussed the electrical and mechanical conductions of the heart:

Activity:
- Students got into small groups. Each group got a general reading on neurotransmitters and how they are affected by drugs.
- Each group also received a reading for a specific drug.
- Due Tuesday:
Read and answer reading reflection questions on both the role of neurotransmitters and the affects of your specific drug on nervous system functions
Be prepared with your group to present on your specific drug
