Parts of the Nervous System

Aim: What are the parts to the nervous system?

Do Now: What is the function of a neurotransmitter? What would happen if a neurotransmitter stayed bound to a receptor site for a long period of time?

Hand in HW

Review of HW pg 439 List and Describe the role of the three kinds of

neurons. What two parts of the brain are responsible for

controlling your balance and coordination? The synapse plays an important role in the

transmission of an impulse. What might happen if an impulse is unable to travel across a synapse for some reason?

List three feelings you might experience and describe what part of the autonomic nervous system will be most involved with each feeling.

Discussion Questions…

Based on the information about the nervous system how do you think a drug like aspirin might affect nerve impulses?

How do you think it might affect the sympathetic and parasympathetic nervous systems?

Aim: How do drugs affect the body?

Do Now: What is the difference between the sympathetic and parasympathetic systems.

HW: Pg 450 questions 1-5 due tomorrow.
