The nervous system makes sense of these stimuli, and reacts in ways that promote your survival. In this lab, you will model that communication process.  \nProcedure  \n1. Form groups of four and assign one student to each of the following roles: a sensor, arelayer, an interpreter, and an actor.  \n2. Brainstorm situations, such as touching a hot object, in which your senses receive information and you respond.  \n3. Model one situation. The sensor should describe what he or she senses to the relayer, who passes the information to the interpreter, who decides on a body response. The relayer then passes the response to the actor to act out the response.  \n4. Repeat Step 3 using different situations.  \nAnalysis  \nExplain What factors could cause the situations you modeled to vary in speed?  \nThe Effects of Drugs Make this Foldable to help you understand the positive and negative effects of drugs.  \nSTEP 1 Fold a sheet of notebook paper horizontally into thirds lengthwise.  \nSTEP 2 Open the folded paper and make a fold two inches from one of the long edges.  \nSTEP 3 As illustrated, draw lines to create three columns. Label the columns as shown.  \nVisit [biologygmh.com](biologygmh.com) to:  \n study the entire chapter online  explore the Interactive Time Line,  \nConcepts in Motion, Interactive Tables, Microscopy Links, and links to virtual dissections  \n access Web links for more information, projects, and activities  \n review content online with the Interactive Tutor, and take Self-Check Quizzes  \nUse this Foldable with Section 33.4. As you study the section, record what you learn about how drugs cause changes in the nervous system in the appropriate columns of your chart.  \nA column: Increase the rate at which neurotransmitters are synthesized and released. B column: Block the transmitter from leaving the synapse.  \nC column: Block normal activity by mimicking other chemicals.  \nChapter 33 • Nervous System 961  \nSection 33 .1  \nReading Preview  \nObjectives  \n◗ Identify the major parts of a neuron and describe the function of each.  \n◗ Explain how a nerve impulse is similar to an electrical signal, and how it moves along a neuron.  \nReview Vocabulary  \ndiffusion: random movement of particles from an area of higher concentration to an area of lower concentration resulting in even distribution  \nNew Vocabulary  \nneuron dendrite cell body axon  \nreflex arc action potential threshold node  \nsynapse neurotransmitter  \nCLE 3210.1.1: Compare the structure and function of cellular organelles in both prokaryotic and  \neukaryotic cells.
