1. Two main Divisions of the Nervous System:
2. Figure 28.1 A/B
Describe: a. Sensory Input b. Integration c. Motor Output d. Effector Cells e. Reflexes f. 3 types of neurons and their functions
3. Structure of a Neuron (Fig. 28.2) a. Label and describe the function of each part b. Describe how a signal moves through an axon
4. Nerve Signals the their transmission a. Describe how membrane potential is created b. Draw Fig 28.3B and describe the role of Na+ and K+ in the cell.

c. Fig. 28.4, 28.5 Describe the process by which a stimulus creates the action potential and then conduction of a nerve signal down the axon.
5. Neurons Communicate at Synapses a. What is the purpose of a synapse? b. Describe the two types of synapses. c. Fig. 28.6 Chemical Synapse. Draw and describe how a signal is transmitted through a chemical synapse. d. Describe the difference between Excitatory and Inhibitory synaptic terminals. e. List molecules that function as neurotransmitters and describe what they control:
Molecule Name Type of Molecule Controls f. Give examples of how caffeine, nicotine, alcohol, prescription drugs, and illegal drugs affect neurotransmitters.
6. Animal Nervous System a. Compare the nervous systems of Hydra, Flatworm, Leech, Insect, Squid, Human

Animal Type of Nervous System b. Describe how cephalization and centralization were important steps in animal evolution
7. Vertebrate Nervous System a. Fig 28.11A, B Draw and describe components and functions of CNS and
PNS of Vertebrate Nervous System b. Outline the two divisions of the Peripheral Nervous System. c. Outline the three divisions of the Autonomic Nervous system: Explain how the sympathetic and parasympathetic systems are opposing. d. Describe the embryonic development starting with three embryonic symmetrical “bulges” and ending with development of the cerebrum. Which

region of the brain has changed to most during the course of vertebrate evolution?
8. The Human Brain a. Draw /label the regions of the brain and outline their major functions b. Describe the brain activity during arousal and sleep. c. Which “system” of the brain is responsible for emotion, learning and memory. Describe the parts of the brain included in this system.
Parts of the Limbic System Controls……….. d. Describe the following Neurological Disorders:
Disease Symptoms Causes/Treatments
