Question
1. Basic Structure and Function of the Nervous System
Briefly describe the basic functions of the nervous system.
Describe the two primary structural divisions of the nervous system.
What is the difference between gray matter and white matter?
Compare and contrast a "nerve" and a "tract."
Describe the functional divisions of the nervous system. In your response, consider the basic functions of sensation, integration, and response as well as how the body is controlled (somatic vs. autonomic).
2. Nervous Tissue and 12.3 The Function of Nervous Tissue
REVIEW (from histology): What are the three main parts of a neuron and their functions?
List the CNS neuroglia and their basic functions.
List the PNS neuroglia and their basic functions.
What is the function of myelin?
Explain the nerve pathways involved in the sensation, integration, and response of adjusting your shower to your preferred temperature. (Note: this is not a reflex, but a conscious decision to turn the water temperature up or down.)
3. The Action Potential
Describe the resting membrane potential.
List and describe the four types of gated ion channels.
Once a neuron reaches its threshold, an action potential begins near the axon hillock. Describe how the action potential spreads down the length of the axon.
Explain how the myelin sheath increases the speed of transmission of a nerve signal.
4. Communication Between Neurons
Explain the effects of EPSP and IPSP on the possibility that the cell will reach its threshold.
What is a synapse?
Using anatomical terminology, describe the events of how a presynaptic neuron can stimulate a postsynaptic neuron.
What are neurotransmitters? Give two examples.
