SECTION 12
THE NERVOUS SYSTEM AND NERVOUS TISSUE
STUDY QUESTIONS
1. Which structure predominates in the white matter of the brain?
2. Which part of a neuron transmits an electrical signal to a target cell?
3. What neurotransmitter is released at the neuromuscular junction?
4. Which of these locations is where the greatest level of integration is taking place in the example of testing the temperature of the shower?
5. Which of the following substances is least able to cross the blood-brain barrier?
6. Which functional division of the nervous system would be responsible for the physiological changes during exercise (e.g., increased heart rate and sweating)?
7. Which term describes a bundle of axons in the peripheral nervous system?
As the neural circuitry of the nervous system has become more fully understood and robot- ics more sophisticated, it is now possible to integrate technology with the body and restore abilities following traumatic events. At some point in the future, will this type of technol- ogy lead to the ability to augmentour nervous systems? (credit: U.S. Army/Wikimedia Commons)
SECTION OBJECTIVES
1. Name the major divisions of the nervous system, both anatomical and functional
2. Describe the functional and structural differences between gray matter and white matter structures
3. Name the parts of the multipolar neuron in order of polarity
4. List the types of glial cells and assign each to the proper division of the nervous system, along with their function(s)
5. Distinguish the major functions of the nervous system: sensation, integration, and response
6. Describe the components of the membrane that establish the resting membrane potential
7. Describe the changes that occur to the membrane that result in the action potential
8. Explain the differences between types of graded potentials
9. Categorize the major neurotransmitters by chemical type and effect
