5 Written Questions

1. the level of stimulation required to trigger a neural impulse
2. tissue destruction. A brain lesion is a naturally or experimentally caused destruction of brain tissue
3. the area at the front of the parietal lobes that registers and processes body touch and movement sensations
4. the division of the peripheral nervous system that controls the body's skeletal muscles. Also called the skeletal nervous system
5. the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations

1. a the "little brain" attached to the rear of the brainstem; its functions include processing sensory input and coordinating movement output and balance
2. b a nerve cell; the basic building block of the nervous system
3. c "morphine within"--natural, opiatelike neurotransmitters linked to pain control and to pleasure.
4. d the intricate fabric of interconnected neural cells that covers the cerebral hemispheres; the body's ultimate control and information-processing center
5. e a condition in which the two hemispheres of the brain are isolated by cutting the connecting fibers (mainly those of the corpus callosum) between them

5 True/False Questions

1. parietal lobes → the portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgments

   True        False

2. corpus callosum → the large band of neural fibers connecting the two brain hemispheres and carrying messages between them

   True        False

3. motor neurons → neurons that carry outgoing information from the central nervous system to the muscles and glands.

   True        False

4. Wernicke's area → controls language expression-an aread of the frontal, usually in the left hemisphere, that directs the muscle movements involved in speech

   True        False

5. dendrite → the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron

   True        False
