Exam 9: The Central Nervous System

The only fuel source for neurons under normal circumstances is ________.Low blood levels of this is termed ________,which can lead to confusion,unconsciousness,and eventually death.In order to synthesize enough ATP to continually transport ions,the neurons also exhibit high rates of ________ consumption.To supply these needs about ________% of the blood pumped by the heart goes to the brain.

For the structures listed below,choose one of the following: -corpus callosum

Match these brain areas with their descriptions. -composed of distinct regions of gray and white matter,a section of the brain that develops with sulci and gyri

Do the terms vertebral column and spinal cord mean the same thing? Explain.

There is a legend about an autopsy having been performed on a space alien in New Mexico,many decades ago.Assuming that this alien was as well-educated and trained on its planet as NASA educates and trains astronauts on Earth,what feature would be expected in the alien's brain?

Match these functions with the correct brain area. -network to coordinate arousal and sleep,but also involved in blood pressure regulation and pain modulation

Match these terms with their descriptions. -swellings containing sensory cell bodies

For the structures listed below,choose one of the following: -basal ganglia

Parkinson's disease affects the cerebral basal ganglia,resulting in tremors in limbs,slowness in beginning and completing movements,and other abnormalities of muscle control.The specific population of neurons involved degenerates and thus fails to produce the neurotransmitter dopamine.An obvious treatment option to try is to administer dopamine,yet this is completely ineffective at alleviating the symptoms.Propose a reason why this treatment fails,and a related alternative to address the dopamine deficit.(Hint: Think about how the brain protects itself from chemicals in the blood.)

Enhancement of the postsynaptic cell's response to a repeated stimulus is called

Match these brain areas with their locations. -temporal lobe

Match these functions with the correct brain area. -contains corticospinal tracts,the pyramids,and control centers for breathing,swallowing,and blood pressure

Angela is a student who listens attentively in class and recopies and elaborates on her notes from several textbooks the minute she gets home from school.She studies with a group that explains concepts to each other,and they write on a big blackboard while they work.She makes flashcards out of the few vocabulary terms she has a hard time keeping straight,and goes through those between classes and in spare moments.What kind(s)of memory are being developed by Angela,and by which methods?

Which functions in the control of movement?

Some types of antihistamines make one sleepy,others do not.This difference is partly attributed to a difference in
