SCRIPT QUESTIONS WITH
SOLUTIONS GRADED A PLUS
◉ glia. Answer: support the neurons in many ways--insulating,
synchronizing activity, removing waste
◉ cell body. Answer: contains nucleus
◉ dendrites. Answer: widely branching ("tree"), receive
transmissions
◉ axon. Answer: single, long, thin, straight fiber, branches at tip
◉ action potential. Answer: excitation that travels along an axon at a
constant strength
◉ resting potential. Answer: electrical polarization across
membrane
◉ terminal bouton. Answer: presynaptic ending
,◉ neurotransmitter. Answer: chemical that can activate receptors on
other neurons
◉ post-synaptic neuron. Answer: neuron on receiving end of
synapse
◉ Parkinson's disease. Answer: 1% of people over 50; difficulty
initiating voluntary movement, slow movement, tremors, rigidity,
depression
◉ dopamine. Answer: neurotransmitter
◉ physiological explanation. Answer: describes mechanism that
produces a behavior
◉ evolutionary explanation. Answer: relates behavior to the
evolutionary history of the species
◉ electroencephalograph (EEG). Answer: uses electrodes on the
scalp to record rapid changes in brain electrical activity
◉ magnetoencephalograph (MEG). Answer: records magnetic
changes
, ◉ positron-emission tomography (PET). Answer: records
radioactivity of various brain areas emitted from injected chemicals
◉ functional magnetic resonance imaging (fMRI). Answer: uses
magnetic detectors outside the head to compare the amounts of
hemoglobin with and without oxygen in different brain areas
◉ central nervous system. Answer: brain and spinal cord
◉ peripheral nervous system. Answer: bundles of nerves between
the spinal cord and the rest of the body
◉ cerebral cortex. Answer: outer covering of forebrain
◉ occipital lobe. Answer: rear of head, specialized for vision;
damage causes cortical blindness
◉ temporal lobe. Answer: sides of head, hearing and complex
aspects of vision
◉ parietal lobe. Answer: forward from occipital, specialized for body
senses
