Which of the following is NOT a function of glial cells? - correct answer-the conduction of
action potentials
The process of phagocytosis involves - correct answer-the removal of neuronal debris
Movement of the axon membrane potential from -70 mV to -90 mV would be called? -
correct answer-hyperpolarized
Saltatory conduction is rapid because? - correct answer-the action potential does not have to
depolarize every segment of the axon membrane
Sensory stimuli that vary in intensity are coded by variations in the ___________ of a
neuron? - correct answer-firing rate
Movements in the axon membrane potential from -90mV to -80mV would be termed? -
correct answer-depolarization
The structures that comprise the basal ganglia include the - correct answer-pitamen,
caudate nucleus and globus pallidus
The _________________ is considered to be the body's "master gland" - correct
answer-anterior pituitary
Damage to the _________________ would most likely be fatal? - correct answer-medulla
ablongata
Direct agnostic is direct antagonist as - correct answer-endogenous opiod is to naxlone
The muscle weakness associated with myasthenia gravis reflects? - correct answer-loss of
Ach receptors on skeletal muscles
_________________is the synthesis pre-cursor for dopamine? - correct answer-tyrosine

dopamine levels within neurons
One of the oldest methods used in neuroscience to study brain function
is________________ - correct answer-experimal
A key advantage of the fMRI technique is that this method can - correct answer-record
