_______ is a disease that gradually destroys the myelin sheaths of neurons in the
CNS - ANS - multiple sclerosis (MS)
\________ potentials are short-lived local changes in membrane potential that can
be either depolarized or hyperpolarized - ANS - graded
\_________ are found in the CNS and bind axons and blood vessels to each other
- ANS - astrocytes
\a gap between schwann cells in the peripheral system is called a ? - ANS - node
of ranvier
\a neuron that has as its primary function the job of connecting other neurons is
called an - ANS - association neuron
\A second nerve impulse cannot be generated until - ANS - the membrane
potential has been reestablished
\a stimulus traveling toward a synapse appears to open calcium ionchannels at
the presynaptic end, which in turn promotes fusion of synaptic vesicles to the
axonal membrane // TF - ANS - TRUE
\also called a nerve impulse transmitted by axons - ANS - action potential
\an exceptionally strong stimulus can trigger a response - ANS - relative
refractory period
\an impulse from one nerve cell is communicated to another nerve cell via the -
ANS - synapse
\an inhibitory postsynaptic potential (IPSP) is associated with - ANS -
hyperpolarization
\an insufficient stimulus - ANS - Subthreshold stimulus
\any stimulus below this intensity will result in no response in a nueron - ANS -
threshold stimulus
\area where nerve impulse is generated - ANS - trigger zone
\axon terminals release neurotransmitters - ANS - conducting region
\bipolar neurons are commonly - ANS - found in the retina of the eye
\cell bodies of sensory neurons may be located in ganglia lying outside the cns //
tf - ANS - true
\Collections of nerve cell bodies outside the CNS are called - ANS - ganglia
\different types of sensory input can have the sam ultimate effect - ANS -
converging circuit
\efferent nerve fibers may be described as motor nerve fibers // tf - ANS - true
\ependyman cells - ANS - help to circulate the cerebrospinal fluid
\feel-good neurotransmitter - ANS - norepinephrine
