2025/2026 WITH CORRECT/ACCURATE
ANSWERS
this is a collection of cell bodies found in the peripheral nervous
system
ganglia
the neuron pictured below is best described as
bipolar
This part of the autonomic system accelerates the heart beat and
increases breathing rate.
sympathetic nervous system
, which of the following statements is true concerning the
neuromuscular junction
The NMJ terminates on a muscle fiber
What prevents continuous stimulation of a nerve synapse and
how is this accomplished?
the short existence of neurotransmitters in the synapse prevents
continuous stimulation. some synapses contain enzymes that
rapidly inactivate neurotransmitters and other synapses rapidly
absorb the neurotransmitter
what neurotransmitter helps regulate emotional responses and
muscle tone?
dopamine
T/F: action potentials travel in one direction within the same
neuron
true
T/F: reflexes occur slower than a conscious decision to move from
the brain
false
In a reflex, the ____________ neuron conducts nerve impulses along
a pathway towards the central nervous system.
sensory/afferent
This part of a reflex is inside the CNS, made up of one or more
