This is a collection of cell Ganglia
bodies found in the peripheral
nervous system.
This part of the autonomic Parasympathetic
system increases digestion.
The dorsal root of a nerve Sensory (Afferent)
contains what type of
neurons?
This part of a neuron conducts Dendrites
nerve impulses towards the
cell body.
An interneuron inside the D. Central nervous system
spinal cord is part of the:
The neuron pictured, below, is Multipolar
best described as:
True or false: Neurons do not True
physically touch one another.
,Describe the synthesis and The neuron cell body manufactures
storage of neurotransmitters. neurotransmitters, which are stored in
secretory vesicles at the end of axon
terminals.
An afferent neuron carries From the peripheral to the central
information: nervous system
A postsynaptic neuron would After the synapse
be found:
What is the location and Location: Central nervous system (CNS)
function of Astrocytes? Function: Regulation of chemical
environment inside CNS, forming a
physical barrier (blood-brain-barrier) by
wrapping around blood capillaries
A patient's left thumb was Yes; Peripheral nerves can regenerate
severed in a cooking accident the length of the axon through axonal
and then reattached during regeneration because of the growth of
surgery. Would the patient be Schwann cells ahead of the axon.

Which of the following is true It must remain in constant operation to
concerning the sodium- maintain the resting state.
potassium pump?
True or false: A sensory False
neuron is signaling the body
of a light touch. This means
that the strength of the action
potential is weaker than usual.
Explain your reasoning.
Which of the following The NMJ terminates on a muscle fiber.
statements is true concerning
the neuromuscular junction?
What prevents continuous The short existence of neurotransmitters
stimulation of a nerve synapse in the synapse prevents continuous

enzymes that rapidly inactivate
neurotransmitters and other synapses
rapidly absorb the neurotransmitter.

found at the neuromuscular
junctions?
