BIO 152 PRACTICE EXAM 2 (UK-
DANLEY) WITH CORRECT
ANSWERS 2025
Motor Neuron correct answers >> The electrical
communication cell of the nervous system.
True/False? Neurons can pass signals out to the tips and then
back to the cell body to gain information about their environment.
This process of electrical signalling is similar to the echolocation
used in bats. correct answers >> False. Remember, neurons
move signals in a one-way fashion.
Dendrite correct answers >> Receives incoming messages
Axon correct answers >> Conducts an action potential
Axon Terminal correct answers >> Part of the synapse
In a typical neural circuit, which type of neuron specializes in
relaying decisions about how to respond out to the various parts
of the body? correct answers >> Motor Neuron
Clusters of ganglia and axons that are located in one central
location of an animal body are known as _____________. correct
answers >> The central nervous system.
, Ganglia improved communication in ___________, allowing for
better processing of incoming information and coordination of
responses. correct answers >> Interneurons
The synaptic clefts of neuromuscular junctions are normally about
10 nm wide. If the width of the cleft were to be reduced to 5 nm,
what might be a visible response of the body to this change?
correct answers >> Skeletal muscle cells would depolarize
faster.
What allows some neurons to conduct action potentials faster
than others? Select all that apply. correct answers >> The
degree of myelination around the axon.
The axon diameter
At a chemical synapse the _____________ releases
neurotransmitters into the synaptic cleft. correct answers >>
Presynaptic cell
Which of the following correctly describe possible
structures/designs of neurons? Select all that apply. correct
answers >> -Dendrites are absent.
-A neuron has approximately 20 dendrite branches.
-An axon branches into about ten different synaptic (or axon)
terminals.
-The cell body is located about halfway down the length of the
axon.
The movement of potassium out of a resting neuron is a
consequence of: correct answers >> High concentration of
