Total questions: 37
Worksheet time: 1hrs 2mins
The __________ look like branches coming off the soma and are responsible for receiving information from other neurons.
axons
myelin
dendrites
axon terminals
The axon:
releases neurotransmitters across the synapse.
controls the metabolism and maintenance of the neuron.
protects the neuron from potential chemical and physical interference.
carries information towards the cells that communicate with that neuron.
Which two parts constitute the autonomic nervous system?
brain; spinal cord
sensory nerves; motor nerves
brain; somatic nervous system
sympathetic nervous system; parasympathetic nervous system
The parasympathetic nervous system is not responsible for:
dilating the pupils.
contracting the bladder.
stimulating salivary glands.
slowing the heart rate and dilating arterioles.
What is space between two neurons called?
axon
soma
synapse
dendrite
Where are neurotransmitters released from?
myelin
dendrites
glial cells
terminal buttons
When we receive signals and then transmit signals, different neuron structures in the brain activate. In what order do these neuron structures activate?
axon, nucleus, myelin, dendrites
dendrites, soma, axon, axon terminals
soma, dendrites, axon, axon terminals
dendrites, axon terminals, soma, axon
Jeremy was swimming in the ocean last Saturday and saw a shark in the water. Jeremy panicked and swam as fast as he could to the shore.
Identify what system helped Jeremy get out of the ocean.
somatic nervous system
central nervous system
sympathetic nervous system
parasympathetic nervous system
The functions of the autonomic nervous system are said to be __________, though some can be __________ triggered.
voluntary; forcefully
passive; involuntarily
voluntary; involuntarily
involuntary; voluntarily
Tobin was watching his young children play on the beach. He noticed that his toddler had ventured into the water. In panic, Tobin ran into the water and didn’t notice that his leg had been badly injured until he had got his son out of the water. What is involved in this situation?
synapses
homeostasis
interneurons
fight–flight–freeze response
Savannah knows her pet rabbit has very soft fur. Identify what type of neuron helps Savannah understand this.
interneuron
motor neuron

neuron; dendrites; myelin sheath; axon; soma
dendrites; neuron; myelin sheath; soma; axon
dendrites; neuron; axon; axon terminals; nucleus

Miranda is a sculpture artist, and part of her work involves putting clay into a kiln. One day, when removing pieces from the kiln, Miranda drops one she had been working on. She can’t work out why she dropped it; it was hot but she was telling herself not to drop it.
Why might Miranda have dropped the artwork?
Miranda didn’t like the piece of art.
Her motor neurons told her sensory neurons it was too hot.
Her interneurons communicated quicker than she was thinking.
Her sensory neurons carried a message to tell her muscles to let go.
Information from your central nervous system is communicated to the body’s organs via:
interneurons
motor neurons
the spinal cord
sensory neurons
Laurie was driving home last week when he was threatened by a group of men with weapons. Laurie felt his heart rate quicken and panic set in. Laurie’s bladder released and he felt himself running quicker than he had ever run before.
Select the system that activated to help Laurie make it to safety.
interneurons
somatic nervous system
sympathetic nervous system
parasympathetic nervous system
Nerves that cause muscles to move are ____.
axon nerves
motor nerves
sensory nerves
feeling nerves
The ____ is made of all the nerves that spread out from the brain and spinal cord.
peripheral nervous system
average nervous system
central nervous system
linear nervous system
Which two parts constitute the autonomic nervous system?
brain; spinal cord
sensory nerves; motor nerves
brain; somatic nervous system
sympathetic nervous system; parasympathetic nervous system
What is considered the command center of the nervous system?
