Nervous System Test Review
Miss Rodriquez & Mr Pitts
Motor neurons carry impulses from the brain and spinal cord to the
A. Heart
B. Muscles and glands
C. Touch receptors
D. Bones and skin
What is represented by the number 1?
The gaps in the myelin sheath surrounding neuron extensions are
called
A. Schwann cells
B. Motor neurons
C. Myelin gaps
D. Nodes of Ranvier
What is represented by the number 2?
What is represented by the number 3?
Impulses moving from the brain to muscles and glands move through
• Autonomic nervous system
• Motor neurons
• Sensory neurons
• Central nervous system
What is represented by the number 4?
An action potential can be caused by
A. Resting
B. Cutting a neuron
C. Electrically stimulating a neuron
D. Drinking water
What is represented by the number 5?
Resting potential in neurons is restored by
• The sodium-potassium pump
• The calcium influx
• ATP from respiration
• Glucose from photosynthetic tissues in human skin and hair
What is represented by the number 6?
Refer to the diagram. What happens when an action potential
travels along a neuron
A. K+ ions are pumped into the axon
B. Resting potential does not change
C. A small part of the axon reverses polarity
D. Na+ ions rush out of the cell
What is represented by the number 1?
What is the function of brain area A?
There are many more sodiums outside a neuron than inside when
A. the action potential sweeps by
B. during the state of resting potential
C. a small part of the axon reverses polarity
D. an the neuron dies
What is the function of brain area B?
Which of the following involves 2 or 3 neurons, is not learned, and is
not a conscious thing?

D. Reflexes
What is represented by letter A?
What is the gap between these neurons called?
Extensions from a neuron that receive input are
A. Axons
B. Dendrites
C. Motor neurons
D. Autonomic neurons
Neurotransmitters are released into the synapse when
A. You are startled
B. An action potential reaches the end of the axon
C. An action potential reaches the end of the dendrite
D. You take morphine or other narcotic drugs
What is the function of brain area C?
What is represented by letter B?
Insulating axons and speeding the impulse transmission is the job of
A. Nodes of Ranvier
B. Dendrites
C. Sodium-potassium pumps
D. Myelin sheaths
What is the function of brain area D?
What is the function of brain area E?
What is represented by letter C?
The brain and spinal cord are the
A. CNS / Central Nervous System
B. PNS / Peripheral Nervous System
C. Motor Neurons
D. Sensory Neurons
What is the function of brain area F?
What is represented by letter D?
Messages from receptors are transmitted to the CNS by
A. Autonomic Neurons
B. Somatic neurons
C. Motor Neurons
D. Sensory Neurons
What is represented by letter E?
Pathways to and from the CNS are provided by the
A. Autonomic Neurons
B. Somatic neurons
C. PNS / peripheral nervous system
D. Sensory Neurons
What is represented by letter F?
Involuntary functions of the internal organs are controlled by the
A. Autonomic nervous system
B. Somatic nervous system
C. Motor Neurons
D. Sensory Neurons
The sympathetic nervous system responds to
A. Typical homeostatic moments
B. Situations involving relaxation
C. Situations of threat
D. Situations of low blood sugar
