It is well established that certain autonomic responses such as heart rate, perspiration, and respiration change under stress.
Physiological arousal is much the same for several emotions.
Joel's pupils become dilated, his digestion is reduced, and his skin becomes cold. Which system is controlling his bodily changes?
Sympathetic
Which part of the nervous system is most immediately activated by sudden fear?
Sympathetic
Which of the following biological systems is most likely responsible for an increase in heart rate while experiencing anxiety?
The sympathetic nervous system
Activation of the sympathetic branch of the autonomic nervous system results in
an increase in respiratory rate
Which of the following correctly pairs subdivisions within the major divisions of the human nervous system?
automatic... sympathetic and parasympathetic
A polygraph machine is often called a "lie detector," although it does not detect lies. Instead, it responds to changes in
autonomic arousal
The part of the neuron that is responsible for receiving signals from other neurons is called
dendrite
The autonomic nervous system is most directly involved in
digesting food
Which of the following is reduced during a fight-or-flight reaction?
digestion
Which of the following neurotransmitters has been linked to Parkinson's disease and schizophrenia?
dopamine
Which of the following neurotransmitters is most closely associated with schizophrenia?
dopamine
The primary effect of the myelin sheath is to
increase the velocity of conduction of the action potential along the axon
The role of the parasympathetic division of the autonomic nervous system is to
increase the velocity of conduction of the action potential along the axon
Mary participates in an exercise program because she experiences an increase in energy and feelings of well-being at the end of each exercise session.
increases her level of endorphins
The function of dendrites is to
receive information from other neurons
A person accidentally touches a hand to a hot stove and quickly pulls the hand away:
spinal reflex
Ben was enjoying a walk in the woods on a beautiful Saturday afternoon. As he went around a curve, he noticed a bear walking toward him.
sympathetic nervous system
Nervousness can result in faster and more shallow breathing as well as a racing heart. This is due to activation of the
sympathetic nervous system
Information is relayed to the spinal cord or the brain by
afferent neurons
Painkilling substances produced by the brain are known as
endorphins

sympathetic nervous system
Which of the following are NOT part of a neuron?
synapses
