Multiple sclerosis

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. Immediately his pupils dilated, he began to perspire, and his heart accelerated. These changes are most closely related to the function of the

sympathetic nervous system

The sequence of shifts in the electrical charge of a neuron is called

the action potential

Damage to the cerebellum would most likely result in which of the following problems?

A loss of motor coordination

The autonomic nervous system is most directly involved in

digesting food

Activation of the parasympathetic nervous system results in which of the following?

A decrease in heart rate

Which of the following is classified as an antagonist?

A tricyclic antidepressant, because they block serotonin and norepinephrine transporters.

Researchers looking to create a drug to reduce the symptoms of Alzheimer's disease would most likely focus their efforts on which of the following neurotransmitters?

Acetylcholine

The depletion of which of the following neurotransmitters is most closely associated with the symptoms of Alzheimer's disease?

Acetylcholine

Which of the following correctly describes the firing of neurons?

An all-or-none response

During the high-wire act, Grace walks along a rope suspended 30 feet above the circus floor. Which of the following is most involved in helping Grace coordinate her movements and maintain her balance during the performance?

Cerebellum

Which of the following allows the examination of living brain tissue visually without performing surgery?

Computerized axial tomography

Which of the following neurotransmitters has been linked to Parkinson's disease and schizophrenia?

Dopamine

In extreme cases, surgically severing the corpus callosum is a treatment for which of the following conditions?

Epilepsy

Juana accidentally touched a hot iron. She immediately drew back her hand. Which of the following is true about the withdrawal of her hand?

It was initiated in the spinal cord.

Which of the following is brain-imaging technique that produces the most detailed picture of brain structure?

Magnetic resonance imaging (MRI)

Beth received a hemispherectomy to treat a seizure disorder when she was two years old. However, by the time she was five years old, her cognitive abilities were the same as those of a neurotypical five year old. Which of the following best explains her abilities?

Neuroplasticity

Which of the following provides information regarding brain function by monitoring the brain at work through metabolism of glucose?

Positron emission tomography (PET)

In which of the following techniques do researchers inject a harmless, radioactive substance into the living human brain to examine activity?

Positron-emission tomography (PET)

Which of the following is true of a neuron in the resting state?

The inside of the cell membrane is negative compared to the outside.

Which of the following occurs when a neuron is stimulated to its threshold?

The movements of sodium and potassium ions across the membrane creates an action potential.

Neurotransmitters are typically stored in which of the following parts of a neuron?

The terminal buttons

The part of the neuron that is responsible for receiving signals from other neurons is called

a dendrite

Information is relayed to the spinal cord or the brain by

afferent neurons

A drug that has the effect of intensifying or mimicking a particular neurotransmitter can be characterized as

an agonist, because it intensifies the effects of a particular neurotransmitter

Curare blocks action at acetylcholine synapses and causes paralysis. This drug is an example of an

antagonist

Difficulty in typing smoothly on a keyboard would most likely result from damage to the

cerebellum

A participant in a study of music perception listens to music with electrodes attached to her scalp while data are collected on the activity of her brain. This technique is called

electroencephalography (EEG)

Painkilling substances produced by the brain are known as

endorphins

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. The best explanation for Mary's perseverance in the program is that exercise

increases her level of endorphins

The area of the brain stem that is important in controlling breathing is the

medulla

The brain's ability to adapt after it is damaged is known as

plasticity

The process by which neurotransmitters are reabsorbed into the neuron after it fires is called

reuptake

An image projected to the left visual field of a split-brained person will be processed in the

right visual cortex

During neuronal firing, the part of the neuron that acts as an insulator and conductor to speed the electrical impulse as it travels down the axon is

the myelin sheath

The time shortly after a neuron fires is referred to as

the refractory period

Damage to a small part of the occipital lobe would most likely result in a

visual deficit
