MEYERS UNIT 3 Practice test questions (robb)

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

describes the firing of neurons

An all-or-none response

For most people, speech functions are primarily localized in the

leftcerebral hemisphere

Dopamine, norepinephrine, and acetylcholine are all

neurotransmitters that excite or inhibit a neural signal across a synapse

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

a dendrite

The brain scans of people with amnesia are most likely to show damage to the

hippocampus

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

medulla

true of the reticular activating system?

It regulates levels of arousal.

caffeine and nicotine are in the same class as this drug

cocaine

Would result from an injury to the medulla?

A life-threatening disruption of heartbeat and breathing

Damage to the cerebellum would most likely result in

A loss of motor coordination

If an individual has lost the ability to feel pain in the left arm, there is most likely damage to what area of the brain?

Right parietal lobe

The drugs that block the reabsorption of neurotransmitters in the synapse during neural transmission are

SSRIs

A person with damage to Broca's area would most likely demonstrate

difficultly with speech production

The autonomic nervous system is most directly involved in

digesting food

alcohol interferes with the brain's ability to form new memories in the

hippocampus

This drug is a antagonist

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

The depletion of this neurotransmitter is most closely associated with the symptoms of Alzheimer's disease?

Acetylcholine

Damage to this brain structure may cause the inability to detect the emotional significance of facial expressions, especially those demonstrating fear?

Amygdala

Brain damage to this part leaves a person capable of understanding speech but with an impaired ability to produce speech

Broca's area

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

Computerized axial tomography

alcohol is most accurately classified as what type of drug?

Depressant

Cocaine blocks the reuptake of which neurotransmitter?

Dopamine

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

Dopamine

Most glands in the human body are a part of which system?

Endocrine

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

Epilepsy

a brain-imaging technique that produces the most detailed picture of brain structure

Magnetic resonance imaging (MRI)

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

Positron emission tomography (PET)

A technique that researchers inject a harmless, radioactive substance into the living human brain to examine activity?

Positron-emission tomography (PET)

Significant damage to this part will cause a person to fall into a deep coma from which the person will be unable to awaken?

Reticular formation

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

The terminal buttons

A person will most likely develop aphasia as a result of damage to the

Wernicke's Area

Electrically stimulating a rat's amygdala would most likely produce which of the following?

aggression

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

When a person is suffering from severe pain, the type of drug that will best help alleviate that pain is

an opiate

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

antagonist

A polygraph machine is often called a "lie detector," although it does not detect lies. Instead, it responds to changes in

autonomic arousal

An individual with damage to Wernicke's area is most likely to have difficulty

comprehending a spoken request for information

technique involving electrodes attached to scalp

electroencephalography (EEG)

Painkilling substances produced by the brain are known as

endorphins

The part of the endocrine system that is responsible for overseeing and regulating the release of hormones across the entire body is the

hypothalamus

Give increase in energy and feelings of well being during exercise

increases her level of endorphins

pupils dilated, sweating, and his heart accelerated. These changes are most closely related to the function of the

sympathetic nervous system

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
