Damage to Broca's area in the left cerebral hemisphere on the brain would likely result in which of the following?

• A repetition of the speech of others

• A loss of the ability to speak

• A loss of the ability to visually integrate information

• A loss of the ability to comprehend speech

• An inability to solve verbal problems

Answer explanation

Damage to Broca's area, which is on the left side on the frontal love of the cortex, controls the muscles of speech.

In the neuron, the main function of the dendrites is to

• release neurotransmitters to signal subsequent neurons

• preserve the speed and integrity of the neural signal as it propagates down the axon

• perform the metabolic reactions necessary to nourish and maintain the neurons

• receive input from other neurons

• connect the cell body to the axon

Veronica is having trouble balancing as she walks, and her muscles seem to have lost strength and tone. A neuroanatomist looking into her condition would most likely suspect a problem with Veronica's

• medulla oblongata

• right cerebral hemisphere

• cerebellum

• occipital lobes

• thalamus

Which of the following neurotransmitters is generally associated with the inhibition of continued neural signaling?

• Dopamine

• Adrenaline

• GABA

• Serotonin

• Acetylcholine

A phenotype is best defined as

• an observable trait or behavior that results from a particular genetic combination

• the underlying genetic composition of a species

• a biological unit within which genetic information is encoded

• a recessive genetic combination that remains physically unexpressed

• the genetic combination given by a parent to his or her offspring

John is constantly overeating and can't seem to control his appetite, no matter how hard he tries. It is possible that John may have damage in which of the following brain structures?

• Thalamus

• Pons

• Hypothalamus

• Amygdala

• Association areas

A demyelinating disorder, such as multiple sclerosis, would cause all of the following symptoms EXEPT

• a reduction of white matter in the central nervous system

• an increased rate of neuronal condition

• a slower propagation of signal along the axon

• a deficiency of sensation

• a decreased neuronal insulation

Which area of the brain is responsible for coordinating complex motor functions?

• temporal lobe

• amygdala

• hypothalamus

• pons

• frontal lobe
