CH3 QUIZ

A(n) ________ is the electrical signal that moves from the neuron's cell body down the axon to the axon terminals

action potential

Randolf is walking down the street of his hometown, after being away for several years, when he smells the scent of freshly baked pie coming from a local baker. He suddenly has vivid memories of walking down this street as a child, holding both of his parents' hands, and swinging between them, feeling relaxed and happy. This is because the sense of smell projects directly to the ________, which is responsible for emotional memories.

limbic system

The ________ is the difference in charge between the intracellular (inside) and extracellular (outside) of a neuron

membrane potential

Kelsey had a CT scan that showed a tumor in the right frontal cortex. Which of the following behavioral symptoms most likely prompted the scan to take place?

motor skill deficits in the left side of her body

Some people have had their corpus callosum severed for medical reasons - like seizures. They would only be able to verbally express to you about images shown to ________.

only the right visual field

Ainsley is participating in a study that aims to determine whether the occipital cortex becomes more active in response to moving versus stationary stimuli. When she arrives at the lab, she ingests a "tracer" and then enters the scanning machine. What type of brain imaging is most likely being conducted in this study?

positron emission tomography (PET)

The ________ of a neuron contain ________ that house neurotransmitters, the chemical messengers of the nervous system.

terminal buttons; synaptic vesicles

A particular electrical signal is being transmitted to a neuron via neurotransmitters, and is sufficient to generate an action potential. If the incoming electrical signal via neurotransmitters is doubled, the action potential will ________.

undergo no changes in strength, speed, or duration

Henry Gustav Molaison (H. M.) had brain surgery for which of the following reasons?

He had severe seizures.

Which of the following brain processes is not a function of the highly evolved cerebral cortex? [Hint: think reptilian brain functions.]

breathing

The two major divisions of the nervous system are the ________ and ________.

central; peripheral nervous systems

The somatosensory cortex is responsible for perceiving and processing ________.

cognition and emotion

Which one of the following processes does not occur to excess neurotransmitters in the synapse?

collection by scavenger vesicles left over from the neurotransmitter release

Selective serotonin reuptake inhibitors (SSRIs) are drugs commonly prescribed for ________.

depression

Dr. Parsons and her colleagues are doing a study comparing differences in brain activity levels between patients with schizophrenia and controls with no psychological disorders. Their hypothesis requires a high level of detail and good detection of differences over time. Which of the following is the best brain imaging technique to use?

functionalmagnetic resonance imaging (fMRI)

________ is a state of equilibrium, in which biological conditions (such as body temperature) are maintained at optimal levels.

homeostasis

One example of ________ is the differences between hemispheres in the areas underlying language function.

lateralization

The process by which neurotransmitters are chemically treated by enzymes and returned to their vesicle containers in the terminal button is called _________.

reuptake

Sensory and motor neurons of the ________ nervous system are associated with activities traditionally thought of as conscious or voluntary.

somatic

The axon to dendrite space between two neurons is called the ________.

synapse
