PSY 3B
Marcus lost his pinky finger in a fishing accident. If his brain demonstrates plasticity following the amputation, what is MOST likely to occur?
Brain areas adjacent to those responsible for his pinky will take over different functions.
The _____ nervous system incorporates the main set of nerves that carry involuntary and automatic commands that control blood vessels, body organs, and glands.
autonomic
While Nathaniel eats, he always chews with his mouth closed. This requires that he breathe through his nose, but he does not have to focus on this because his _____ nervous system allows him to do it automatically.
autonomic
_____ promotes neuron growth and increased synaptic connections in the hippocampus.
cardiovascular exercise
Charlese has a problem with anxiety. Her psychiatrist told her that her way of thinking about situations causes her adrenal glands to produce too much adrenaline and noradrenaline. If her anxiety originates in her brain, it is coming from her _____ nervous system, and if it originates in her gland, it is coming from her _____ nervous system.
central / peripheral
Compared with vertebrates, invertebrates lack a hierarchical organization of their:
central nervous systems
A ballet dancer's ability to make all the precise moves necessary in a complex ballet can MOST likely be credited to an area of the hindbrain called the:
cerebellum
The _____ system is responsible for releasing hormones into the bloodstream.
endocrine
A person who incurs damage to the amygdala is MOST likely to be impaired related to:
feeling frightened in a dark alley
Anesthetics work because they reduce activity in the reticular formation, an area that:
helps to maintain a balance between consciousness and unconsciousness.
Studies have shown that rats will press a bar that initiates stimulation of their _____ to the point of exhaustion. This demonstrates that this area is associated with reward and pleasure.
hypothalamus
If Jiemba is walking down the street by himself at night and thinks he hears footsteps behind him, he is NOT likely to experience:
increased hunger
damage to spinal cord
may sever the connection from the brain to the sensory and motor neurons.
A police officer was fatally wounded. He was shot in the head and immediately stopped breathing. It is MOST likely the bullet pierced his:
medulla
Damage to the _____ can be deadly, as this structure controls heart rate, respiration, and circulation.
medulla
Francisco is a long-distance runner, and it is important for his vital organs and functions such as breathing to be well coordinated. The structure in the hindbrain called the _____ keeps these synchronized to help him function as a successful runner.
medulla
When McKinley sees Tyler reach for a doughnut at work, she knows he is probably doing this because he is hungry. Researchers think _____ allow her to make this inference.
mirror neurons
Bella's leg was amputated because of diabetes. It has been months since the amputation, and she still sometimes feels as though she has an itch on her missing limb. The phenomenon Bella is experiencing is called _____ syndrome.
phantom limb
Last night, Rylee was reading about the organization of the endocrine system. She realized that the _____ is really like the chief executive officer of a large company because it dictates the release of hormones by the other glands.
pituitary gland
Kora lost her pinky finger in a hunting accident. A few years after the accident, she had a brain scan, which demonstrated that areas of her brain that previously responded when she moved her pinky now respond when she moves her index finger. This change demonstrates the _____ of the brain.
plasticity
Ikemba was in a serious motor vehicle crash in which he suffered significant head trauma. He has been in a coma for the past 3 months. Ikemba's coma was MOST likely caused by damage to the area of the hindbrain known as the:
reticular formation
A person who suffers damage to the cerebellum would MOST likely have trouble with:
walking on a tightrope (balance, movement, coordination)
