The Human Brain
Which of the following is not one of the three major characteristics of the human brain?
The human central nervous system contains which of the following structures?
The brain and the spinal cord
The cerebrum and the cerebellum
The limbic system and the frontal cortex
The amygdale and the hippocampus
Renata was walking to her car in a dark parking lot, when she heard a strange noise and footsteps behind her. She felt her heart start to race, her breathing got faster and shorter, and the pupils of her eyes dilated. From your study of psychology, which part of Renata’s nervous system was activated?
The autonomic nervous system
The parasympathetic nervous system
The central nervous system
The sympathetic nervous system
Conscious control of our body’s functions is handled by the __________ nervous system, while unconscious (unaware) body functions are controlled by the __________ nervous system.
When a construction crew builds a house, the most basic building block of that structure is a brick. In the very same way, the most basic unit of communication in the human nervous system is the __________.
The telephone wires that lead from your home to the homes of friend, relatives, and even strangers are all covered by a thick, protective tube that insulates them from damage. This tube helps eliminate damage from things like water, birds’ feet, bugs, dirt, weather, tree branches, and other potential interruptions in communication. In the human neuron, the same sort of protection is provided by the __________.
The electrical charge of the neuron during its __________ potential is negative, while the electrical charge of the neuron during its __________ potential is positive.
__________ refers to the brain’s ability to adapt, grow, and change.
Specifically designed to help keep you alive, __________ are rapid and automatic neuromuscular actions generated in response to a specific stimulus.
The spinal cord connects the brain to the __________ nervous system.
Why is it that when people suffer serious spinal cord injuries that they are not able to regain control of functions lost as a result of the injury?
Because the spinal cord has two different segments to it – anterior and posterior – and only damage to one of those two segments can be repaired.
Because the surgery to repair a damaged spinal cord always results in a comprehensive loss of bodily control.
Because the spinal cord repairs itself in a way that that makes functions less controlled and more automatic.
Because the spinal cord is unlike other tissue in the body in that it is unable to repair itself.
Famed actor Christopher Reeve suffered a spinal cord injury as a result of a horse-riding accident. Until his death several years later, Mr. Reeve required the assistance of a respirator, a machine that artificially controlled his breathing. Additionally, he was virtually unable to use any part of his body below his neck and required a tremendous amount of daily assistance. Which part of the spinal cord was damaged in Christopher Reeve’s horse-riding accident?
The cervical spine
The lumbar spine
The thoracic spine
The sacral spine
The __________ is responsible for survival-oriented functions such as breathing, cardiac function, and basic arousal.
somatic nervous system
Which structure (or set of structures) in the human brain is/are most responsible for experiencing emotions?
The cerebral cortex
The basal ganglia
The limbic system
Which structure that is generally considered to be part of the limbic system is responsible for creating and storing memory files and for retrieving those memories when they are needed or wanted in the future?
The cingulated cortex
The striate nucleus
Evolutionarily speaking, which part of the brain is the newest? That is to say, which part of the brain appears to have developed the most recently?
The cerebral cortex
The cingulate cortex
The corpus callosum
When you were a very young child, you may have been warned repeatedly by your parents about avoiding activities that would cause you to “hit your head.” Specifically your mother was probably worried about you doing anything that would cause you to fall backward and strike the rear-most portion of your head on the ground. If you were to have such an unfortunate fall, which lobe of the cerebral cortex would you be most likely to damage?
The frontal lobe
The temporal lobe
The parietal lobe
The occipital lobe
Which parts of the body get the most “space” and attention in the primary somatosensory cortex of the parietal lobe of the cerebral cortex?
What is the best explanation for the stark similarities between the homunculus of the primary motor cortex and the homunculus of the primary somatosensory cortex?
The homunculi are so similar because they are redundant systems that “back” each other up.
The homunculi are so similar because they are located so close together.
The homunculi are so similar because they are both mediated by the functions of the thalamus.
The homunculi are so similar because movements require immediate sensory feedback.
Who is most likely to have some amount of language functioning controlled by both hemispheres of their cerebrum?
