Question 4

Question
Complex, organized communication system of nerves and neurons is the [blank_start]nervous system[blank_end] Includes all nerves lying outside the central nervous system is the [blank_start]peripheral nervous system[blank_end] Consists of the brain and spinal cord is the [blank_start]central nervous system[blank_end] Produces rapid physical changes to perceived threats and emergencies is the [blank_start]sympathetic nervous system[blank_end] Communicates sensory and motor information is the [blank_start]somatic nervous system[blank_end] Maintains normal bodily functions and conserves physical resources is the [blank_start]parasympathetic nervous system[blank_end] Regulates involuntary functions such as heartbeat and respiration is the [blank_start]autonomic nervous system[blank_end] Main organ of the nervous system, made up of billions of neurons is the [blank_start]brain[blank_end] Handles both incoming and outcoming messages to and from the brain is the [blank_start]spinal chord[blank_end]

Question 5

Question
Match the description to the appropriate region of the cerebral cortex Pavia slips and falls in the bathroom and bangs her head on the tile floor. She begins to see “stars” and flashes of light, indicating some activation of brain cells in the [blank_start]___________.[blank_end] Paul has auditory hallucinations where he thinks he hears the voices of demons, which involves activation of the [blank_start]________.[blank_end] Leilani suffered a brain injury in a car accident which left her with temporary numbness on the left side of her body, which likely involves her [blank_start]______.[blank_end] Albert was in an accident and is now unable to move his right hand, which likely suggests damage in the [blank_start]_____.[blank_end] Shirley had a severe head injury and now she blurts out whatever she is thinking, regardless of the social setting; this could be linked to damage to her[blank_start]_____[blank_end]
Answer
  • occipital lobe
  • temporal lobe
  • parietal lobe
  • frontal lobe
  • frontal lobe

Question 6

Question
Match the description to the brain region that is likely affected. After Larry was hit in the head by a baseball, his movements became jerky and uncoordinated, and he could no longer type or play guitar. The baseball likely damaged his [blank_start]______[blank_end]. In the third round of a boxing match, Bruno caught a right hook that snapped his head back; when he hit the canvas, his breathing stop. He likely experienced damage to his [blank_start]_____[blank_end]. Ever since he was in a car accident 6 months ago, Lily watches the same video day after day and responds to it as if she has never seen it before. Her sensory functions are intact, but she does not seem to be able to form new memories because of damage to her [blank_start]______[blank_end]. Janna has lost her senses of taste, sight, hearing, and touch because of a brain tumor in her [blank_start]_____[blank_end]. When researchers electrically stimulated a brain region in a cat, its back arched, its fur bristled, and it showed all the characteristics of feline rage and anger. The part that was stimulated was the [blank_start]_____[blank_end].
Answer
  • cerebellum
  • brain stem
  • hippocampus
  • thalamus
  • amygdala

Question 7

Question
Dendrites in the postsynaptic neuron pick up [blank_start]___[blank_end] from the synapse. If more [blank_start]___[blank_end] than [blank_start]___[blank_end] signals are received, the postsynaptic neuron fires. The [blank_start]___[blank_end] travels down the axon. If the axon is myelinated, the message travels more [blank_start]____[blank_end] When the message reaches the end of the axon, neurotransmitters are released from [blank_start]___[blank_end] into the synapse. In the adjacent neurons, the process begins again.
Answer
  • neurotransmitters
  • excitatory
  • inhibitory
  • action potential
  • quickly
  • terminal buttons

Question 8

Question
Once an action potential reaches the end of the axon, how does the information usually get to the next neuron?
Answer
  • The action potential jumps across the synaptic cleft to the next neuron in the form of an electrical impulse.
  • Potassium ions (K+) move back and forth between neurons to carry the information across.
  • Vesicles in the terminal buttons of the axon release neurotransmitters which float across the synaptic cleft to the next neuron.
  • Myelin acts as a bridge to transport it across the synaptic cleft.

Question 9

Question
When Liz is relaxing on the couch after lunch, her heart rate, blood pressure,breathing, and digestion all are functioning without any conscious effort on her part. This is because of a subdivision of the _______ called the ______ regulates these involuntary functions.
Answer
  • peripheral nervous system; autonomic system
  • peripheral nervous system; somatic system
  • central nervous system; somatic system
  • central nervous system; autonomic system

Question 10

Question
Which of the following represents the correct sequence for secretion of hormones?
Answer
  • organs of the body, endocrine glands, pituitary gland, hypothalamus
  • pituitary gland, organs of the body, hypothalamus, endocrine glands
  • hypothalamus, pituitary gland, endocrine glands, organs of the body
  • endocrine glands, hypothalamus, organs of the body, pituitary gland

Question 11

Question
The nervous system is to a _________________, as the endocrine system is to a ____
Answer
  • slow acting & sustained duration; fast acting & brief duration
  • fast acting & sustained duration; slow acting & brief duration
  • slow acting & brief duration; fast acting & sustained duration
  • fast acting & brief duration; slow acting & sustained duration

Question 12

Question
In considering a human characteristic, we could say that the _____ provides the options and the _____ determines which option is taken.
Answer
  • chromosome; genome
  • genome; environment
  • gene; genome
  • environment; genome

Question 13

Question
"Heritability" refers to:
Answer
  • the degree to which genes control a characteristic
  • the degree to which shared environments account for a shared characteristic among siblings
  • the degree to which an individual's characteristics come from their father and mother
  • an estimate of how much of the variation in a characteristic is due to known genetic variation
