Match the function with the correct lobe of the brain.
Vision
Attention
Planning
Responsible for touch, feeling pressure and temperature.
Understanding speech
Problem Solving
Decision making
Hearing/ auditory processing
Frontal
Parietal
Occipital
Temporal
What is the function of the spinal cord?
movement and balance
relays messages from the body to the brain
controls breathing and heart rate
controls body temperature, digestion, and sleep
What is the function of the brainstem?
hearing
movement and balance
involved in judgement, higher level thinking and planning
controls breathing and heart rate
Match the function or description to the part of the brain.
Coordinates movement
Largest part of the brain
Responsible for balance
Controls heartbeat, breathing, and blood pressure
Made up of the left and right hemisphere
Cerebrum
Brain stem
Cerebellum
What does the peripheral nervous system primarily control?
Only voluntary muscle movements
Only sensory information transmission
Voluntary and involuntary muscle movements and bodily functions.
Only involuntary processes like digestion
Which system sends signals to muscles from the brain?
Sympathetic nervous system
Autonomic nervous system (within the peripheral nervous system)
Central nervous system
Somatic nervous system (within the peripheral nervous system)
What is a function of the autonomic nervous system?
Controls voluntary movements
Regulates involuntary bodily functions like heartbeat and digestion.
Processes sensory information
Transmits signals to skeletal muscles
Which are true about the sympathetic and parasympathetic nervous systems? (select all that apply)
The parasympathetic nervous system calms bodily systems and maintains normal functioning
They are both part of the central nervous system.
The sympathetic nervous system controls muscle movements.
They are both part of the autonomic nervous system.
The sympathetic nervous system controls "fight or flight" responses.
What is the main function of dendrites in neurons?
Receive signals from other neurons.
Transmit signals to other neurons.
Release neurotransmitters into synapse.
Insulate the neuron for protection.
What role does the axon play in neurons?
Control cell metabolism and energy.
Conduct impulses away from the cell body.
Store neurotransmitters for release.
Receive signals from other neurons.
What is neurotransmission?
The growth of new neurons.
The process of sending signals between neurons.
The insulation of the axon.
The metabolic process in neurons.
Which part of the neuron releases neurotransmitters?
Soma of the neuron.
Axon terminals at the synapse.
Dendrites of the neuron.
Cell body of the neuron.

Which method uses magnetic fields to create brain images?
MRI scans brain structure with magnets.
PET scans identify metabolic activity with glucose.
CAT uses X-rays to capture brain injuries.
EEG measures electrical activity in brain.
Which technique is used for showing brain activity over time?
PET for metabolic processes
MRI for detailed anatomy
CAT scans for structural images
EEG
What can fMRI scans help researchers understand?
Patterns of human respiration during sleep.
Personality differences in individuals.
Social behavior patterns in animals.
Brain regions involved in specific cognitive tasks.
Before the development of neuroimaging, how did scientists study brain functions?
cadaver studies
lesion studies
case studies
all of these
In what way can genetics affect behavior?
Behavior is purely random, not genetic.
It increases likelihood of certain behaviors occurring.
Genetics guarantees specific behaviors will manifest.
Genetics always override environmental factors.
How do researchers study genetics and behavior correlation?
Evaluating behavior purely through personal interviews.
By comparing behaviors in genetically similar individuals.
Using surveys to gather opinions on behavior.
Only observing social interactions in children.
Match each type of brain scan with its description.
fMRI
measures electrical activity in the brain over time
EEG
Uses X-ray technology to take pictures of cross sections of the brain
PET scan
uses magnetic fields to get a picture of the brain's anatomy
MRI
uses magnetic fields to get a picture of brain function by measuring blood flow and O2 levels
CAT (CT) scan
uses a radioactive "tracer" to measure activity in different parts of the brain
