NEURONS
What part of a neuron receives incoming messages?
Dendrites
What two structures make up the CNS?
Brain and spinal cord
What brain structure controls balance and coordination?
Cerebellum
Which scan records electrical activity across the brain's surface?
EEG
Which lobe is located at the front of the brain?
Frontal lobe
What fatty covering helps neural signals travel faster?
Myelin Sheath
Which part of the PNS controls voluntary movement?
Somatic Nervous System
Which structure regulates breathing, heart rate, and blood pressure?
Medulla
Which scan uses magnetic fields and radio waves to create detailed images of soft tissue?
MRI
Which lobe is primarily associated with visual processing?
Occipital lobe
What is the tiny gap between one neuron's axon terminal and another neuron's dendrite?
Synapse
Your heart starts racing because you are suddenly frightened. Which division is responsible?
Sympathetic Nervous System
Which structure acts like a “traffic director” for much of the brain's incoming sensory information?
Thalamus
Which scan uses a series of X-rays taken from different angles to show brain structure?
CT Scan
Which lobe processes touch, bodily sensations, and spatial information?
Parietal lobe
According to the all-or-none principle, what happens once a neuron reaches threshold?
It fires completely
After a stressful situation ends, which division helps decrease heart rate and return the body toward normal?
Parasympathetic nervous system
Which structure is especially important for forming new declarative memories?
Hippocampus
Which scan tracks a radioactive form of glucose to show patterns of brain activity?
PET Scan
What area of the brain is important for language and speech production?
Broca's area
Put these in the correct order: axon terminals, dendrites, axon, cell body/soma.
Dendrites → Cell Body/Soma → Axon → Axon Terminals
What is the main difference between the CNS and PNS?
CNS = brain & spinal cord; PNS = nerves outside the brain/spinal cord that connect the CNS to the rest of the body
A person is awake but has major difficulty with alertness and arousal after brain damage. Which structure may have been affected?
Reticular formation
A researcher wants to know when, down to milliseconds, the brain responds to a sound. Which technique would be most useful?
EEG
What is the difference between the longitudinal fissure and corpus callosum?
Longitudinal fissure separates the hemispheres; corpus callosum connects them
