| In its resting state, what charge is the neuron? | show 🗑
|
||||
| How does the neuron prevent positive and negative ions from mixing between the outside and inside of the cell? | show 🗑
|
||||
| How does a neural reaction begin? | show 🗑
|
||||
| show | the minimum amount of neurons received to start the action potential, or "neural firing"
🗑
|
||||
| How does the neuron change to start the action potential? | show 🗑
|
||||
| show | the change in charge spreading down the length of the neuron; a.k.a. electric message firing
🗑
|
||||
| show | the neuron releases its neurotransmitters across the synapse to the other neuron
🗑
|
||||
| show | reuptake
🗑
|
||||
| show | The neuron either fires completely or it doesn't at all, but the intensity of the firing doesn't change if the firing happens. It will always fire completely.
🗑
|
||||
| What does an excitatory neurotransmitter do? | show 🗑
|
||||
| show | prevent the next cell from firing
🗑
|
||||
| show | yes
🗑
|
||||
| What direction does a neuron fire? | show 🗑
|
||||
| show | sensory neuron
🗑
|
||||
| show | interneuron
🗑
|
||||
| What kind of neuron takes information from the brain to the rest of the body? | show 🗑
|
||||
| In what order would the different kind of neurons act in? | show 🗑
|
||||
| What makes up the CNS (central nervous system)? | show 🗑
|
||||
| show | transmits information from the rest of the body to the brain
🗑
|
||||
| What makes up the PNS (peripheral nervous system)? | show 🗑
|
||||
| What is the somatic nervous system for? | show 🗑
|
||||
| What is the autonomic nervous system for? | show 🗑
|
||||
| show | parasympathetic nervous system
🗑
|
||||
| show | sympathetic nervous system
🗑
|
||||
| I accelerate some functions such as heart rate and blood pressure, and I conserve resources needed for a quick response by slowing down other functions like digestion. Am I the sympathetic or parasympathetic nervous system? | show 🗑
|
||||
| I slow down the body after a stress response. Am I the sympathetic or parasympathetic nervous system? | show 🗑
|
||||
| show | reflex
🗑
|
||||
| What is lesioning? | show 🗑
|
||||
| show | noticing changes after accidents, noticing changes after lesioning, EEG (electroencephalograph), CAT (computerized axial tomography), MRI (magnetic resonance imaging), PET scans (positron emission tomography), and fMRI (functional MRI)
🗑
|
||||
| show | Detects the types of brain waves produced during different stages of consciousness for generalizing about brain function
🗑
|
||||
| How does the CAT (computerized axial tomography) work & what does it do? | show 🗑
|
||||
| show | uses magnetic fields to measure the density & location of the brain material to create detailed images of brain structure
🗑
|
||||
| show | measures amount of certain chemical (ex. glucose) used by the brain to see what areas are most active during certain tasks. more used, higher the activity
🗑
|
||||
| show | combines techniques of MRI & PET scans to show details of brain structure with information about the brain flow and tying brain structure to brain activity during cognitive tasks
🗑
|
||||
| show | controls basic biological functions that keep us alive
🗑
|
||||
| show | medulla, pons, cerebellum
🗑
|
||||
| show | controls blood pressure, heart rate, & breathing
🗑
|
||||
| What does the pons do? | show 🗑
|
||||
| show | coordinates some habitual muscle movements & for balance
🗑
|
||||
| show | coordinates simple movements with sensory information
🗑
|
||||
| show | controls general body arousal and ability to focus our attention
🗑
|
||||
| What does the forebrain do? | show 🗑
|
||||
| show | thalamus, hypothalamus, amygdala, and hippocampus
🗑
|
||||
| show | receives sensory signals coming up the spinal chord and sending them to appropriate areas in the rest of the forebrain
🗑
|
||||
| What does the hypothalamus do? | show 🗑
|
||||
| show | experiences of emotion
🗑
|
||||
| show | memories, esp. new ones
🗑
|
||||
| What is the grey wrinkled surface of the brain that is largely densely packed neurons? | show 🗑
|
||||
| What are specialized functions of the left hemisphere? | show 🗑
|
||||
| What are the specialized functions of the right hemisphere? | show 🗑
|
||||
| What is a split brain? | show 🗑
|
||||
| show | any area of the cerebral cortex that isn't associated with receiving sensory information or controlling muscle movements; human thoughts and behaviors
🗑
|
||||
| What is the role of the prefrontal cortex in the frontal lobe? | show 🗑
|
||||
| What is the role of Bronca's area? | show 🗑
|
||||
| show | sending signals to muscles, controlling voluntary movements
🗑
|
||||
| show | receiving of incoming touch sensations from the rest of teh body
🗑
|
||||
| show | interpretation of messages from our eyes in our visual cortex
🗑
|
||||
| What is the role of the temporal lobe? | show 🗑
|
||||
| show | after damage to a part of the brain, dendrites might be able to make new connections in another part of the brain that would be able to take over the functions of the damaged part

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
