Descriptives non-experimental methods; can only state what is happening
Dendrites receives info from other neurons
Soma processes info given by dendrites
Motor Neurons movement; sends signals from NS to rest of body
Neural Pathway more you use the pathway, the stronger/easier it becomes when used (neurons communicate w/ each other towards outcome
Chemical Signal sends signals using neurotransmitters; talks to neurons by releasing chemicals
Electrical Signal electrical impulse; message travels along Axon to AT (neural activation) occurs in one neuron
Types of Neurons Motor Sensory Interneurons
Neurons cell specific to NS; sends & receives information
Two Divisions of NS Central NS Peripheral NS
Neurogenesis neural creations; new neurons grow & develop when new things are experienced
Neuroplasticity flexibility of neurons or ability to adapt
Neuroscience science of NS (brain, spine, nerves) electrical and chemical signals
Correlation association of 2 variables; strongly related or no/low relation (NOT CAUSAL, PREDICTION)
Negative Correlation (-), 2 variables move in opposite direction; NO CONTROL/INFLUENCE
Positive Correlation (+), 2 variables move in same direction; cannot say one thing causes another
Myelin Sheath protects axon; speeds up transmission
Axon transmits message
2 Functions of Neurons chemical and electrical
Interneurons connectors/creates links among neurons; brain & spine
Axon Terminal end of neuron; allow for connectors w/ other neurons
Somatic NS (PNS) voluntary movements
Automatic NS involuntary movements
Transduction sensory neurons take info and converts to electrical and chemical signals
Central NS brain-interpret, connect, make decisions (heavy lifter) spine-basic decisions, reflex (automatic beh.)
Sensory Neuron eyes, ears, nose, mouth, skin; pick up physical stimuli/info

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
