How does the brain send messages

QuestionAnswer
Stimulus / Response Stimulus = Anything that causes an action or response. Response = An action which is the result of a stimulus.
Neuron A single nerve cell that transmits electric impulses.
Sensory Receptor A nerve ending that responds to a stimulus in the environment. ( We have them for touch, taste, hearing, sight and smell).
Motor Neuron Neurons that carry signals from the spinal cord to the muscles to produce movement.
Synapse The tiny gap between the axon of one neuron and the dendrite of another.
Axon A threadlike extension of a neuron that carries nerve impulses away from the cell body.
Dendrite A branch that extends from a neuron's cell body and receives incoming information.
Nerve The “electric wire” that makes up the brain and the structures of the nervous system.
Neurotransmitter A chemical that is released when an electric impulse reaches the end (axon) of a neuron.
Memory an experience that stimulates many of your senses and it causes a complex network of neurons to  be built (connected in your brain).

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.
