QuestionAnswer
There are two types of synapses—the electrical synapse and the __________ synapse. Chemical
Neurons are the only living cells that maintain a difference in the concentration of ions across their membranes. True or False False
In a myelinated neuron, the impulse can travel under the myelin between nodes of Ranvier. True or False False
The brief period during which a local area of an axon's membrane resists re-stimulation is called the __________ period. Refractory
An ion channel that opens in response to a sensory stimulus is a(n) Stimulus-gated channel
A neurologist is using a voltmeter to measure potential. The membrane potential of a neuron was recorded at +30 mV. This is what type of membrane potential? Action
Which chemicals allow neurons to communicate with one another? Neurotransmitters
If the threshold potential is surpassed, the full peak of the action potential is always reached. True or False True
In depolarization the membrane potential moves toward zero, whereas in hyperpolarization the membrane potential moves away from zero. True or False True
he speed of a nerve impulse depends on the neuron’s resting potential. True or False False
When a neuron is resting, the inner surface of its plasma membrane is slightly positive compared with its outer surface. True or False False
The magnitude of the action potential peaks when the sodium channels close. True or False True

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.
