Exam 3: Neurons and Synapses

If a drug prevents the reuptake of a neurotransmitter, that drug could be classified as a/an _______ drug.

Neurotransmission occurs between which two sites?

Potassium channels open after positively charged sodium ions fill the neuron because the membrane potential has become electrically:

For a neuron to create an outgoing spike, it must first detect many _____ within a short period of time.

When a neuron is at rest, there is a _____ concentration of sodium on the outside of the cell.

Neurons depend on receiving _______ from other neurons in order to create an outgoing spike.

Similar to oligodendrocytes, Schwann cells:

Alcohol prevents the reuptake of GABA, making it an ______ drug.

The critical ions for creating an action potential are sodium and:

Electrical signals move down the axon into the presynaptic terminals, where they are converted into chemical signals that travel across the _____ to the postsynaptic targets.

If a neuron puts out a single spike, we can assume the presence of stimuli.

When a neuron is at rest, there is a ____ concentration of potassium on the outside of the cell.
