Match each region of a neuron to the category of ion channels (ligand-gated ion channels, voltage-gated calcium channels, or voltage-gated sodium and potassium channels) found there: Axon: Axon terminal: Dendrite: Axon hillock:

Match each type of membrane potential to its definition: The membrane potential at which voltage gated sodium channels open. The membrane potential that triggers the action potential. Threshold potential Change in membrane potential that may or may not reach threshold and that may be depolarizing or hyperpolarizing. Rapid, strong depolarization followed by immediate repolarization. This potential is self-renewing if the right ion channels are nearby. Answer Options: Resting Potential, Threshold Potential, Graded Potential, Action Potential

For the nervous system to convey information using electrical signals, the signals typically must be passed from one neuron to another. Oftentimes, this transfer of information across the synapse occurs via the release of neurotransmitters from the pre-synaptic terminal. When a large stimulus is detected in one neuron, it often conveys this information by releasing a larger amount of neurotransmitter into the synapse.

Which of the following neuron structure - function parings is incorrect? Axon - extension of cell body Dendrite - sensitive to chemical and electrical signals Cell body - contains cell nucleus Axon - transmits signals to neighboring cells Dendrite - unbranched receptor sites of signals from other neurons
