Astrocytes Influence the Connectivity Between a Pre- and Postsynaptic Neuron

question 26

Multiple Choice

Astrocytes influence the connectivity between a pre- and postsynaptic neuron by

• A) causing additional storage of glycogen within neurons, thereby increasing their metabolism.
• B) increasing myelination of neurons, which results in faster action potentials.
• C) decreasing the permeability of blood vessels, thereby aiding in the supply of nutrients to neurons.
• D) taking up and releasing neurotransmitters and therefore altering the activity of neurons.
• E) conducting action potentials, which increase the flow of information.
