Detailed explanation-1: -Astrocytes, shown in Figure 16.8a make contact with both capillaries and neurons in the CNS. They provide nutrients and other substances to neurons, regulate the concentrations of ions and chemicals in the extracellular fluid, and provide structural support for synapses.
Detailed explanation-2: -Astrocytes ensheath small arterioles and capillaries throughout the brain, forming contacts between ends of astrocyte processes and the basal lamina surrounding endothelial cells.
Detailed explanation-3: -Astrocytes have an intimate relationship with blood vessels in the brain as their endfoot processes completely envelop all cerebral blood vessels.
Detailed explanation-4: -Astrocytes form the bridge that connects neuronal signaling to the CNS vasculature.
