The name of the structure indicated by the line in the diagram is: _____.

There are two types of neuroglia that produce myelin sheaths: oligodendrocytes and Schwann cells (neurolemmocytes).

Select the best description of astrocytes:

The afferent (sensory) portion of the autonomic nervous system carries sensory information from the viscera to the central nervous system.
