A century and a half after first being described, glia are beginning to reveal their intricate and important roles in nervous system development and function. Recent studies in the nematode Caenorhabditis elegans suggest that this invertebrate will provide important insight into these roles. Studies of C. elegans have revealed a connection between glial ensheathment of neurons and tubulogenesis, have uncovered glial roles in neurite growth, navigation, and function, and have demonstrated roles for glia and glia-like cells in synapse formation and function. Given the conservation of basic anatomical, functional and molecular features of the nervous systems between C. elegans and vertebrates, these recent advances are likely to be informative in describing nervous system assembly and function in all organisms possessing a nervous system.
