WebMay 14, 2024 · The tips of axons meet other neurons at junctions called synapses, muscles (called neuromuscular junctions) and glands. Glia Glial cells surround neurons. Once thought to be simply support for neurons ( glia = glue), they turn out to serve several important functions. There are three types: Schwann cells. Cell junctions or junctional complexes, are a class of cellular structures consisting of multiprotein complexes that provide contact or adhesion between neighboring cells or between a cell and the extracellular matrix in animals. They also maintain the paracellular barrier of epithelia and control paracellular transport. Cell junctions are especially abundant in epithelial tissues. Combined with cell adhesion molecules and extracellular matrix, cell junctions help hold animal cells together.
