What anchors and braces neurons with cellular projections?

Anchoring and bracing neurons with cellular projections are primarily facilitated by glial cells, particularly astrocytes. These supportive cells provide structural support, help maintain the extracellular environment, and form connections with neurons through their end-feet that wrap around synapses and blood vessels. Additionally, the extracellular matrix (ECM) plays a crucial role by providing biochemical cues and physical support that guide neuronal growth and connectivity. Together, these elements ensure proper neuronal function and stability within the nervous system.
