Cajal's Appearance of Neuroglia

Cajal's "Appearance of Neuroglia" describes the discovery and detailed observation of neuroglia, the supportive cells in the nervous system. These cells provide structural support, insulation, and nourishment to neurons, which are the primary nerve cells involved in transmitting signals. Cajal's work highlighted how neuroglia differ from neurons in their structure and function, emphasizing their important role in maintaining healthy brain and spinal cord tissue. His detailed illustrations helped scientists better understand the complexity and significance of these supportive cells in nervous system health and function.
