The ability of neurons to form and modulate precise connections with one another is critical to every aspect of nervous system development and function. Adding to the complexity of the nervous system, glial cells (astrocytes, oligodendrocytes, microglia, and others) far outnumber neurons, and their contributions to critical brain functions are increasingly being appreciated. Malformation or dysfunction of even just a small subset of cells can manifest in neurologic symptoms. Understanding the essentials of the nervous system’s anatomy and function provides a robust basis for neurologic practice. Examining a patient who presents with a neurologic problem should lead the clinician to ask and answer 2 fundamental questions: SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/10/05 UR - accesspediatrics.mhmedical.com/content.aspx?aid=1182922018 ER -
