Nervous System and Diagnostic Tools

The video tutorial covers chapter 15 on the nervous system, detailing its two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, while the PNS encompasses cranial and spinal nerves. The tutorial explains the roles of neurons and neuroglia, introduces medical terminology related to the nervous system, and discusses common diseases and disorders such as strokes and spinal cord injuries. Diagnostic tests like EEGs and MRIs are also covered, concluding with a summary of the chapter.
