Nervous System Functions and Structures

The video tutorial introduces the nervous system, explaining its role in processing signals from sense organs. It covers the central and peripheral nervous systems, detailing the brain's parts and their functions. The structure of neurons and their role in signal transmission is discussed. Tips for maintaining a healthy nervous system are provided, and viewers are encouraged to engage with the content through quizzes and social media.
