Nervous System and Senses Overview

In this video, Paul AR introduces the concept of the five senses: sight, hearing, taste, touch, and smell. Each sense is associated with a specific organ that gathers information and sends it to the brain via the nervous system. The video explains the role of receptor cells and nerve endings in sensing different stimuli. It concludes with a review and interactive questions to reinforce learning.
