Understanding the Human Sensory System

The video provides an in-depth exploration of the human sensory systems, including the visual, auditory, tactile, gustatory, and olfactory systems. It explains the structure and function of each sensory organ, such as the eye, ear, skin, tongue, and nose, and how they process different stimuli. The video also includes practice questions to reinforce learning.
