Five Senses
We notice the world with five sense organs: eyes, ears, nose, tongue, and skin. Eyes see color and shape, ears hear sound, the nose smells, and the tongue tastes. Skin feels warm and cold, smooth and rough. Pick one sense with the slider and look at the path drawn from that organ to the brain.
All five senses sit together because noticing the world is never just one organ's job. You can look at a piece of fruit, smell it, take a bite, and feel the skin with your hand, and those signals meet in the brain as one experience. Memorizing each organ on its own does not help much when a scene uses more than one sense at once. With the five together, the question is which one is working first. If we had no senses at all, there would be no way to notice what is happening around us.
The brain is drawn in the middle, and the eye, ear, nose, tongue, and skin sit around it. When you pick a sense with the slider, that organ looks brighter, a solid line runs to the brain, and three dots sit on the line. The other four stay faded, and their lines stay dashed. Those dots mark the path of the signal; they do not travel across the screen. Change the sense and a different path lights up, so you only need to see which route is on.
When your nose is stuffed, even food you like can taste dull. The tongue is not broken. It only sorts a few basic tastes, sweet, salty, sour, and bitter, and smell is how you tell one food from another. Flower and food smells come in through the nose, and that is often what makes you hungry. The feeling we call taste is made by the tongue and the nose together.
The organs that sense the outside world all live in the body. Meaning is attached to those signals in the brain, and that brain sits in the same body as the inner organs you will meet next. If you first see how a sense connects to the brain, it is easier to place what each inner organ does later. Knowing a fruit is a fruit happens on that same inside connection.
When you work an example, look at the feeling first, seeing, hearing, smell, taste, or touch, before you name the organ. Once the feeling is clear, the organ's name follows. Several senses can overlap in one scene, so the job is to pick only the feeling the question asks about. After you choose, you can check whether that organ's path to the brain lights up in the picture.
