SMELL
HOW DOES IT WORK?

Your sense of smell is an amazing thing.
Molecules enter your nose from air and go to
receptor neurons. Small hairs called cilia capture
the molecules and identify them.

The sense of smell is very useful to daily bases. It
helps us taste and can warn us of danger like
when there’s smoke or poison, it can also helps us
in survival.
 Its also fun to have!

TOUCH

It works by sending information to the spinal
cord then goes to the brain. The sense of touch is
located in the dermis part of the skin and is
found everywhere on your body.

The sense of touch is one of the important. It’s
the only sense that is all over your body and not
just a specific part. You use it for working, feeling
and everything else.

tell you not because it hot. (Just an example)
Your brain controls the sense of touch.

TASTE
