Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] JOAN CARTAN-HANSEN, Host: Humans understand the world through five main senses: Sight, hearing, smell, taste and touch.
Sight or vision is thought to be our most important sense.
We recognize 80 percent of our impressions of the world through our eyes.
Our sense of smell improves when we're hungry but it gets worse as we age.
Smell is also tied to our memories and the brain's limbic system.
That's why a smell can spark a memory.
The largest organ in your body is your skin.
Most of the receptors in our skin send information directly to the brain.
But one set of touch receptors do not.
When receptors called reflexes are touched, the associated muscles act immediately and then send data to the brain.
Speaking of sending data to the brain, the hearing system is the fastest, sending a signal in just three milliseconds.
Smell and taste are the slowest.
It can take more than a second for the brain to react to a new smell or taste sensation.
For more information about the five senses, check out the Science Trek website.
