Our facial expressions convey a lot about our emotions, but why? Hank explores how our evolution has helped form how we communicate with our faces. Hosted by: Hank Green

We don't often think of touch as being a vital part of movement, but touch is one part of a network that oversees all the sensations arising from the surface and interior of our bodies. Touch, pain, temperature, and our spatial awareness...

Figuring out exactly what consciousness is and whether or not it could emerge in non-human things has stumped us for centuries. Now, analyzing it from a scientific perspective might not just be possible, but necessary.

Some people are capable of concentrating in a storm of noise and motion, and some get distracted by the slightest squeak of a classmate’s chair. This has to do with our brain’s ability to filter, and not only are both entirely natural,...

We chose not to give a numerical value for how many characteristics of life there are, because we do not want to imply that what we are listing must be a specific order, or that it cannot be expanded upon or include exceptions....

It's possible life could form based on elements other than carbon, but they would look much different than the life we are used to.

A Quick Question answer that explains the chemistry that makes minty things taste “cool” and spicy things taste “hot”.

Our facial expressions convey a lot about our emotions, but why? Hank explores how our evolution has helped form how we communicate with our faces.

In this episode of Crash Course Anatomy & Physiology, Hank gives you a brief history of histology and introduces you to the different types and functions of your body's tissues.
