You smell with your body, not just your nose

Jennifer Pluznick and her lab at the Johns Hopkins School of Medicine research the role of the body's olfactory signaling system. While we generally think of olfactory receptors as being found in the nose, they are actually found all throughout the body-from our muscles to our blood vessels. Watch Jennifer's 2016 TEDMED Talk to learn how studying the full body olfactory system has the potential to inform our understanding of important bodily processes and human physiology.
