nerve ending

Increased pressure from redistribution of fluid in the nose inhibits nerve endings in nasal passages, reducing the ability to smell and taste — one reason why wasabi and hot sauce are popular condiments on the ISS.

"Our findings show that any substances released from EECs must act via diffusion onto vagal sensory nerve endings in the colon, which then relay sensory information to the brain," says Professor Spencer.

The stomach stretches when we eat a meal, stimulating nerve endings in the organ’s wall that send messages to the brain.

Due to our body’s nerve endings, a heart attack can radiate into the abdomen, neck or shoulder.

As with a bad cold, the process inhibits nerve endings in the nasal passages, meaning you can’t smell or taste very well.
