Question

What do hands, face, eyes, and body have to do with communicating in ASL?

Answer 1

"In sign language, facial expressions are used to express both linguistic information and emotions. For example: eyebrow raise is necessary to mark general questions in most sign languages. At the same time, signers use the face to express emotions – either their own, or when quoting someone else.

Answer 2

Facial expressions are an essential part of ASL communication. These facial expressions enhance the meaning of specific signs, increasing the emotion expressed. They are part of the non-manual markers that influence the signs' meaning.
