94
Q

What is fascia?

A

thin sheath of fibrous tissue, that is loose but strong, which provides support and some protection—encloses muscle or organ

95
Q

How does fascia work?

A

Arranged in continuous “lines” through an entire muscle group, allowing force to be generated through an entire group
