The deep fascia forms a single continual membrane which envelopes and connects all tissues in the body.
It not only surrounds muscle as a whole but also every part within it, right down to the individual fibres and fibrils.
And it continues beyond the muscle to form the tendon, becomes the periosteum where it reaches the bone and the capsule and the ligaments at the joint.
Massage strokes help loosening the fascial bonds between the fascial layers and rehydrating the fascia.
