Below are four distinct Myofascial meridians that run from the axial skeleton through four different planes in the shoulder, along all sides of the arm and to the hand out to the thumb, little finger, palm and back of the hand.
The arm lines have more cross-over structures than there are in the legs. So even if this describes longitudinal structures, they are bound together transversely as well. This is because human arms are built to have high mobility compared to the legs that offer more stability. To cope with this free movement more varied lines and support in all directions is required.
The arm lines is quite logically arranged with a deep and a shallow line on the front of the arm, as well as a deep and shallow one on the back of arm. The arm lines are named after their location where they cross the shoulder. All arm lines goes unnoticed into all other lines and performs pushing, pulling, rotations, anvils and infinite movements in collaboration with the eyes in order to perform all the advanced movements we do with our arms and hands.
