Tendons
Bands of fibrous tissue that attach the muscle to the bones, allowing bones to move
Ligaments
Dense strong bands of fibrous tissue that connects bones to each other
Scalp and face muscles
Muscles affected by massage are manipulated from insertion attachment to origin attachment
Light facial massage should follow muscle line

Arteries
