Upper trapezius
Pars descendens musculi trapezii · Horní část trapézového svalu
Muscles
Looks like
The upper part of the kite-shaped back muscle, running from the skull base over the top of each shoulder.
What it does
Lifts and shrugs the shoulders and supports the neck.
Keeping it well
Tension and trigger points with desk work and stress; movement, breaks and strength work help more than rest.
