Pars transversa musculi trapezii · Příčná část trapézového svalu
Muscles
Looks like
The middle band of the trapezius, running across from the upper chest spines to the shoulder blade spine and acromion.
What it does
Pulls the shoulder blades back toward the spine.
Keeping it well
Rows and face pulls strengthen it. Damage to the accessory nerve in neck surgery causes a drooping shoulder.
