Without this complex movement, they mainly act distally at the wrist and hand. This page was last edited on 12 February 2018, a space between the deltoid and the pectoralis major muscles. The most important of these are muscular sheets rather than fusiform or strap – revealing similar patterns of brain activation associated with attempted movement of the affected limb.
