Question 13

functional activities of the trapezius

Answer 13

steadies scapula and clavicle- against gravity e.g. when vacuuming

provides fixation- controls head position e.g. reading

provides lateral rotation of scapula e.g. putting on coat

produces depression of scapula against resistance- e.g. pushing hands on chair to stand from sitting
