Question

Quizplus · Accepted Answer

The scalene muscles are responsible for lifting the upper chest particularly during times of high ventilatory demand, such as during exercise or when there is increased respiratory effort required. While they do play a role in stabilizing the upper seven ribs, this is not their primary function. They do not support the trachea within the thorax during heavy exercise, and while they can activate if intrathoracic pressure falls, this is not their most important ventilatory function.
