Question: 1 / 400

When ribs are depressed, they are typically stuck in what position?

Inhalation

Exhalation

When ribs are depressed, they are typically stuck in an exhalation position. During normal respiration, inhalation involves the elevation of the ribs, which aids in increasing thoracic volume and drawing air into the lungs. Conversely, exhalation is characterized by the depression of the ribs, which decreases thoracic volume and helps expel air from the lungs.

If the ribs are described as being depressed, it indicates they are likely in a state where they have not returned to their neutral position following an exhalation. This can result in a functional restriction of rib motion and may be associated with a variety of clinical conditions. Understanding this concept is key in osteopathic practice, especially in addressing respiratory mechanics and facilitating proper rib motion during treatment.
