The Diaphragm Receives Help from the ________ Muscles in the Activity

Question

The diaphragm receives help from the ________ muscles in the activity of breathing.
A)Pleural
B)Thoracic
C)Accessory
D)Respiratory

Accepted Answer

The accessory muscles, including the intercostal muscles and muscles in the neck and back, help the diaphragm in the activity of breathing. The pleural and respiratory muscles are not directly involved in assisting the diaphragm. While the thoracic muscles are involved in breathing, the term is not specific enough to be the best answer.
