Question

Inspiratory muscles are generally _ , whereas expiratory muscles are generally .
A) Above the diaphragm, below the diaphragm
B) Contracted, relaxed
C) Below the diaphragm, above the diaphragm
D) Controlled, reflexive

Accepted Answer

Inspiratory muscles, such as the diaphragm and intercostal muscles, are primarily located below the diaphragm. Expiratory muscles, which include the abdominal muscles and the internal intercostal muscles, are generally found above the diaphragm. This arrangement facilitates the expansion and contraction of the thoracic cavity during breathing.
