The peripheral part of the diaphragm (the peripheral muscular part) The muscular fibers of the diaphragm converge radially to a C-shaped central tendon, which has no bony attachments. The central part of the diaphragm (the central aponeurotic part) The diaphragm is innervated by the _ NERVE.Ĭentral aponeurotic (flat layer of tendon)part and peripheral muscular part Dome descends/contracts with inspiration and ascends/relaxes with expiration. Relaxes, causing the vertical dimensions of the thoracic cavity to narrow.Ī muscle that extends across the bottom of the rib cage, It separates the thoracic cavity from the abdominal cavity. Therefore, you need to equalize pressure by adding more air molecules to the expanded thoracic cavity.ĭuring inhalation (inspiration), the diaphragm _.Ĭontracts, causing the vertical dimensions of the thoracic cavity to increase.ĭuring exhalation (expiration), the diaphragm _. When you expand the thoracic cavity, the pressure decreases because the same number of air molecules are now occupying a larger space.
