WebAug 1, 2024 · The diaphragm is innervated by the ipsilateral phrenic nerve that arises from the cervical nerve roots of C3-C5. The phrenic nerve emerges through the anterior scalene muscle on either side of the neck and courses posteriorly to the subclavian vein. Both phrenic nerves enter into the thoracic cavity through the thoracic aperture.
The thoracic diaphragm, or simply the diaphragm (Ancient Greek: διάφραγμα, romanized: diáphragma, lit. 'partition'), is a sheet of internal skeletal muscle in humans and other mammals that extends across the bottom of the thoracic cavity.
