Breathing
-
Muscle Name: Diaphragm muscle
Action: Contraction causes flattening and increases vertical dimension of thoracic cavity, (inhalation), and relaxation causes movement superiorly and decreases vertical dimension of thoracic cavity (exhalation)
Innervation: Phrenic nerve that contains axons from cervical spinal nerves (C3 to C5)
-
Muscle Name: External Intercostals muscle
Action: Contraction elevates the ribs and increases anteroposterior and lateral dimensions of thoracic cavity (inhalation), and relaxation depresses ribs and decreases anteroposterior and lateral dimensions of thoracic cavity (exhalation)

-
Muscle Name: Internal Intercostals muscle
Action: Contraction draws adjacent ribs together to further decrease anteroposterior and lateral dimensions of thoracic cavity during forced exhalation
