The innermost intercostal muscle is a layer of intercostal muscles.[1] It may also be called the intima of the internal intercostal muscles.[2] It is the deepest muscular layer of the thorax,[3] with muscle fibres running vertically (in parallel with the internal intercostal muscles).[2] It is present only in the middle of each intercostal space, and often not present higher up the rib cage.[3] It lies deep to the plane that contains the intercostal nerves and intercostal vessels, and the internal intercostal muscles.[3][4] The diaphragm is continuous with the innermost intercostal muscle.[5]
