The innermost intercostal muscle is a layer of intercostal muscles deep to the plane that contains the intercostal nerves and intercostal vessels and the internal intercostal muscles. These are divided into:
- transversus thoracis anteriorly
- lateral muscle slips laterally (which cross a single intercostal space)
- subcostalis posteriorly (which often cross more than one intercostal space)

Famous quotes containing the word innermost:
“One receives as reward for much ennui, despondency, boredom—such as a solitude without friends, books, duties, passions must bring with it—those quarter-hours of profoundest contemplation within oneself and nature. He who completely entrenches himself against boredom also entrenches himself against himself: he will never get to drink the strongest refreshing draught from his own innermost fountain.”
—Friedrich Nietzsche (1844–1900)
