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)
