• \An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Structure of striated muscle and/or smooth muscle\Structure of striated muscle\Skeletal muscle structure\Skeletal muscle part\Part of diaphragm\Aperture of diaphragm\Lesser aperture of diaphragm
