28347008: External ear structure (body structure)

SNOMED CT Concept\Body structure (body structure)\Anatomical or acquired body structure (body structure)\Anatomical structure\...

\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 sensory organ\Ear structure\Ear part\External ear structure
