• \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).\Organ part\Skin part\Structure of skin region\Skin structure of trunk\Skin of part of trunk (body structure)\Skin structure of lower trunk\Skin structure of pelvis\Skin of part of pelvic region\Skin structure of perineum (body structure)\Skin structure of anogenital region (body structure)\Skin of part of anogenital region\Skin structure of perianal area\Perianal keratinised hair bearing stratified squamous epithelial skin within a radius of 5 cm from the anal verge.
