The umbilical region is a specific area of the abdomen surrounding the belly button. Synonyms for this anatomical region include the umbilicus, the navel, and the belly button area. Other terms that may be used to refer to the umbilical region include the epigastric region (located above the belly button), the hypogastric region (located below the belly button), and the central abdominal region (located in the center of the abdomen). It is important to note that medical professionals and anatomists may use different terminology to describe specific areas of the body, but these terms generally refer to the same general location or region.
