navel, umbilicus; Omphal‑ refers to the umbilicus, the scar on the abdomen where the umbilical cord attached during fetal life. In pediatrics and surgery, it builds terms for birth defects like omphalocele (umbilical hernia with organs protruding in a sac) and infections like omphalitis (neonatal umbilical inflammation). Surgical terms include omphalotomy (cutting the umbilical cord) and omphalectomy (navel excision).
greekomphalos; From Ancient Greek ὀμφαλός (omphalós) meaning “navel, belly‑button,” considered the “central point” (as in the mythic Omphalos stone at Delphi, “navel of the earth”). Cognate with Latin umbilicus (giving umbilic‑/omphal‑ parallels)
