Ventricolumna is a technical term in anatomy, referring to the line dividing the anterior and posterior horns of the lateral ventricle of the brain. It is spelled as follows: /vɛn.tri.kəˈlʌm.nə/ - using the International Phonetic Alphabet (IPA). The beginning "ventri-" comes from the Latin word for "belly," while "columna" means "column" or "pillar." Thus, the term ventricolumna describes the shape and location of this anatomical feature, which resembles a column or pillar dividing the ventricles.
