"Lobular" refers to a structure that is divided into lobes or lobules, which are small, rounded sections. This term is commonly used in biology and medicine to describe organs or tissues that have a lobe-like appearance, such as the lungs, liver, or breasts. Each lobe can have distinct functions or characteristics, contributing to the overall operation of the organ. In the context of medical conditions, "lobular" can describe certain types of diseases or abnormalities. For example, lobular pneumonia is an infection that affects specific lobes of the lungs, while lobular carcinoma refers to a type of breast cancer that originates in the lobules. Understanding lobular structures helps in diagnosing and treating various health issues.
