Medullary

Medullary (from Latin medulla - brain), brain-like. Tissues are called medullary that have a soft consistency, a homogeneous appearance, a shiny bulging surface on cross-section, and resemble brain substance in this respect, regardless of color. The term is used to denote soft, easily disintegrating cancerous tumors (carcinoma medullare), as well as to characterize the tissue of lymph glands during their acute inflammation. In normal anatomy, the medullary substance refers to the central parts of certain organs (kidneys, adrenal glands), which are softer than the cortical substance, for example, the medullary substance (substantia medullaris), medullary layer, medullary stria (stria medullaris), etc.
