In anatomy, the elastic layer or elastic lamina, a sheet of elastic tissue found in the walls of blood vessels and other tubular structures, helping them stretch and recoil.
From Latin 'elastica,' the feminine form of 'elasticus' (elastic), used directly in anatomical terminology as the scientific name for elastic tissue layers.
Your blood vessels have several layers, and the elastica is the stretchy middle layer that expands when your heart pumps and snaps back between beats—without it, your arteries would either explode or collapse!
