Notes on Meaning

• The core concept is the protrusion of a structure through a containing wall. While the reference context mentions "rupture in smooth muscle," herniation can occur through other tissues, such as fibrous cartilage (in spinal discs) or connective tissue. The defining feature is the escape from a normal compartment.
