rupture in smooth muscle tissue through which a bodily structure protrudes

The bulging through of a part of the body e.g the nucleus pulposus, can herniate through the annulus fibrosus.

(also called herniated disc) The spine's mobile vertebrae are separated by discs, which act as shock absorbers. The disc's outer section, called the annulus, is made of tough, criss-crossed fibrous layers of tissue. The central portion, called the nucleus pulposus, is elastic and changes shape when you bend. Occasionally, the annulus will tear, and a portion of the nucleus will push through the opening, compressing a nearby nerve. This is called a herniation. On rare occasions the herniated portion actually breaks off. In this case, the diagnosis is a disc sequestration.

a breakthrough of a body organ or part of an organ through a tear or part of a membrane, muscle, or other tissue.

(Part of) an organ (or structure) protruding into a neighbouring organ or cavity, or out through membranes or tissues that contain it.

Bulging of tissue through an opening in a membrane, muscle or bone.

The bulging through of a part of the body eg. the nucleus pulposis can be herniated through the annulus fibrosis.

(cerebral) protrusion of the brain through the cranial wall.

A protrusion of an organ or part of an organ through the wall that normally contains it.

Formation of a protrusion.

It is a focal protrusion of disc material beyond the posterior margins of the vertebral endplates. The disc margin has an irregular morphology. The annular layers may be partially or completely torn.

the protrusion or projection of an organ or other body structure through a defect or natural opening in a covering membrane, muscle, or bone.

Herniation is the abnormal protrusion of an organ or other body structure through a defect or opening in a covering, membrane, muscle, or bone.
