A discrete bulging or local rupture in the basal lamina which allows a cell process to cross to the “wrong†side of a tissue border. The same term might be used to describe a discrete bulging in any other thin membrane or tissue. See Basal lamina See Fenestration
In neurology, used to describe the movement of brain tissue through or across small openings due to increased intracranial pressure.
Any abnormal bulge of a body part may be referred to as a hernia and the process of bulging is called herniation.
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.
