Which term refers to a protrusion of an internal organ through a weakness in the body wall?

• A. Hernia
• B. Prolapse
• C. Rupture
• D. Laceration

Answer: (A)

A hernia is a protrusion of an internal organ through a weakness or defect in the body wall. This happens when tissue pushes through a gap in the muscle or fascia that normally contains it, creating a noticeable bulge often in the abdominal or groin area. The key idea is that the organ is passing through the wall itself, not just shifting position inside a cavity. This differs from prolapse, which is the downward displacement of an organ while remaining within its normal confines (for example, pelvic organs moving downward within the vaginal canal or rectum), rather than breaking through a wall. It also differs from rupture, which is a tear or breaking of tissue—often due to trauma or disease—without the tissue necessarily protruding through an external opening. Laceration is a cut or tearing of tissue from injury. In practice, you might see or feel a lump that enlarges with coughing or straining and may be reducible to the inside if gentle pressure is applied; however, if the lump becomes painful, discolored, or cannot be pushed back, it can indicate incarceration or strangulation and requires urgent medical attention.
