The cup-shaped socket of the hip joint. The acetabulum is a feature of the pelvis. The head (upper end) of the femur (thighbone) fits into the acetabulum and articulates with it, forming a ball-and-socket joint.

A ring of fibrocartilage (fibrous cartilage) that runs around the acetabulum (cup) of the hip joint and increases its depth. The head of the femur (the bone in the thigh) fits in the acetabulum. The labrum deepens this cavity and effectively increases the surface (and strength) of the hip joint. Injuries to the acetabular labrum can occur…

Pertaining to the acetabulum, the cup-shaped socket of the hip joint which is a key feature of the pelvis. The head (upper end) of the femur (the thighbone) fits into the acetabulum and articulates with it, forming a ball-and-socket joint. The acetabulum is not just cup-shaped. The word “acetabulum” in Latin means cup, a vinegar cup.

A genetic disorder in which there is absence of the protein ceruloplasmin from blood and accumulation of iron in the pancreas, liver and brain, causing diabetes and progressive neurodegeneration with the tremors and gait abnormalities characteristic of Parkinson disease. Ceruloplasmin normally removes iron from cells. The absence of ceruloplasmin leads to the abnormal deposition of iron in cells, including those of the pancreas, liver,…

A fragment of a chromosome (one of the microscopically visible carriers of the genetic material DNA) that is lacking a centromere (the “waist” of the chromosome essential for the division and the retention of the chromosome in the cell) and so is lost when the cell divides.

A vaccine that may contain cellular material but does not contain complete cells.

Not made up of cells or divided into cells. Or lacking intact cells as, for example, an acellular vaccine which may contain cellular material but not complete cells.

ACE inhibitor.

An essential regulator of heart function. Also may be involved in the embryonic development of the heart. The ACE2 gene has been mapped to the X chromosome (band Xp22).
