Foreign body For other uses of this term, see foreign body (disambiguation) . A foreign body or sometimes known as FB (Latin: corpus alienum) is any object originating outside the body. In machinery, it can mean any unwanted intruding object. Most references to foreign bodies involve propulsion through natural orifices into hollow organs. Foreign bodies can be inert or irritating. If they irritate they will cause inflammation and scarring. They can bring infection into the body or acquire infectious agents and protect them from the body's immune defenses. They can obstruct passageways either by their size or by the scarring they cause.

What are Barr bodies? A Barr body (named after discoverer Murray Barr) is the inactive X chromosome in a female somatic cell, rendered inactive in a process called lyonization, in those species in which sex is determined by the presence of the Y (including humans) or W chromosome rather than the diploidy of the X or Z. typical human female has only one Barr body per somatic cell, while a typical human male has none. Mammalian X-chromosome inactivation is initiated from the X inactivation centre or Xic, usually found near the centromere.
