Medical Term:

membrane attack complex

 

Definition: a complex of complement components (C5–C9) that, when activated, bind to the membrane of a target cell, penetrating it with a hydrophobic residue exteriorly and a hydrophilic residue in the interior of the cell; this allows passage of ions and water, swelling of the cell and subsequent lysis.
