From Pathfinder Wiki
A window opening must have a weight-bearing header. The header is a pair of 2x4's which are turned on their edges and nailed to a stud. A pair of studs (called jack studs) run from the bottom of the header to the floor to help support the weight. Short studs (called cripple studs then run from the header to the top plate. The cripple studs supply a support for the wall's sheeting.
