While custom electric guitar construction has many variations, in terms of the materials used for the body, the shape of the body, and the configuration of the neck, bridge, and pickups, there are features which are found in almost every electric guitar. The basic parts of an electric guitar are usually quite consistant. You usually have a headstock, a neck and truss rod, fretboard and frets, body, 1 or more magnetic pickups, a bridge (fixed or spring loaded), the control knobs and input jack.
