After the headstock and neck comes the body. Here you will see more differences between an acoustic and electric guitar.
On both guitars you will find pick guards and bridges. The pick guard protects the top of the guitar from damage when a pick (or plectrum) is used (more about the pick later). The strings pass over a bridge before they are secured to the guitar, either through the use of push-pins on an acoustic guitar, or a series of hitch pins and loop-ends on an electric. The bridge determines the length of each string (from the nut to the bridge) and if you look at it closely, you will see that it is not straight across, but angled. This is because some strings need to be a little longer than others to play in tune.
