Here are the 15 Standard Surface Mount Terminal Lead Forms represented in the IPC-7351 and IPC-7352. 

The first bend in the lead is referred to as the Knee. The second bend is the Heel and the end of the lead is the Toe. 

For Grid Array and BTC leads, the solder joint goal is a Periphery.

The anatomy of the human leg is used to determine the Surface Mount Toe and Heel of the solder joint definition.
