There isn't a single scientific name for "leg" as a whole. The term "leg" in anatomy refers to a specific part of a limb, and the scientific names for limbs vary depending on the animal and the specific part of the limb.

For example:

* In humans: The lower limb is divided into the thigh (femur), leg (tibia and fibula), foot, and toes.

* In quadrupeds: The leg is typically considered the entire lower limb, from the hip to the foot.

Therefore, the specific scientific terms for different parts of the "leg" depend on the context and the animal being considered.
