The term front leg when describing an animal's anatomy can be substituted with several synonyms depending on the species and context. In horses, the front leg is often referred to as the forelimb or simply the front limb. For dogs, the front leg is known as the foreleg or anterior limb. Other synonyms include arm, forequarter, and shoulder for larger animals such as cattle and elephants. The term appendage is also a broad term used for any extremity of the body. However, in scientific contexts, anatomical terminology such as brachium or manus is used to describe the front legs of mammals. Overall, the choice of synonym depends on the specific animal and the level of detail required in the description.
