Triceps surae, also known as the calf muscle, is a group of muscles located at the back of the lower leg. This term is derived from the Latin word "triceps," meaning three heads, and "surae," meaning the calf of the leg. Some synonyms for triceps surae include calf muscles, gastrocnemius, soleus, plantaris, and popliteus. These muscles play a crucial role in movements such as running, jumping, and walking. Strengthening the triceps surae muscles can help prevent injuries and improve overall athletic performance. Incorporating exercises such as calf raises and heel drops can target and strengthen these important muscles.
