**Tibial flexor (lat. flexor cruris longus)** - muscle tissue of the upper part of the human leg, starts from the upper surface of the tibia and fibula and is attached to the base of the I and II bones of the foot. Function: participates in maintaining body balance while standing and in extending the first toe.\n\nOther names are: popliteal flexor (aponeurosis retinaculitis). The part of the Achilles tendon (if not sutured) is called a. tenoniosseosis crurum longi.\n\nFlexors are muscle fibers that run along the outside of the legs from the knees and below and are responsible for the movement of the leg at the knee and foot. These muscles are responsible for flexing the muscles at the knee. They also help in balancing the foot while moving. Flexion occurs when the muscles contract and pull the ligamentous tissue down toward the knee. When the ligaments are aligned in this direction, the knee can become flexible for movement. There are two main flexors: \n- flexor tibia - This muscle (from the Latin flexor wall) connects to the knee and the bone of the lateral or lateral malleolus and is responsible for stabilizing the knee joint. It also retracts the joint and prevents it from bending, keeping the leg stable when walking or running. \n- Hip Flexor - This is the muscle located between the femur (patella) and the thigh that flexes the hip and maintains knee stability while walking or running. It also plays an important role in controlling the speed and strength of movements, allowing you to maintain balance and control the coordination of movements. \n\nThese muscles work together to help you
