Bacak

Bacak is a Turkish noun meaning leg, the limb that extends from the hip to the ankle in humans and many four-legged animals. In everyday Turkish, bacak refers to the entire lower-extremity, while more specific terms such as uyluk (thigh) and baldır (calf) denote its subsegments. The word is used widely in medical, anatomical, and everyday contexts.

Anatomically, the leg comprises bones, joints, muscles, nerves, and vessels. In humans, the thigh contains the femur, the upper leg bone; the lower leg contains the tibia and fibula; the knee connects thigh and lower leg, and the patella (kneecap) sits within the knee joint. The major muscle groups include the quadriceps in the front of the thigh, the hamstrings at the back, and the calf muscles such as the gastrocnemius and soleus. The femoral artery and nerve run through the thigh, while the popliteal vessels and sciatic nerve are key structures behind the knee and lower leg.

Common clinical and athletic concerns involve injuries to the leg, including fractures of the femur or tibia/fibula, knee ligament injuries, muscle strains, and shin splints. Treatment and rehabilitation depend on the specific structure injured and may require immobilization, surgery, or physical therapy.

In Turkish usage, bacak appears in many expressions related to movement, fitness, and everyday activities and is a core term in medical, sports, and anatomical vocabulary. The term is primarily used in Turkish-speaking regions and communities.
