alaraajoihin

Alaraajoihin is Finnish for the lower limbs, the paired appendages of the lower part of the human body. The region extends from the hips to the toes and includes the thigh, knee, lower leg, ankle, and foot. The major bones are the femur in the thigh; the patella, tibia and fibula in the leg; and the tarsals, metatarsals, and phalanges of the foot.

The joints include the hip, knee, and ankle, which support standing and locomotion. The limbs house muscles organized into compartments: anterior (extensors and dorsiflexors), posterior (flexors and plantar flexors), and lateral compartments. Together with ligaments and tendons they enable movement and stability.

Circulation and nerves: the main arterial supply comes from the femoral artery, continuing as the popliteal and tibial arteries, while the venous system includes deep and superficial veins. Innervation is provided by the femoral nerve to the anterior thigh and by the sciatic nerve (splitting into tibial and common fibular nerves) for the posterior and lower leg.

Clinical relevance: injuries and conditions affecting alaraajoihin include fractures, ligament and meniscal injuries of the knee, ankle sprains, and disorders such as peripheral arterial disease, venous insufficiency, and neuropathies. Treatment ranges from rest and rehabilitation to surgical intervention depending on the condition.
