#TikTokAwards Anatomy of the Human Leg with all its Systems ✨ . . The human leg consists of several key systems and components: Skeletal System Femur: Thigh bone, the longest in the body. Patella: Kneecap, protects the knee joint. Tibia: Shin bone, larger and weight-bearing. Fibula: Smaller bone alongside the tibia. Tarsals: Seven ankle bones. Metatarsals: Five foot bones. Phalanges: Toe bones. Muscular System Quadriceps: Four muscles extending the knee. Hamstrings: Three muscles flexing the knee. Gastrocnemius: Calf muscle aiding plantar flexion. Soleus: Assists in plantar flexion, under the gastrocnemius. Tibialis Anterior: Responsible for foot dorsiflexion. Nervous System Sciatic Nerve: Largest nerve, runs from lower back to legs. Femoral Nerve: Innervates the quadriceps and thigh skin. Tibial and Common Peroneal Nerves: Innervate the lower leg and foot. Circulatory System Femoral Artery: Main blood supply to the thigh. Popliteal Artery: Continuation behind the knee. Tibial Arteries: Supply the lower leg. Veins: Include the great saphenous vein and deep veins. Lymphatic System Lymph nodes in the groin and popliteal areas filter lymph fluid. Integumentary System Skin: Protects the leg, contains hair follicles and glands. Subcutaneous Tissue: Provides insulation and cushioning. Articular System Knee Joint: Allows flexion and extension. Ankle Joint: Allows dorsiflexion and plantar flexion. Summary: The human leg is a complex structure of multiple systems that enable movement, support, and various functions, with each component playing a vital role in mobility. . . . #humanleg #anatomy #skeletalsystem #muscularsystem #nervoussystem #circulatorysystem #lymphaticsystem #femur #patella #fibula #tarsals #quadriceps #hamstrings #tibia #anatomi #anatomia #anatomía #Rectum #pregnancy - @smart.doctor
