Anatomy of Lower Limb Bones

Femur (thigh bone): longest and strongest bone in the body, connects hip joint to knee joint
Patella (kneecap): triangular bone that sits at the front of the knee joint
Tibia (shin bone): larger of the two bones in the lower leg, connects knee joint to ankle joint
Fibula: smaller of the two bones in the lower leg, connects knee joint to ankle joint
Tarsal bones: 7 bones in the ankle, forming the hindfoot and midfoot
Metatarsal bones: 5 bones in the foot, connecting the tarsal bones to the phalanges
Phalanges: 14 bones in the toes, 2 in the great toe and 3 in each of the other toes

Hip joint: ball-and-socket joint between the femur and pelvis
Knee joint: hinge joint between the femur and tibia
Ankle joint: hinge joint between the tibia and fibula and the tarsal bones
Subtalar joint: joint between the talus and calcaneus bones in the ankle
Metatarsophalangeal joints: joints between the metatarsal bones and phalanges in the toes
Interphalangeal joints: joints between the phalanges in the toes

Gluteal muscles: group of muscles in the buttocks, including gluteus maximus, gluteus medius, and gluteus minimus
Hamstring muscles: group of muscles in the back of the thigh, including biceps femoris, semitendinosus, and semimembranosus
Quadriceps muscles: group of muscles in the front of the thigh, including rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius
Calf muscles: group of muscles in the lower leg, including gastrocnemius and soleus
Intrinsic foot muscles: group of muscles in the foot, including flexor digitorum brevis and extensor digitorum brevis

Femoral artery: main artery of the lower limb, supplying the thigh and knee
Popliteal artery: artery that supplies the knee and lower leg
Tibial artery: artery that supplies the lower leg and foot
Fibular artery: artery that supplies the lower leg and foot
Sciatic nerve: nerve that supplies the lower limb, including the thigh, knee, and lower leg
Tibial nerve: nerve that supplies the lower leg and foot
Fibular nerve: nerve that supplies the lower leg and foot

Longest and strongest bone in the body is the femur, which connects the hip joint to the knee joint
Patella is a triangular bone that sits at the front of the knee joint
Larger bone in the lower leg is the tibia, which connects the knee joint to the ankle joint
Fibula is the smaller bone in the lower leg, connecting the knee joint to the ankle joint
7 bones in the ankle form the hindfoot and midfoot, known as the tarsal bones
5 bones in the foot connect the tarsal bones to the phalanges, known as the metatarsal bones
14 bones in the toes, with 2 in the great toe and 3 in each of the other toes, are called phalanges

Hip joint is a ball-and-socket joint between the femur and pelvis
Knee joint is a hinge joint between the femur and tibia
Ankle joint is a hinge joint between the tibia and fibula and the tarsal bones
Subtalar joint is a joint between the talus and calcaneus bones in the ankle
Joints between the metatarsal bones and phalanges in the toes are called metatarsophalangeal joints
Joints between the phalanges in the toes are called interphalangeal joints

Gluteal muscles include gluteus maximus, gluteus medius, and gluteus minimus, and are located in the buttocks
Hamstring muscles include biceps femoris, semitendinosus, and semimembranosus, and are located in the back of the thigh
