bones of the lower limb.

The lower bones are a versatile group. They range from weird shapes, the long bones of the thigh and calf regions to the small bones that put the foot together. All together they make up a group that can withstand weight and the actions like walking and running.

Hip bone!

The hip bone forms the skeleton in the region of the hips and butt. Its irregular bone made up of three parts:

· Ilium – upper part of the bone. Spread out and looks like a fan.

· Ischium – thick and strong part of the bone in the butt region.

· Pubis – part that makes up the front of the pelvic region.

All three parts meet at acetabulum, a cup shaped depression which the head of the though bone fits neatly to from the hip joint. The right and left hip bones connect with the sacrum and coccyx in the lower part of the vertebral to complete the skeleton of the pelvis.

Femur – The thigh bone!

The femur is the strongest of the long bones in the body and is the only bone in the thigh region. Its uppermost part is shapes like a well rounded head that sits in the acetabulum of the hip bone to from the hip joint. A thin neck connects the head with the shaft of the bone and is often the site of fracture to old people. The lower part of the femur is flatter and spreads out and forms part of the knee joint. The thick shaft of the femur is at the core of the thigh and is surrounded and protected by strong muscles such as the hamstrings and quadriceps.

Patella – the knee cap!

The knee cap is the prominent part of the front of the knee, but it is actually form by a totally separate bone called the patella. The patella is a sesamoid bone as it lies within the tendon of the muscle quadriceps femoris, a powerful muscle in front of the thigh. When the lower limb is stretched out the petal can be felt and even be flet by grabbing the side and move it side to side.

Tibia and Fibula – bones of the leg!

Your leg is actually the part between your knee and ankle joints! These are the two long bones in the leg, the tibia is longer and stouter. The end of the tibia is part of the knee joint. Much of the tibia forms our shins where if you’re kicked can be felt. The fibula lies just behind the tibia, it doesn’t reach all the way up to the knee, buts the other end along with the lower part of the tibia form the ankle joint. You can feel the bones on either side of the ankle.

Bones of the foot!

The foot is made of tiny different bones – the tarsal bones, metatarsal bones and phalanges. The tarsal bones are located in the region of the ankle and heel. They’re arranged in two rows, the first row is two bones, the talus and the calcaneus. The talus, placed above the calcaneus, connects with the lower part of the tibia and fibula in the ankle joint. The heel is formed by the calcaneus. The second row is in front of the first, has one cuboid and three cuneiform bones that are arranged side by side. These bones are connected with five metatarsal bones which are in front of them. They turn in and connect with the phalanges, your toe bones. While the great two has toe, (maybe your big toe..?), and all the other toes have three each.

The bones of the lower limb are adapted to withstand weight from everyday use like walking or running.
