|Ilium
|Ilium
|The ilium forms the sacroiliac joint with the sacrum along its medial side and forms the superior end of the hip joint at the acetabulum. The sacroiliac joint is a planar joint that allows a slight degree of gliding between the pelvis and the spinal column. The hip joint is a ball-and-socket joint that permits the thigh to have a free range of motion.

Parts Function Image
Hip Ilium The ilium forms the sacroiliac joint with the sacrum along its medial side and forms the superior end of the hip joint at the acetabulum. The sacroiliac joint is a planar joint that allows a slight degree of gliding between the pelvis and the spinal column. The hip joint is a ball-and-socket joint that permits the thigh to have a free range of motion.

Ischium Forms the lower and back part of the hip bone.

Pubic Bone The ventral and anterior of the three parts that come together to create the pelvic bone.

Acetabulum A cup-shaped opening on each side of the pelvic girdle formed where the ischium, ilium, and pubis all meet, and into which the head of the femur inserts.

Foramen obturatum The large opening created by the ischium and pubis bones of the pelvis through which nerves and blood vessels pass.
By Je at uwo at English Wikipedia (Transferred from en.wikipedia to Commons.) [Public domain], via Wikimedia Commons
Parts Function Image
Knee Femur Supports the weight of the body and allowing motion of the leg. The femur articulates proximally with the acetabulum of the pelvis forming the hip joint, and distally with the tibia and patella to form the knee joint.
See page for author [Public domain or Public domain], via Wikimedia Commons
Tibia It forms the knee joint with the femur and the ankle joint with the fibula and tarsus.
Henry Vandyke Carter [Public domain], via Wikimedia Commons
Patella The patella increases the leverage that the quadriceps tendon can exert on the femur by increasing the angle at which it acts. Also acts as protection for the muscles underneath the patella.

Parts Function Image
Ankle Fibula Long, thin and lateral bone of the lower leg. It runs parallel to the tibia, or shin bone, and plays a significant role in stabilizing the ankle and supporting the muscles of the lower leg.

Tibula Known as the shinbone and is the second largest bone in the body. Helps with weight-bearing and stabilization.
By Braus, Hermann [Public domain], via Wikimedia Commons
Talus The talus bone forms the primary connection between the lower leg and foot and is vital for mobility. In fact, the structure of the talus bone is so unique it can form the connection between numerous other bones such as the tibia, fibula, calcaneus (heel) and navicular or tarsal bones found in the foot.

Medial malleolus The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia.

Lateral malleolus The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the tibia.
Henry Vandyke Carter [Public domain], via Wikimedia Commons
Parts Function Image
Thigh Femur Supports the weight of the body and allowing motion of the leg. The femur articulates proximally with the acetabulum of the pelvis forming the hip joint, and distally with the tibia and patella to form the knee joint.

Metatarsals Metatarsals are convex in shape (arch upward), are long bones, and give the foot its arch. They work with connective tissues, ligaments, and tendons to provide movement in the foot

Cuneiform bones This bone is cube-shaped and connects the foot and the ankle. It also provides stability to the foot.

Cuboid bone The cuboid bone is one of the seven tarsal bones located on the lateral (outer) side of the foot. This bone is cube-shaped and connects the foot and the ankle. It also provides stability to the foot.

Navicular bone The navicular is a boat-shaped bone located in the top inner side of the foot, just above the transverse. It helps connect the talus, or anklebone, to the cuneiform bones of the foot

  • Part of the lateral rotators of the hip, along with the quadratus femoris, gemellus inferior, gemellus superior, obturator externus, and obturator internus
  • The piriformis laterally rotates the femur with hip extension and abducts the femur with hip flexion
 Arise:
  • The front of the sacrum by three fleshy digitations
  • Attached to the portions of bone between the first, second, third, and fourth anterior sacral foramina, and to the grooves leading from the foramina
  • A few fibers also arise from the margin of the greater sciatic foramen, and from the anterior surface of the sacrotuberous ligament.

Insertion:

  • The muscle passes out of the pelvis through the greater sciatic foramen, the upper part of which it fills
