Hip Bone, Innominate Bone

The pelvic bone is one of the largest and most complex bones in the human body. It is formed by the fusion of three bones: the ilium, the ischium and the pubis. Each of these bones has a different shape and function, but together they provide stability to the hip joint and provide support for the lower limbs.

The main parts of the pelvic bone include the acetabulum, pubis, ischium and obturator foramen. The acetabulum is a deep depression on the outside of the pelvic bone that connects to the head of the femur to form the hip joint. The pubic bone is located on the lower anterior corner of the pelvic bone and connects to the pubic bone of the opposite side through the symphysis. The ischium is located at the posterior lower corner of the pelvic bone and forms part of the bony structure of the pelvis. The obturator foramen is located between the pubis and ischium and is a passage for nerves, blood vessels and muscles.

The pelvic bone plays an important role in maintaining the body in an upright position and allowing movement of the lower limbs. Thanks to its complex structure, it provides stability to the hip joint and protects the internal organs in the abdominal cavity.

In conclusion, the pelvic bone is a complex bony structure that plays an important role in maintaining the body in an upright position and allowing movement of the lower limbs. Its anatomical structure and functional significance are important for understanding many aspects of human anatomy and physiology.



The pelvic bone (Hip Bone) is a bone that is formed as a result of the fusion of three bones: the ilium, the ischium and the pubis. It is one of the largest bones in the human body and plays an important role in the formation of the pelvis. The pelvic bone connects to the femur through the acetabulum, which forms the hip joint.

The pubis and ischium border the obturator foramen, located just below the acetabulum and slightly in front. The right and left femurs also form part of the pelvis, providing stability and protection to the hip joint.

The pelvic bone has a complex structure and consists of several sections: the acetabulum, the acetabulum fossa, the femoral neck fossa, the femoral head fossa and the ischium fossa. Each of these sections performs its function in conjunction with other bones and tissues of the body.

The pelvic bone is one of the main elements of the human musculoskeletal system. It provides stability, balance and movement to the body and protects internal organs. In addition, the pelvic bone is involved in the formation of the female pelvis and affects reproductive function.

Thus, the pelvic bone plays an important role in many aspects of human life, and its health and functionality are of great importance to the overall well-being of the body.



The pelvic bone or Innominate bone is one of the largest fused bones of the skeleton, consisting of four separate parts: the pubis, the ilium, and both ischiums. It forms the frame of the pelvis and takes on the loads associated with upright posture.

The pelvis is located below the waist, at the bottom of the chest, covering the femur with the hemispheres at the top, forming the acetabulum and two spoons fused on the opposite side. The sacrum is located at the back, and below it merges with the quadrate.

The acetabulum, providing articulation of the pelvic bone with the femur, is divided into two sections: upper and lower. Along the upper edge of the acetabulum there is a concave platform - the acetabulum area. Just below it on the front side of the femoral neck is the oval head.
