the rib cage
The sacrum articulates with the hip bones of the pelvis.
The sacrum articulates with the ilium bones of the pelvis to form the sacroiliac joints.
The proximal end of the femur articulates with the acetabulum, which is the socket joint of the pelvis. The acetabulum is formed by the fusion of the three bones which make up the pelvis, the ischium, the ilium and the pubis. The distal end of the femur articulates with the patellae (knee caps) and the tibia.
The Femur Articulates (Forms a joint) with the Acetabularium of the pelvis bone at the junction of Ilium and Ischium. This is a ball and Socket Joint. And this is at the proximal end of the Femur. The distal end of the Femur articulates with the Tibia and Fibula (The bones of the shank region). This is a hinge joint.
It articulates with each vertebra. Plus the occipital bone of the skull and the 12 pairs of ribs.
The Ilium, Ischium and Pubis bones are the three main bones of the pelvis that are fused together
the femurs and the sacrum
The pelvis is one bone.
The head of the femur articulates with the os coxa (pelvis) at the acetabulum. The acetabulum is the rounded socket that the head of the femur fits into. It also allows sliding of the pelvic bones and rotation. This joint is a synovial joint and is an example of a "ball-and-socket" joint.
No fish do not have a pelvis. Most fish do have bones, just not a pelvis.
THE SACRUM AND THE ILIUM ARE THE LARGEST BONES OF THE PELVIS AND THE ARE IN THE UPPER REGION OF THE PELVIS FOR A COMPLETE LIST OF THE PELVIC BONES SEE http://en.wikipedia.org/wiki/Pelvic_bone
There are two. They are at the point where the femurs and the pelvis join.
