Pelvis

The pelvis, or pelvic bone, derived from the Latin word for 'basin', is an anatomical structure found in most vertebrates. It is the name given to both a bony structure or pelvic girdle connecting the base of the spine to the rear limbs, and the region of the body defined by that structure. The muscles and tissue beneath the pelvic girdle are known as the pelvic floor. The rounded epiphysis of the femur called the Head articulates with the pelvic bone at the Hip Joint at the acetabulum.
