1) a basin-shaped structure in the skeleton of many vertebrates that is formed by the pelvic girdle together with the sacrum and often various coccygeal and caudal vertebrae and that in humans is composed of the two hip bones bounding it on each side and in front while the sacrum and coccyx complete it behind
2) PELVIC CAVITY
3) RENAL PELVIS

* * *

n. (pl. pelves)
1. the bony structure formed by the hip bone, sacrum, and coccyx: the bony pelvis. The hip bones are fused at the back to the sacrum to form a rigid structure that protects the organs of the lower abdomen and provides attachment for the bones and muscles of the lower limbs.
2. the lower part of the abdomen.
3. the cavity within the bony pelvis.
4. any structure shaped like a basin, e.g. the expanded part of the ureter in the kidney (renal pelvis).
pelvic adj.

pel·vis (pelґvis) pl. pelґves [L. “basin”] 1. [TA] the inferior portion of the trunk of the body, bounded anteriorly and laterally by the two hip bones and posteriorly by the sacrum and coccyx; see illustration. The pelvis is divided by a plane passing through the terminal lines into the p. major superiorly and the p. minor inferiorly. The superior boundary of the pelvic cavity is the inlet (apertura pelvis superior [TA]), and the inferior boundary of the pelvis minor is the outlet (apertura pelvis inferior [TA]), which is bounded by the coccyx, the symphysis pubis, and the ischium of either side. The outlet is closed by the coccygeus and levator ani muscles and the perineal fascia, which form the floor of the pelvis. The inlet and outlet each have three important diameters: an anteroposterior (conjugate), an oblique, and a transverse, the relations of which determine types variously classified by different authors (see illustration under diameter). 2. any basinlike structure.

Anterior aspect of female (A) and male (B) pelvis.
