1610s, "basin-like cavity formed by the bones of the pelvic girdle," from Modern Latin, from Latin pelvis "basin, laver," Old Latin peluis "basin," from PIE *pel- "container" (cf. Sanskrit palavi "vessel," Greek pelex "helmet," pelike "goblet, bowl," Old Norse and Old English full "cup").
pelvis pel·vis (pěl'vĭs)
n. pl. pel·vis·es or pel·ves (-vēz)
A basin-shaped structure of the vertebrate skeleton, composed of the innominate bones on the sides, the pubis in front, and the sacrum and coccyx behind, that rests on the lower limbs and supports the spinal column.
The cavity formed by this structure.
A basinlike or cup-shaped anatomical cavity.
Plural pelvises or pelves (pěl'vēz)
The basin-shaped structure in vertebrate animals that joins the spine and lower or hind limbs. In primates, the pelvis is composed of the two hipbones joined to the sacrum. It contains, protects, and supports the intestines, bladder, and internal reproductive organs.
The bowl-shaped group of bones connecting the trunk of the body to the legs and supporting the spine. The pelvis includes the hip bones and the lower part of the backbone.
in human anatomy, basin-shaped complex of bones that connects the trunk and legs, supports and balances the trunk, and contains and supports the intestines, urinary bladder, and internal sex organs. The pelvic girdle consists of paired hipbones, connected in front at the pubic symphysis and behind by the sacrum; each is made up of three bones-the blade-shaped ilium, above and to either side, which accounts for the width of the hips; the ischium, behind and below, on which the weight falls in sitting; and the pubis, in front. All three unite in early adulthood at a triangular suture in the acetabulum, the cup-shaped socket that forms the hip joint with the head of the femur (thighbone). The ring made by the pelvic girdle functions as the birth canal in females. The pelvis provides attachment for muscles that balance and support the trunk and move the legs, hips, and trunk. In the infant the pelvis is narrow and nonsupportive. As the child begins walking, the pelvis broadens and tilts, the sacrum descends deeper into its articulation with the ilia, and the lumbar curve develops.
