Pelvis , also called bony pelvis or pelvic girdle , in human anatomy , basin-shaped complex of bones that connects the trunk and the legs, supports and balances the trunk, and contains and supports the intestines , the urinary bladder , and the internal sex organs. The pelvis 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 pelvis functions as the birth canal in females. The pelvis provides attachment for muscles that balance and support the trunk and move the legs, the hips, and the trunk. In the human 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 of the lower back develops.

The pelvis is the lower portion of the trunk, located between the abdomen and the lower limbs. The floor of the pelvis is made up of the muscles of the pelvis, which support its contents and maintain urinary and faecal continence. There are many organs that sit in the pelvis, including much of the urinary system, and lots of the male or female reproductive systems. The skin, tissues and organs in the pelvis are supplied by the vasculature of the pelvis, and innervated by many nerves of the pelvis, including the pudendal nerve.

The pelvis plural pelves or pelvises is either the lower part of the trunk of the human body  between the abdomen and the thighs sometimes also called pelvic region of the trunk or the skeleton embedded in it  sometimes also called bony pelvis , or pelvic skeleton. The pelvic region of the trunk includes the bony pelvis, the pelvic cavity the space enclosed by the bony pelvis , the pelvic floor , below the pelvic cavity, and the perineum , below the pelvic floor. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs sex organs and the rectum , while the pelvic floor at the base of the cavity assists in supporting the organs of the abdomen.
The pelvic girdle is a ring-like bony structure, located in the lower part of the trunk. It connects the axial skeleton to the lower limbs. In this article, we shall look at the anatomy of the pelvic girdle — its bony landmarks, functions, and its clinical relevance. Ligaments attach the lateral border of the sacrum to various bony landmarks on the bony pelvis to aid stability. Fig 1 — The pelvic girdle is formed by the hip bones, sacrum and coccyx. The strong and rigid pelvis is adapted to serve a number of roles in the human body. The main functions being:. The junction between the greater and lesser pelvis is known as the pelvic inlet. The outer bony edges of the pelvic inlet are called the pelvic brim. Fig 2 — The greater and lesser pelvis.
