12 Facts About Human pelvis

The gap enclosed by the bony Human pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs and the rectum, while the pelvic floor at the base of the cavity assists in supporting the organs of the abdomen.

In mammals, the bony Human pelvis has a gap in the middle, significantly larger in females than in males.

The bony Human pelvis is the part of the skeleton embedded in the pelvic region of the trunk.

The pelvic inlet or superior pelvic aperture, which leads into the lesser Human pelvis, is bordered by the promontory, the arcuate line of ilium, the iliopubic eminence, the pecten of the pubis, and the upper part of the pubic symphysis.

Alternatively, the Human pelvis is divided into three planes: the inlet, midplane, and outlet.

Each side of the Human pelvis is formed as cartilage, which ossifies as three main bones which stay separate through childhood: ilium, ischium, pubis.

Skeleton of the Human pelvis is a basin-shaped ring of bones connecting the vertebral column to the femora.

The lateral superficial muscles, the transversus and external and internal oblique muscles, originate on the rib cage and on the Human pelvis and are attached to the anterior and posterior layers of the sheath of the rectus.

Notwithstanding the popularity of this simple classification, the Human pelvis is much more complicated than this as the Human pelvis can have different dimensions at various levels of the birth canal.

Classification of Caldwell and Moloy was influenced by earlier classifications attempting to define the ideal female Human pelvis, treating any deviations from this ideal as dysfunctions and the cause of obstructed labour.

In heavy mammals, especially in quadrupeds, the Human pelvis tend to be more vertically oriented because this allows the Human pelvis to support greater weight without dislocating the sacroiliac joints or adding torsion to the vertebral column.

Present-day morphology of the Human pelvis is inherited from the Human pelvis of our quadrupedal ancestors.
