The pelvic inlet or superior aperture of the pelvis is a planar surface which defines the boundary between the pelvic cavity and the abdominal cavity (or, according to some authors, between two parts of the pelvic cavity, called lesser pelvis and greater pelvis).
In the third maneuver the health care provider attempts to determine what fetal part is lying above the inlet, or lower abdomen. [2] The individual performing the maneuver first grasps the lower portion of the abdomen just above the pubic symphysis with the thumb and fingers of the right hand. This maneuver should yield the opposite information ...
Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry results.
The pelvic inlet is typically used to divide the abdominopelvic cavity into an abdominal (above the inlet) and a pelvic cavity (below the inlet). Sometimes, the pelvis cavity is considered to extend above the pelvic inlet, and in this case the pelvic inlet is used to divide the pelvic cavity into a false (above the inlet) and a true pelvis ...
In a 1982 study, pelvic contractions of 11 women who manually self-stimulated to orgasm were monitored using an anal probe and a vaginal probe simultaneously. Near the perceived start of orgasm, a series of regular contractions began in 9 of the women, with anal and vaginal contractions synchronizing with each other.
The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor. The pelvic cavity primarily contains the reproductive organs, urinary bladder, distal ureters, proximal urethra, terminal sigmoid colon, rectum, and ...
A Kegel perineometer or vaginal manometer is an instrument for measuring the strength of voluntary contractions of the pelvic floor muscles. Arnold Kegel (1894–1972) was the gynecologist who invented the Kegel perineometer (used for measuring vaginal air pressure) and Kegel exercises (squeezing of the muscles of the pelvic floor).
As pressure on the cervix increases, a sensation of pelvic pressure is experienced, and, with it, an urge to begin pushing. At the beginning of the normal second stage, the head is fully engaged in the pelvis; the widest diameter of the head has passed below the level of the pelvic inlet.
