Editor's Notes
c) Round ligament
The round ligament is a fibrous band of tissue that extends from the uterine fundus to the labia majora. Its primary function is to provide support to the uterus and help maintain its position within the pelvic cavity. During pregnancy, the round ligament helps to support the growing uterus.
c) Transverse diameter of the pelvic inlet
The ischial spines serve as important landmarks in obstetrics. The transverse diameter of the pelvic inlet is measured between the ischial spines during childbirth. This measurement helps assess the adequacy of the pelvic inlet for the passage of the fetal head.
c) Levator ani
The levator ani is a group of muscles that forms the pelvic floor. This muscle group provides crucial support to the pelvic viscera, including the bladder, uterus, and rectum. A strong and well-functioning levator ani is essential for maintaining pelvic organ position and preventing pelvic floor disorders.
d) Suspensory ligament of the ovary
The suspensory ligament of the ovary extends from the lateral border of the ovary to the pelvic side wall. It carries the ovarian vessels, including the ovarian artery and vein. This ligament plays a crucial role in providing vascular support to the ovary.
c) Cardinal ligament
The cardinal ligament provides support to the uterus and extends from the lateral wall of the uterus to the pelvic side wall. It contains important structures such as the uterine vessels and nerves and is essential for maintaining the position and stability of the uterus.
d) Pelvic floor muscles
Weakness or dysfunction of the pelvic floor muscles is commonly associated with stress urinary incontinence in women. The pelvic floor muscles play a crucial role in supporting the bladder and maintaining urinary continence. Strengthening these muscles is often a key component of managing and preventing stress urinary incontinence.
