The 'broad ligament of the uterus' is the wide fold of
peritoneum that connects the sides of the
uterus to the walls and floor of the
pelvis. The name for the structure is misleading, because the term
ligament typically refers to tissue that connects
bones together.
Contents
The contents of the broad ligament include the following:
[1]
★
Fallopian tube
★
ovarian artery and
uterine artery
★
ovary
★
ovarian ligament
★
round ligament of uterus
Subdivisions
The broad ligament may be divided into three subcomponents:
[2]
★
Mesometrium - the mesentery of the uterus; the largest portion of the broad ligament
★
Mesosalpinx - the part that surrounds the
uterine tube
★
Mesovarium - the part that surrounds the
ovary
Some sources consider the
suspensory ligament of the ovary a part of the broad ligament
[2] while other sources just consider it a "termination" of the ligament.
[4]
Structure
The
peritoneum surrounds the
uterus is like a flat sheet that is folded over the uterus; on the sides of the uterus, this sheet of peritoneum comes in direct contact with itself, forming the double layer of peritoneum known as the broad ligament of the uterus.
The part where this peritoneal sheet is folded (i.e. the free edge) has the
uterine tubes running between the two layers; this part is known as the
mesosalpinx.
Function
The broad ligament serves as a mesentery for the uterus, ovaries, and the uterine tubes. It helps in maintaining the uterus in its position.
