What is broad ligament of uterus?
The broad ligament is a two-layered fold of peritoneum that extends from the sides of the uterus to the floor and lateral walls of the pelvis inferiorly and the adnexa superiorly. The broad ligament helps to hold the uterus in its anatomic position, although its contribution is not considered to be central.
Where is the round ligament of the uterus located?
The round ligament of the uterus originates at the uterine horns, in the parametrium. The round ligament exits the pelvis via the deep inguinal ring. It passes through the inguinal canal, and continues on to the labia majora. At the labia majora, its fibers spread and mix with the tissue of the mons pubis.

Overview
The round ligaments are rope-like bands of connective tissue that support the uterus (womb). The scientific term for this round ligament is the gubernaculum.
Function
The round ligaments support and anchor the uterus. During pregnancy, the round ligaments stretch. They get wider and longer to support the growing uterus.
Anatomy
There are two round ligaments, one on each side of the uterus. The uterus is a hollow, pear-shaped organ in the pelvis (bowl-shaped area of bone that connects your torso and legs). During pregnancy, a developing baby grows in the uterus. The muscular uterus can expand as the baby grows.
Conditions and Disorders
Several conditions can affect the round ligaments during a woman’s reproductive years. These include:
Care
During pregnancy, it may help to do gentle stretches of the pelvis and hips. If you experience round ligament pain, stop doing the movement that triggered the pain and rest until it goes away.
Which ligaments support the middle aspect of the uterus?
Middle aspect - supported by the cardinal, pubocervical and uterosacral ligaments. The inferior aspect of uterus is supported by the structures in the pelvic floor - the levator ani, perineal membrane and perineal body.
What are the ligaments of the female reproductive tract?
The ligaments of the female reproductive tract are a series of structures that support the internal female genitalia in the pelvis. The ligaments of the female reproductive tract can be divided into three categories: Broad ligament – a sheet of peritoneum, associated with both the uterus and ovaries.
What is the ligament that attaches the cervix to the sacrum?
The uterosacral ligaments are also bilateral fibrous bands, which attach the cervix to the sacrum. They are also known as the recto-uterine ligaments or sacrocervical ligaments. This supports the uterus and holds it in place.
What is the function of the ovarian ligament?
The function of this ligament is to contain the ovarian vessels and nerves (ovarian artery, ovarian vein, ovarian nerve plexus and lymphatic vessels). Ligaments Associated with the Uterus. There are a number of ligamentous structures that attach to the uterus. They can be divided by where they attach to the uterus:
What is the suspensory ligament?
The suspensory ligament of ovary extends outwards from the ovary to the lateral abdominal wall. It consists of a fold of peritoneum, thus some sources consider it to be part of the broad ligament. The function of this ligament is to contain the ovarian vessels and nerves (ovarian artery, ovarian vein, ovarian nerve plexus and lymphatic vessels).
Where is the ovarian ligament?
The ovarian ligament is attached to the ovary inferiorly. It connects the ovary to the side of the uterus. Structurally, it is a fibrous band of tissue that lies within the broad ligament. It joins the uterus just below the origin of the fallopian tubes.

The function of the uterine cervix during pregnancy is described at the end of the article.
What is the uterus?
The uterus is a fibromuscular organ that is responsible for protecting and nurturing the developing conceptus. It is described as having two distinct parts: a muscular uterine corpus and a more fibrous uterine cervix. Definitions are important here, as it is easy to assume that the cervix is an entirely separate organ.
What ligaments pass from the cervix to the sacral vertebrae?
The uterosacral ligaments pass from the posterior and lateral supravaginal portions of the cervix to the middle three sacral vertebrae, 4 though other attachments include levator ani, coccygeus and obturator internus. 5 The ligament is thought to facilitate the passing of nerves to the pelvic viscera.

What is the junctional zone of the uterus?
Vascular spaces fuse and become interconnected, forming the placenta, which supplies oxygen and nutrition to the embryo and fetus. The myometrium of the uterus mostly consists of smooth muscle. The innermost layer of myometrium is known as the junctional zone, which becomes thickened in adenomyosis.
What are the four regions of the uterus?
The uterus can be divided anatomically into four regions: the fundus – the uppermost rounded portion of the uterus, the corpus (body), the cervix, and the cervical canal. The cervix protrudes into the vagina. The uterus is held in position within the pelvis by ligaments, which are part of the endopelvic fascia.
