What is the fundus of uterus?

The fundus of the uterus is the rounded, dome-shaped uppermost part of the uterus. It is located between the uterine body and the fallopian tubes. The fundus of the uterus expands and rises during pregnancy to accommodate the growing fetus.

Here are some key points about the fundus of the uterus:

1. Location: The fundus is the topmost portion of the uterus. It is situated above the level of the fallopian tubes and is the widest part of the uterus.

2. Shape and position: The fundus has a rounded or dome-shaped structure, resembling an upside-down bowl. In a non-pregnant uterus, the fundus is relatively flat, but it becomes more rounded during pregnancy.

3. Importance during pregnancy: The fundus of the uterus is an important landmark during pregnancy as it helps determine the gestational age and position of the fetus. It can be palpated by a healthcare provider during a prenatal examination to assess the growth and position of the baby.

4. Blood supply: The fundus of the uterus receives its blood supply from the uterine arteries, which branch off from the internal iliac arteries. These arteries provide nourishment to the endometrial lining and myometrium of the uterus.

5. Function: The fundus of the uterus plays a role in the contraction of the uterine muscles during labor, facilitating the expulsion of the baby during childbirth.

6. Abnormalities: Some abnormalities that may affect the fundus of the uterus include uterine fibroids (benign tumors), adenomyosis (endometrial tissue grows into the muscle wall), or uterine septum (a congenital condition where the uterus is divided by a muscular wall).

7. Clinical significance: The fundus of the uterus is examined clinically using techniques like palpation, ultrasound, or hysteroscopy. Any abnormalities or disorientation of the fundus can indicate uterine or fertility-related issues that may require medical attention.

Overall, the fundus of the uterus is a crucial part of the female reproductive system, particularly during pregnancy, and its examination provides valuable information regarding the health and development of the uterus.
