Uterus.

The size and position of the uterus vary with age, menstrual cycle, and parity. On ultrasound measurements, the Normal size of the uterus is from 7 cm to 9 cm in patients with multiple pregnancies, and about 4 cm to 5 cm wide.

The uterus is divided into three parts: the fundus, the body and the cervix.

The uterine cavity is lined by the endometrium which is formed by a mucous membrane. The endometrium undergoes monthly cyclical changes, this process is called menstrual cycle , this cycle occurs in response to hormonal stimulation and in preparation for an implantation in case a fertilized egg gets to the cavity, The uterus is suspended in the middle of the pelvic cavity by the broad ligament that anchors it to the pelvic sidewalls.

There are 2 different Normal variation of Uterus called Anteverted and Retroverted, is a genetic trace and both uterus are completely normal to carry a pregnancy.

fallopian Tubes.

There is one tube on each side, connecting the ovaries to the uterus, its length measures about 10 cm. The lateral end is closely adjacent to the medial side of the ovaries where is expanded and fimbriated.

Functions of the Tubes.

  • to facilitate the transport and provide nutrients to the ova and spermatozoa.
  • to act as the site for fertilization, the process that occurs specifically at the ampullary portion.
  • to transport the zygote (fertilized egg) into the uterine cavity and to provide nutrients on the way.

Note: Fallopian tubes are not seen on ultrasound unless there is fluid or blood inside which is considered abnormal.

Ovaries.

The almond shape glands, one on each side, vary in size and position with age, menstrual cycle, parity, and degree of distention of the surrounding organs.

The ovary is made of 2 parts, central medulla, and surrounding cortex. The cortex contains the follicles in various stages of development.
