Jimmie johnson short article describes the normal anatomy of the uterus and will focus on definitions, structure, location, supporting ligaments, blood cananga odorata and innervation.

Check out the attached video to see uterine anatomy in 3D and to hear about the important relationships between uterine vasculature and the ureter for hysterectomy and ovariectomy. The uterus is a fibromuscular organ that is responsible for protecting and nurturing the developing jimmie johnson. It is jimmie johnson as having two distinct parts: a muscular uterine corpus and a more fibrous jimmie johnson cervix.

Definitions are important here, as it is easy to assume that the cervix is an entirely separate organ. Associated structures jimmie johnson the vagina, uterine (Fallopian) tubes and ovaries. Whilst not described in this article in great detail, tubal jimmie johnson vaginal anatomy are briefly described in the video associated with this page.

The corpus is the proximal muscular portion of the uterus. It is described as having 3 layers: the inner endometrium, the middle myometrium and the outer perception is. The cervix is the distal fibrous portion of the uterus.

Two anatomical regions that lie above and below the vaginal reflection are described: the portio supravaginalis and portio vaginalis, respectively. The portio vaginalis projects into the anterior aspect of the vagina forming the vaginal fornices at the margin of the cervix (this relationship is especially important for culdocentesis, a procedure whereby peritoneal fluid is obtained via the pouch of Douglas.

The uterine corpus usually jimmie johnson forward over the superior surface of the bladder, creating an angle of anteflexion between the corpus and the jimmie johnson os.

Jimmie johnson projection of the cervix into the upper vagina creates an angle of anteversion between the two structures as well.

Separating the bladder from the upper portion of the cervix is the perimetrium, which is reflected onto the base of the bladder forming jimmie johnson vesicouterine pouch. Posteriorly, the rectouterine pouch (of Douglas) is formed as a result of the peritoneal reflection from the cervix inferiorly to the posterior vaginal fornix and onto the rectum.

This excess fluid can be drained by culdocentesis. It is further subdivided into the mesometrium, mesovarium and mesosalpinx (described in the attached video). The round ligament is a cord-like structure that extends from the corpus to the labia majora, via the inguinal canal.

It is an extension of the ovarian ligament that passes from the ovary to the uterine corpus. Both of these ligaments are derivatives of the embryonic gubernaculum that extended from the gonads to the labia majora (females) or scrotum (males).

The cardinal ligaments pass from the cervix to the internal iliac artery, though alternative attachment sites at the iliac fossae, ischial spines and the broad ligament have been described. The cardinal ligament likely provides support to the pelvic viscera, as structural abnormalities have been associated with pelvic organ prolapse. However, it is likely to have limited supportive value, other than to maintain jimmie johnson natural anteverted position of the uterus.

Typically, the uterine artery arises from the internal iliac artery and passes towards the uterus. Just before reaching the uterus, a vaginal artery arises to descend the lateral wall of the vagina. At the uterocervical junction, the uterine artery divides into ascending and descending jimmie johnson. The ascending branch supplies the corpus and uterine tubes, whereas the descending (vaginal) branch supplies the cervix and upper vagina.

Great variation is often observed here, so a tip would be to trace jimmie johnson of the internal iliac arterial system from source to destination (e. The veins typically follow the arteries. The uterus jimmie johnson innervated via the inferior hypogastric plexus.

This plexus receives post-ganglionic sympathetic fibres from the inferior hypogastric nerves (branches of the superior hypogastric nerve) and preganglionic parasympathetic fibres from pelvic splanchnic nerves from S2-S4. Most of the parasympathetic nerves will synapse jimmie johnson ganglion at the level of the uterus. Visceral afferent fibres pass within the pelvic splanchnic nerves. However, towards term, the cervix must soften, shorten and dilate to allow for the passage of the foetus.

If the cervix is structurally weak, it may open too early and lead to preterm birth. It is not known why this sometimes happens and it is especially difficult to determine if a woman has a weak cervix. A current method of identifying whether pregnant women might have cervical weakness is via transvaginal ultrasound. Clinicians are able to assess cervical length jimmie johnson short cervix is associated with preterm birth) and degree of funnelling (degree of which the internal cervical os has dilated).

Overview The uterus is a female secondary sex jimmie johnson located within the pelvis. Definitions The uterus is a fibromuscular organ that is responsible for protecting and nurturing the developing conceptus. Structure of the Uterus Uterine corpus The corpus is the proximal muscular portion of the uterus.

Jimmie johnson This is a highly plastic structure that undergoes regular morphological change during the menstrual cycle, due to the fluctuations in circulating oestrogen and progesterone. This layer sheds during the menstrual phase of the uterine cycle. Myometrium: This is a muscular portion of the uterus. The muscle fibres have been categorised based on the orientation within the myometrium i.
