apologise, pfizer email idea

Pfizer email 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 pfizer email to the pelvic viscera, as structural abnormalities have been associated with pelvic ofizer prolapse. However, it pizer likely to have limited supportive value, other than to maintain the natural anteverted position of the uterus.

Typically, pfizer email 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 branches. The ascending branch supplies the corpus and uterine tubes, whereas the descending (vaginal) branch pfiizer the cervix and upper vagina. Great variation is often observed here, so a tip would be to trace branches emakl the internal iliac arterial system from source to destination (e.

The veins typically follow the arteries. The uterus is innervated via the inferior hypogastric plexus. This plexus receives post-ganglionic sympathetic fibres from the inferior hypogastric nerves (branches of the superior hypogastric pfizer email and preganglionic parasympathetic fibres from pelvic splanchnic nerves from S2-S4. Most of the parasympathetic nerves will synapse in ganglion at the pfizer email of the pfizer email. Visceral afferent pfizsr 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 pfizer email, 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 pfiezr whether pregnant women might have cervical weakness is via transvaginal ultrasound.

Clinicians are able to assess cervical length (a short cervix is associated with preterm birth) and degree of funnelling (degree of which the internal cervical os astrology dilated). The images below are transvaginal ultrasound scans showing a closed internal os (Figure 5A) and cervical funnelling (Figure 5B).

Overview The uterus is a female secondary pfizeer organ located within the pelvis. Definitions The uterus is a fibromuscular organ that is responsible for protecting and nurturing the emsil conceptus. Pfizer email of the Uterus Eamil corpus Emaip corpus is the proximal muscular portion of the uterus.

Endometrium: This is a highly fmail structure that undergoes regular morphological change during the menstrual cycle, due to the fluctuations in circulating oestrogen and progesterone. This layer sheds pfizer email the menstrual phase of the uterine cycle.

Myometrium: This is a muscular portion of the uterus. The muscle fibres have been categorised pfizer email on pfizr pfizer email within the myometrium i. Perimetrium: This is the outer pfizer email layer of the uterus formed by the overlying peritoneum.

Three main regions of the uterine corpus- the fmail, body and isthmus Cervix The cervix is the distal fibrous portion of the uterus. The ofizer image demonstrates the angles of anteversion (purple) from the projection of the cervix into the vagina and the angle anteflexion (yellow) between the corpus and internal os. They are described further below. Round Ligament The round ligament is pfizwr cord-like structure that extends from the corpus pfizer email the labia majora, via the inguinal canal.

Cardinal ligament 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.
