## Summary

The uterus is an extraperitoneal female reproductive organ found in the pelvis. It is connected to the vagina inferiorly via the cervix, sits posterior to the urinary bladder and anterior to the rectum.

## Anatomy

The uterus contains a **fundus, body, uterine cavity and cervical canal** as well as the internal and external openings of the cervix, known as the ostium.

## Relations

- Anterior: urinary bladder-  the **vesicouterine pouch** separates the two structures
- Posterior: rectum - the **rectouterine pouch** or pouch of Douglas separates the two structures. 
- Superior: sigmoid colon
- Inferior: vagina


## Blood supply

The uterus gets its arterial supply from the **uterine artery**. The uterine veins drain the uterus into a **plexus** contained within the broad ligament.

The lymphatic drainage of the uterus is to the **aortic, inguinal, iliac and sacral nodes**.

## Innervation

The uterus is innervated by the **uterovaginal** and **inferior hypogastric plexuses.**

## Clinical points
- The pouches surrounding the uterus have clinical relevance as excess fluid can build up in them - although some fluid can be considered physiological, if there is a lot this can be a sign of intra-abdominal pathology.
- The relations of the uterus are important because in aggressive uterine cancer the tumour can extend through the uterus and into adjacent structures. This can make surgical resection extremely challenging if not impossibe.
