## Summary

The vulva or pudendum are terms used to refer to the external female genitalia. There are several structures involved in the vulva.

## Anatomy

**Mons pubis**

- a fat pad anterior to the pubic symphysis, often covered in coarse pubic hair. Located at the meeting of the labia majora

**Labia**

*Labia majora*

- Symmetrical skin folds that stretch from the mons pubis to posterior commissure. Typically covered in pubic hair.

*Labia minora*

- Two hairless skin folds. Anteriorly, they form the clitoral hood and posteriorly they create the "fourchette" skin fold. The labia minora lie medially to the labia majora.

**Vestibule**

The vestibule of the vagina is the space **surrounded by the labia minora**. It contains the **external urethral orifice, vagina** and the **ducts** of the **greater and lesser vestibular glands**.

On either side of the external urethral orifice there are **paraurethral glands**. The **hymen** is a thin mucous membrane that surrounds the lumen within the vaginal orifice. After the hymen ruptures, hymenal caruncles (or tags) may be left behind.

The **bulbs of the vestibule** are pairs of erectile tissue along either side of the vaginal orifice.

**Clitoris**

The clitoris is an erectile organ found at the anterior meeting of the labia minora - with the medial laminae of the labia minora forming the **frenulum** of the clitoris, and the lateral laminae forming the **prepuce** of the clitoris.

The **prepuce**, also known as the "hood" of the clitoris overlies the glans. Internally, the clitoris consists of two crura that join anteriorly to form the corpora cavernosa that engorge with blood to enlarge the clitoris on stimulation.

All three parts are innervated by **pudendal, ilioinguinal and genitofemoral nerves**.

## Clinical points

- Vulval cancers spread to lymph nodes in the groin rather than those in the pelvis.
- The anatomy of the clitoris is clinically relevant in the context of assessing female gential mutilation, and can also be implicated in trauma during childbirth.
