The clitoris is a sensory organ of the vulva made up of erectile tissue and a dense supply of nerves. In terms of clitoris anatomy, only a small tip is visible externally; most of the structure sits inside the body, extending around the front of the vaginal canal.
What the clitoris is
The clitoris is a single organ with multiple connected parts, most of which are hidden beneath the surface of the vulva. It is composed largely of erectile tissue — spongy tissue that fills with blood and becomes firmer when blood flow increases.
A defining feature of clitoris anatomy is its sensory density. According to the Cleveland Clinic, the clitoris contains thousands of nerve endings, making it one of the most sensitive structures in the body. Its primary recognized function is sensation.
The external parts
When people refer to "the clitoris" in everyday language, they usually mean the part they can see. In anatomy, this is only the visible tip.
The glans
The glans clitoris is the small, rounded tip located at the top of the vulva, where the inner labia (labia minora) meet. Its size varies considerably from person to person — descriptions range from about the size of a pea to larger. All of these variations fall within the normal range.
The clitoral hood
The clitoral hood is a fold of skin formed where the inner labia come together at the top. It covers and protects the glans. The amount of glans visible beneath the hood differs between individuals, and this too is a normal anatomical variation.
The internal parts
Most of the clitoris is internal. These parts are not visible from the outside but make up the majority of the organ.
- Body: Located behind the glans, the body of the clitoris extends inward and then divides.
- Crura: Two leg-like extensions, called the crura, branch out from the body. They run along either side of the vaginal canal, giving the internal clitoris a shape often compared to a wishbone.
- Vestibular bulbs: A pair of structures made of erectile tissue that sit between the crura, along the sides of the vaginal opening.
Together, these internal structures mean the clitoris is far larger than its visible tip suggests.
How the clitoris relates to other anatomy
The clitoris is one component of the female reproductive anatomy and a key part of the vulva. The vulva also includes the labia majora and minora, the urethral opening and the vaginal opening.
Interestingly, the clitoris and the penis develop from the same embryonic tissue. This is why both are built largely from erectile tissue. The anatomy and the way erections work in penile tissue share underlying similarities with the way clitoral erectile tissue responds, even though the structures and roles differ.
What is normal
Clitoral anatomy varies widely, and there is no single "correct" appearance.
- The size of the visible glans differs from person to person.
- The amount of hood covering the glans varies.
- These differences are normal and are not, on their own, signs of a health problem.
When to speak to a healthcare provider
Anatomical variation is normal, but certain changes are worth discussing with a clinician. Consider seeking advice if you notice:
- New pain, persistent itching, burning or discomfort in the area
- Swelling, lumps, sores or unusual changes in skin colour or texture
- A noticeable change in size or appearance that develops over time
- Any symptom that worries you or affects daily life
These guidelines are general education only and are not a substitute for an assessment by a qualified healthcare professional, who can examine the area and advise on next steps.
The bottom line
Clitoris anatomy is more extensive than the small visible tip suggests. The organ includes the external glans and hood and the internal body, crura and vestibular bulbs — all built from nerve-rich erectile tissue. It is one part of the vulva, distinct from the vagina, and its size and appearance vary normally from person to person. Understanding this structure supports general body literacy and makes it easier to recognise when a change is worth raising with a healthcare provider.
