Sexual arousal

sexually arousedarousalaroused
Clitoral erection is the result of a complex interaction of psychological, neural, vascular and endocrine factors, and is usually, though not exclusively, associated with sexual arousal. This may result from any of various physiological stimuli, including sexual arousal.
A number of physiological responses occur in the body and mind as preparation for sexual intercourse and continue during it. Male arousal will lead to an erection, and in female arousal the body's response is engorged sexual tissues such as nipples, vulva, clitoris, vaginal walls and vaginal lubrication.

Corpus cavernosum of clitoris

corpus cavernosum clitoridiscorpora cavernosaclitoral corpus cavernosum
Clitoral erection occurs when the corpora cavernosa, two expandable erectile structures, become engorged with blood.
The corpus cavernosum of clitoris is one of a pair of sponge-like regions of erectile tissue which contain most of the blood in the clitoris during clitoral erection.

Clitoris

clitoralclitoral glansglans clitoridis
Clitoral erection is a physiological phenomenon where the clitoris becomes enlarged and firm. The extrusion of the glans clitoridis and thinning of the skin enhances sensitivity to physical contact.
Although the clitoral body becomes engorged with blood upon sexual arousal, erecting the clitoral glans, some sources describe the clitoral glans and labia minora as composed of non-erectile tissue; this is especially the case for the glans.

Bulbospongiosus muscle

bulbospongiosusbulbocavernosusbulbocavernosus muscle
The ischiocavernosus and bulbocavernosus muscles contract to compress the dorsal vein of the clitoris to stop drainage of the clitoris, trapping the blood.
In females it contributes to clitoral erection and the contractions of orgasm, and closes the vagina.

Homology (biology)

Labia majora

The part visible on the outside varies in size from a few millimeters to one centimeter and is located hidden in the upper labial fold.

Hemodynamics

Any type of motion can increase blood flow to this organ and this results in increased secretions which lubricate the vagina.

Vaginal lubrication

Physiology

Smooth muscle

smooth muscle cellssmooth musclessmooth muscle cell
During sexual arousal, arterial blood flow to the clitoris is increased, and trabecular smooth muscle within the clitoris relaxes allowing blood to engorge the erectile tissues.

Ischiocavernosus muscle

The ischiocavernosus and bulbocavernosus muscles contract to compress the dorsal vein of the clitoris to stop drainage of the clitoris, trapping the blood.

Corpus spongiosum penis

corpus spongiosumcorpus cavernosum urethræcorpus cavernosum
There is also a strip of erectile tissue (similar to the placement of the corpus spongiosum in males) running along the ventral surface of the corpus cavernosa main body that connects the glans clitoridis to the commissure of the vestibular bulbs.

Endothelium

The erectile tissues are composed of endothelium-lined vascular spaces in a trabecular matrix, with the endothelium-lined vascular spaces surrounded by smooth muscle capable of contraction and relaxation.

Nocturnal clitoral tumescence

Nocturnal clitoral tumescence (NCT) is a spontaneous swelling of the clitoris during sleep or when waking up. Similar to the process in males, nocturnal penile tumescence, females experience clitoris tumescence or engorgement of the vagina mainly during REM sleep phase.

Cavernous nerves

cavernous nerves of penis
The cavernous nerves are post-ganglionic parasympathetic nerves that facilitate penile erection and clitoral erection.

Labia minora

Yet the hood is movable and can slide during clitoral erection or be pulled upwards a little for greater exposure of the clitoris to sexual stimulation.
