The female external genitalia, or vulva, comprises multiple specialized structures that serve reproductive, sexual, and urinary functions. Understanding the detailed anatomy of these structures is crucial for healthcare professionals in gynecology, urology, and sexual medicine. This anatomical guide presents both external anterior and internal anterolateral views to provide a complete understanding of vulvar structures.
Label Introductions
Prepuce The hood-like fold of skin that covers the glans clitoris. This structure contains numerous nerve endings and provides protection for the sensitive clitoral glans.
Glans Clitoris The external visible portion of the clitoris containing dense nerve endings. This highly innervated structure is crucial for sexual response and pleasure.
Labia Minora The inner vaginal lips that protect the vaginal opening and urethra. These thin, sensitive folds contain numerous blood vessels and nerve endings.
Corpus Cavernosum The erectile tissue that forms the body of the clitoris. These paired structures become engorged with blood during sexual arousal.
Bulb of Vestibule Paired erectile tissue located on either side of the vaginal opening. These structures contribute to sexual response and vaginal lubrication.
Urethral Opening The external orifice of the urethra located between the clitoris and vaginal opening. This opening serves as the terminus for urinary excretion.
Labia Majora The outer vaginal lips that provide protection for internal structures. These hair-bearing folds contain sebaceous glands and adipose tissue.
Vaginal Opening The entrance to the vaginal canal, surrounded by the hymenal remnants. This opening has significant elastic properties to accommodate childbirth.
Opening of Bartholin’s Gland The small ducts through which the Bartholin’s glands secrete their lubricating fluid. These openings are located on either side of the vaginal entrance.
Bartholin’s Glands Paired glands that produce lubrication during sexual arousal. These important structures can become infected, forming Bartholin’s cysts or abscesses.
Anus The terminal opening of the digestive tract. While not part of the vulva, its proximity requires consideration in vulvar examination and pathology.

Anatomical Organization
The female external genitalia exhibits complex layering and specialized tissues. Each component serves specific functions in reproduction, sexual response, and protection of internal structures. Understanding these relationships is crucial for clinical assessment and treatment.
Structural Components
Surface Anatomy
The vulvar surface presents distinct features:
- Specialized epithelial surfaces
- Transitional zones between tissues
- Glandular openings
- Vascular patterns
Deep Structures
Below the surface lie important components:
- Erectile tissues
- Neurovascular bundles
- Glandular structures
- Supporting fascia
Physiological Functions
Sexual Response
Vulvar structures participate in sexual function through:
- Vasocongestion mechanisms
- Sensory feedback pathways
- Lubrication production
- Orgasmic response
Protective Mechanisms
Protection is maintained through:
- pH regulation
- Microbiological balance
- Mechanical barriers
- Immunological defenses
Clinical Considerations
Examination Techniques
Proper assessment requires:
- Systematic inspection
- Tissue palpation
- Secretion evaluation
- Functional testing
Common Pathologies
Frequently encountered conditions include:
- Vulvar dermatoses
- Bartholin’s gland disorders
- Infectious processes
- Neoplastic conditions
Developmental Aspects
Embryological Origins
Development involves:
- Urogenital sinus derivatives
- Hormone-dependent differentiation
- Tissue specialization
- Neural development
Age-Related Changes
Changes occur throughout life:
- Prepubertal stage
- Reproductive years
- Menopausal transition
- Senescent changes
