    Study Notes

    Clitoris

    • Erectile tissue located beneath the junction of the labia minora
    • Composed of glans, a corpus (body), and two crura
    • Crura are anchored to the periosteum of the ischiopubic rami
    • Highly sensitive structure involved in sexual arousal

    Vestibule

    • Almond-shaped region between the clitoris and vaginal introitus
    • Represents a functionally mature segment of the urogenital sinus from embryonic development
    • Span extends from the clitoris to the posterior fourchette

    Glandular Structures in the Vestibule

    Periurethral Glands (Skene Glands)

    • Also known as lesser vestibular glands
    • Type: Tubuloalveolar glands
    • Located adjacent to the urethra
    • Secretes lubrication at the urethral opening
    • Associated pathology: Urethral diverticulum

    Vulvovaginal Glands (Bartholin Glands)

    • Also called greater vestibular glands
    • Type: Compound alveolar/compound acinar glands
    • Positioned at the 5 and 7 o'clock positions of the vagina
    • Provides lubrication to the vagina; openings are outside the hymen at the posterior vaginal aspect
    • Associated pathology: Bartholin cyst/abscess

    Subdivisions of Female Reproductive Organs

    External Genitalia (Located outside the true pelvis)

    • Perineum
    • Mons pubis
    • Clitoris
    • Urethral (urinary) meatus
    • Labia majora and minora
    • Vestibule
    • Greater vestibular (Bartholin) glands
    • Skene glands
    • Periurethral area

    Internal Genitalia (Located within the true pelvis)

    • Vagina
    • Cervix
    • Uterus
    • Uterine (fallopian) tubes
    • Ovaries

    Homologous Structures Between Male and Female Reproductive Systems

    • Genetic sex is determined at fertilization (XX or XY)
    • Gonadal sex is established by differentiation of primordial gonads into testis or ovary
    • Phenotypic sex emerges based on testicular function; absence leads to female development

    Structures Comparison

    • Genital Ridge: Testis in males, Ovary in females
    • Mesonephric Ducts: Epididymis, ductus deferens, ejaculatory duct in males, Gartner duct in females
    • Paramesonephric Ducts: Prostatic utricle in males, uterus, fallopian tubes, upper vagina in females
    • Genital Tubercle: Glans penis in males, glans clitoris in females
    • Urogenital Sinus: Bulbourethral glands in males, Skene glands in females
    • Urogenital Folds: Ventral shaft of penis in males, labia minora in females
    • Labioscrotal Swelling: Scrotum in males, labia majora in females

    Vulva (Pudenda)

    • The term refers to the external genitalia visible in the perineal area
    • Encompasses all structures from the mons pubis to the perineal body

    Structures of the Vulva

    • Mons pubis
    • Clitoris
    • Urinary meatus
    • Labia majora and minora
    • Vestibule
    • Hymen
    • Vaginal orifice
    • Urethral opening
    • Glandular structures

    Mons Pubis

    • Rounded, fatty prominence located anterior to the pubic symphysis, tubercles, and superior pubic rami
    • Comprised of fatty subcutaneous tissue with pubic hair development post-puberty
    • The surface is continuous with the anterior abdominal wall
