Study Notes

Viscera of the Pelvis

Organs located within the pelvis:
- Gastrointestinal organs
- Urinary organs
- Reproductive organs and accessory structures (sex-dependent)

Gastrointestinal Viscera in the Pelvis

Cecum and ascending colon: located in the greater pelvis on the right side
Descending colon: becomes continuous with the sigmoid colon at the pelvic brim
Sigmoid colon: joins with the rectum at the level of the mid-sacrum and becomes fixed to the posterior pelvic wall
Rectum: follows the curvature of the sacrum and coccyx onto the pelvic floor, where it penetrates the levator ani muscle and becomes the anal canal

Female Reproductive Organs

Organs and structures:
- Ovaries
- Ovarian tubes (also known as Fallopian tubes or uterine tubes)
- Uterus
- Vagina
Ligaments:
- Broad ligament (x2): holds the uterus and ovaries
- Round ligament (x2): extends from the uterine horns to the anterior pelvic wall
- Uterosacral ligament (x2): connects the uterus to the sacrum
- Lateral cervical (cardinal) ligaments (x2): extend from the lateral walls of the cervix to the pelvic floor
- Anterior ligament (x1): anterior cul-de-sac (ACDS) / vesicouterine pouch
- Posterior ligament (x1): posterior cul-de-sac (PCDS) / pouch of Douglas / rectouterine pouch

Ligaments Associated with the Ovaries

Mesovarium: attaches the ovary to the posterior layer of the broad ligament
Ovarian ligament: a cord-like thickening within the broad ligament, attaches the ovary to the lateral wall of the uterus
Suspensory ligament: an extension of the broad ligament, carries ovarian vessels and attaches the ovary to the pelvic wall

Ovaries and Uterine Tubes

Ovary: a small, solid, oval structure, 3 cm long, containing 250,000 primary oocytes at birth
Uterine tubes: slender tubes, about 10 cm long, located in the upper border of the broad ligament
Infundibulum: the funnel-shaped distal portion of the uterine tube, edged with fingers-like extensions called fimbriae

Basic Physiology Review

Uterine lining thickens in preparation for an embryo
Ovary releases a mature oocyte into the peritoneal cavity
The oocyte is swept into the uterine tube by fimbriae and propelled into the uterus by cilia in the uterine tubes
Fertilization usually occurs in the uterine tube, and the zygote will implant in the uterine wall for subsequent development

External Female Genitalia

Vulva (also known as pudendum): the collective term referring to all portions of the external female genitalia
Mons pubis: a subcutaneous fat pad anterior to the symphysis pubis
Labia majora: two large folds of skin filled with subcutaneous fat, located at the lateral margins of the vulva
Labia minora: two thin, delicate folds of skin located medial to the labia majora but lateral to the urethral and vaginal openings
Clitoris: located inferior to the mons pubis and between the anterior ends of the labia minora
Vestibule: a narrow cleft between the two labia minora, bordered by the clitoris at the anterior end
Urethral orifice: opens into the anterior portion of the vestibule
Vaginal orifice: opens within the vestibule, posterior to the urethra
Paraurethral and greater vestibular glands: secrete mucous for lubrication, located on either side of the urethral and vaginal orifices
