| pars annularis vaginae fibrosae | One of the two circular fibrous bands of the fibrous sheaths of the fingers and toes attached to the shaft of the proximal and middle phalanges. Synonym: pars annularis vaginae fibrosae, annular pulley, annulus of fibrous sheath, ligamentum annulare digitorum. (05 Mar 2000) |

| pars cruciformis vaginae fibrosae | The fibres of the fibrous sheath of the fingers and toes which form X-shaped patterns over the region of the interphalangeal joints. Synonym: pars cruciformis vaginae fibrosae, crucial ligament, cruciform part of fibrous sheath, cruciform pulley, ligamenta cruciata digitorum. (05 Mar 2000) |
| vestibulum vaginae | The space behind the glans clitoridis and between the labia minora, containing the openings of the vagina, urethra, and ducts of the greater vestibular glands. Synonym: vestibulum vaginae, vaginal introitus, vestibulum pudendi. (05 Mar 2000) |
| pars lateralis fornicis vaginae | pars lateralis fornicis vaginae |
| pars posterior fornicis vaginae | The recess at the vault of the vagina; it is divided into an anterior part, posterior part, and lateral part with respect to its relation to the cervix of the uterus. The posterior part is clinically significant as the site for culdocentesis and culdoscopy. The proximity of the ureter (below) and the uterine artery (above) adjacent to the lateral fornix is important clinically. Synonym: fornix vaginae, fornix uteri. (05 Mar 2000) |
| musculus sphincter vaginae | <anatomy> In the male: origin, the perineal membrane fascia on the dorsum of the bulb of the penis; insertion, central tendon of the perineum and the median raphe on the free surface of the bulb; action, constricts bulbous urethra when attempting to expel last drops following urination, or spasmodically with ejaculation to expel semen. In the female: origin, the dorsum of the clitoris, the corpus cavernosum, and the perineal membrane; insertion, central tendon of the perineum; action, acts as a weak sphincter of the vagina; when developed, is a part of "cross-member musculature" of pelvic floor which resists prolapse of pelvic viscera. Nerve supply, pudendal (deep perineal branch). Synonym: musculus bulbospongiosus, musculus bulbocavernosus, musculus ejaculator seminis, musculus sphincter vaginae, sphincter vaginae. (05 Mar 2000) |

| orificium vaginae | The narrowest portion of the canal, in the floor of the vestibule posterior to the urethral orifice. Synonym: ostium vaginae, orificium vaginae, vaginal opening. (05 Mar 2000) |
| ostium vaginae | The narrowest portion of the canal, in the floor of the vestibule posterior to the urethral orifice. Synonym: ostium vaginae, orificium vaginae, vaginal opening. (05 Mar 2000) |
| tunica mucosa vaginae | The mucous membrane of the vagina. Synonym: tunica mucosa vaginae. (05 Mar 2000) |
| tunica muscularis vaginae | Muscular layer of the vaginal wall. Synonym: tunica muscularis vaginae. (05 Mar 2000) |
| lamina posterior vaginae musculi recti abdominis | The portion of the sheath of the rectus abdominis muscle that lies posterior to the muscle covering only its upper two-thirds; it is formed by contributions from the aponeuroses of the internal oblique and transversus abdominis muscles; its free inferior margin forms the arcuate line; it is deficient below this, the posterior aspect of the muscle being covered only by transversalis fascia and peritoneum. Synonym: lamina posterior vaginae musculi recti abdominis. (05 Mar 2000) |

| fossa navicularis vestibulae vaginae | The portion of the vestibule of the vagina between the frenulum of the labia minora and the posterior labial commissure of the vulva. Synonym: fossa vestibuli vaginae, fossa navicularis vestibulae vaginae, vestibular fossa. (05 Mar 2000) |
| fossa vestibuli vaginae | The portion of the vestibule of the vagina between the frenulum of the labia minora and the posterior labial commissure of the vulva. Synonym: fossa vestibuli vaginae, fossa navicularis vestibulae vaginae, vestibular fossa. (05 Mar 2000) |
