  2. Perineum - Wikipedia

    en.wikipedia.org/wiki/Perineum

    The perineal body (or central tendon of perineum) is a pyramidal fibromuscular mass in the middle line of the perineum at the junction between the urogenital triangle and the anal triangle. In males, it is found between the bulb of the penis and the anus ; in females, it is found between the vagina and anus, and about 1.25 cm (0.49 in) in front ...

  3. Urogenital triangle - Wikipedia

    en.wikipedia.org/wiki/Urogenital_triangle

    As might be expected, the contents of the urogenital triangle differ greatly between the male and the female. Some of the components include: [1] Posterior scrotal nerves / posterior labial nerves; Urethra; Vagina; Bulbourethral gland / Bartholin's gland; Muscles Superficial transverse perineal muscle; Ischiocavernosus muscle; Bulbospongiosus ...

  4. Transverse perineal muscles - Wikipedia

    en.wikipedia.org/wiki/Transverse_perineal_muscles

    The function of the muscle is fixation of the perineal body (central tendon of perineum), support of the pelvic floor, expulsion of semen in males and last drops of urine in both sexes. [2] The deep transverse perineal muscle lies in the same plane as the urethral sphincter and formerly the two muscles were described together as the constrictor ...

  5. Bulbospongiosus muscle - Wikipedia

    en.wikipedia.org/wiki/Bulbospongiosus_muscle

    The bulbospongiosus muscles (in older texts bulbocavernosus and, for female muscle, constrictor cunni) are a subgroup of the superficial muscles of the perineum. [1] They have a slightly different origin, insertion and function in males and females. In males, these muscles cover the bulb of the penis, while in females, they cover the vestibular ...

  6. Vaginal support structures - Wikipedia

    en.wikipedia.org/wiki/Vaginal_support_structures

    The perineum attaches across the gap between the inferior pubic rami bilaterally and the perineal body. This grouping of muscles constricts to close the urogenital openings. The perineum supports and functions as a sphincter at the opening of the vagina. Other structures exist below the perineum that support the anus. [3] [6]
