  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. Perineal membrane - Wikipedia

    en.wikipedia.org/wiki/Perineal_membrane

    The perineal membrane is an anatomical term for a fibrous membrane in the perineum. The term "inferior fascia of urogenital diaphragm", used in older texts, is considered equivalent to the perineal membrane. It is the superior border of the superficial perineal pouch, and the inferior border of the deep perineal pouch.

  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. Perineal raphe - Wikipedia

    en.wikipedia.org/wiki/Perineal_raphe

    The perineal raphe is a visible line or ridge of tissue on the body that extends from the anus through the perineum to the scrotum (male) or the vulva (female). It is found in both males and females, arises from the fusion of the urogenital folds, and is visible running medial through anteroposterior, to the anus where it resolves in a small knot of skin of varying size.

  6. Bulbospongiosus muscle - Wikipedia

    en.wikipedia.org/wiki/Bulbospongiosus_muscle

    In females, there is no union, nor a tendinous perineal raphe; the parts are disjoint primarily and arise from the same central tendinous point of the perineum, which is the tendon that is formed at the point where the bulbospongiosus muscle, superficial transverse perineal muscle, and external anal sphincter muscle converge to form this major ...

  7. Fascia of perineum - Wikipedia

    en.wikipedia.org/wiki/Fascia_of_perineum

    The fascia of perineum (deep perineal fascia, superficial investing fascia of perineum or Gallaudet fascia) is the fascia which covers the muscles of the superficial perineal pouch. The muscles surrounded by the deep perineal fascia are the bulbospongiosus , ischiocavernosus , and superficial transverse perineal .

  8. Deep perineal pouch - Wikipedia

    en.wikipedia.org/wiki/Deep_perineal_pouch

    The deep perineal pouch is bordered inferiorly by the perineal membrane, also known as the inferior fascia of the urogenital diaphragm. It is bordered superiorly by the superior fascia of the urogenital diaphragm. [1] The deep pouch is now described as the region between the perineal membrane and the pelvic diaphragm. [2]

  9. Urogenital triangle - Wikipedia

    en.wikipedia.org/wiki/Urogenital_triangle

    The urogenital triangle is the anterior part of the perineum. In female mammals, it contains the vulva, ... Muscular perineal body; Superficial and deep perineal pouch;
