What are the boundaries of the superficial perineal pouch?

The superficial perineal pouch is contained between the perineal membrane and the deep perineal fascia. It is bounded by the inner surface of the ischiopubic ramus on each side and communicates with the potential space between the Scarpa’s fascia and the fascia of the abdominal wall muscles anteriorly.

What are each of the boundaries of the perineum?

The perineum is bounded anteriorly by the pubic arch, laterally, in a posterior direction from the lower branch of the pubis and the ischium, to the ischial tuberosity and the sacrotuberous ligament, and posteriorly ends at the apex of the coccyx.

What is the deep perineal pouch female?

The deep perineal pouch is in the urogenital triangle of the perineum below the pelvic diaphragm. It presents as a triangular, trilaminar space with sphincter urethrae [external urethral sphincter], deep transverse perineal, and compressor urethrae [in females].

What separates the superficial and deep perineal pouches?

its inferior border is the fascia of Colles, the deeper membranous layer of the superficial perineal fascia that covers the inferior border of the muscles of the superficial perineal pouch. (The fascia of perineum is a deep fascia that covers the superficial perineal muscles individually).

What are superficial perineal muscles?

The Transversus perinaei superficialis (Transversus perinaei; Superficial transverse perineal muscle) is a narrow muscular slip, which passes more or less transversely across the perineal space in front of the anus.

What are the superficial muscles of the perineum?

Introduction. The superficial pelvic floor muscles or perineal muscles are located inferior/caudal to the deep pelvic floor muscles, and comprise of external anal sphincter, transverse perinea, bulbospongiosus and ischiocavernosus muscles1,2.

What is the function of superficial 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.

Is superficial perineal pouch and space same?

The superficial perineal pouch (also superficial perineal compartment/space/sac) is a compartment of the perineum. Coronal section of anterior part of male pelvis, through the pubic arch. Seen from in front.

Which muscle is located in the superficial perineal space?

superficial transverse perinei, bulbospongiosus and ischiocavernosus). Its contents include the superficial transverse perineal muscles along with the pudendal neurovasculature, corpus spongiosum and corpora cavernosa.

On each side it is attached to the margins of pubic arch and to the deep fascia i.e. fascia lata of the of the thigh along and imaginary line extending laterally (8cm) from the pubic tubercle ( Holden’s line). What are the boundaries of superficial perineal pouch? Inferiorly: Membranous layer of superficial fascia of perineum (Colles fascia)

What is the surface marking of the perineal?

The surface marking of the perineal body lies at the midpoint of the interischial line, posterior to the posterior commissure of the vagina (posterior base of the scrotum in men) and the anus. This region is also referred to by gynaecologists as the gynaecological perineum.

What does the deep transverse perinei attach to?

Deep transverse perinei: has several attachments in the deep perineal pouch. As it spans the space in a transverse manner (albeit, incompletely), the muscle attaches to the perineal body posteriorly and the ischiopubic rami laterally.

What attaches to the posterior border of the perineal membrane?

The posterior border of perineal membrane is attached to the perineal body. The perineal membrane provides a caudal (superficial) boundary for the deep perineal pouch, which is also limited rostrally (deeply) by the endopelvic fascia of the pelvic floor. The deep perineal pouch is occupied by the pubourethralis and deep transverse perinei muscles.
