What are the muscles of perineal body?

What are the muscles of perineal body?

The muscular branches innervate the superficial transverse of the perineum, the bulbocavernosus, the ischiocavernosus, the deep transverse muscle of the perineum, the sphincter of the urethra and the anterior portion of the external anal sphincter and the levator anis muscle.

Which is attached to the perineal body?

The perineal body is attached to the vaginal introitus, as well as the posterior commissure labia majora. In addition to the other muscles of the deep perineal pouch, females also have the urethrovaginalis muscle that surrounds both the urethral and vaginal orifices.

What is perineal body and its importance?

The perineal body is essential for the integrity of the pelvic floor, particularly in females. Its rupture during vaginal birth leads to widening of the gap between the anterior free borders of levator ani muscle of both sides, thus predisposing the woman to prolapse of the uterus, rectum, or even the urinary bladder.

What is perineum in anatomy?

The perineum is an area located at the lowermost aspect of the pelvis just inferior to its floor and between the thighs. It is diamond-shaped and can be divided by an imaginary line drawn between the two ischial tuberosities, into an anterior urogenital triangle and a posterior anal triangle.

What are deep transverse perineal muscles?

The deep transverse perenei are muscles of the pelvic diaphragm running transversely across the pelvic floor. They act to support the pelvic viscera and support the perineal body. The deep transverse perinei are innervated by the perineal branch of the pudendal nerve (S2-S4).

What are the muscles that make up the perineum?

The perineal body marks the point of convergence of the bulbospongiosus muscles, superficial and deep transverse perinei, perineal membrane, external anal sphincter, posterior vaginal muscularis, and the insertion of the puborectalis and pubococcygeus muscles.

Where is the perineal body located in the human body?

The perineal body is a midline structure formed by dense connective tissue. It anchors the perineal membrane as well as provides attachment to several perineal muscles: It is located between the penile bulb and the anus in males while in females it lies between the vagina and external anal sphincter.

Where is the urogenital triangle located in the female perineum?

In a sagittal view, the urogenital triangle faces anteriorly and downward and the anal triangle faces posteriorly and upward (Fig 2). The perineum contains the distal two-thirds of the urethra, the distal vagina at the level of the introitus, and the anal canal. Figure 1 Illustration of the muscles of the female perineum in the axial view.

Where is the central tendon of the perineum located?

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. It is found in both males and females.
