What does urogenital diaphragm contain?
The urogenital diaphragm consists of the deep transverse perineal muscle with the superior and inferior fascia. The superficial trigonal muscle is composed of the bulbocavernosus, ischiocavernosus, and superficial transverse perineal muscles in the anterior triangle and the anal sphincter in the posterior triangle.
Is urogenital diaphragm and pelvic diaphragm same?
The urogenital diaphragm, also called the triangular ligament, is a strong, muscular membrane that occupies the area between the symphysis pubis and ischial tuberosities and stretches across the triangular anterior portion of the pelvic outlet. The urogenital diaphragm is external and inferior to the pelvic diaphragm.
Which muscle is part of the urogenital diaphragm and constricts the urethra?

Is urogenital diaphragm the same as 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. The deep pouch is now described as the region between the perineal membrane and the pelvic diaphragm.
What muscle controls the urethral sphincter?
A layer of muscle called the urogenital diaphragm supplies support for the contents of the pelvis and acts as the external urethral sphincter. It provides a second means of stopping the escape of urine from the body. This sphincter is under voluntary control.
What happens when you strengthen your pelvic floor?

How do you strengthen your external urethral sphincter?
How to perform kegel exercises
- Sit on the toilet and start to urinate.
- Try to stop the flow of urine midstream by contracting your pelvic floor muscles.
- Repeat this action several times until you become familiar with the feel of contracting the correct group of muscles.
- This method of contraction is a kegel exercise.
How many sphincters are in the male urinary system?
Males have two sphincters: Bladder internal/neck sphincter, smooth muscle is continuous with the detrusor muscle and is under involuntary control or autonomic control; the function of this sphincter is to keep the bladder closed at the time of ejaculation.
Where is the external urethral sphincter located in males?
In males, the external urethral sphincter is located at the same level as the membranous urethra and is composed of circular muscle fibers. The external urethral sphincter is continuous with the isthmus of the prostate.
Can a damaged urethra heal itself?
