How does the muscle of the internal anal sphincter differ from that of the external anal sphincter?
The internal urethral sphincter an involuntary sphincter that keeps the urethra closed when urine is not being used. The external urethral sphincter is fashioned by skeletal muscles as the urethra passes thorugh the pelvic floor.This sphincter is voluntary controlled.

Why do you urinate when you defecate?
The primary muscles that function to hold in stool are the internal and external anal sphincters. The internal sphincter is a completely involuntary organ, and as stool passes through this sphincter, the muscle slowly relaxes. The stool then contacts the external sphincter, which is a completely voluntary organ. At this point, we sense that there is an increased pressure in our rectum, and we likely feel the need to defecate. If a toilet or other commode is close by, we sit down and voluntarily relax our external anal sphincter, and the stool passes through. If, however, we would rather not have a bowel movement at that moment, we voluntarily tighten our external anal sphincter, and the stool is retained in the rectum.
Which is the voluntary sphincter of the anal canal?

What five muscles of the pelvic outlet do males and females have in common?
bulbospongiosus, external urethral sphincter, extrernal anal sphincter, Gluteus maximus, iliococcygeus
Two anal sphincters control the flow of waste through the anal?
