How do you differentiate this from hypertonicity of the internal anal sphincter?

@gh889 I made the same mistake... fecal INCONTINENCE meaning she CAN pass stool-- in fact, way too well... more than we want. Hypertonicity of the internal anal sphincter would cause constipation-like symptoms.

But unworld says decreased function of puborectalis leads to constipation!

Exactly! That’s I didn’t pick decreased functional of puborectalis.

In the question of UW the puborectalis muscle fails to relax and in the question of NBME the puborectalis muscle fails to contract.

The puborectalis muscle, which is one of the muscles that comprise the pelvic floor and plays an important role in both fecal continence and defecation, is tonically contracted and maintains the anorectal angle at rest.
