With regards to the anorectal angle, what is true
Answer- A. It distributes intraabdominal forces onto the pelvic floor and plays and impoant role in continence mechanismAt rest the puborectalis muscle creates a 'sling' around the distal rectum, forming a relatively acute angle (Anorectal angle).It is 90 to 100 degrees at rest.Both the internal and external sphincters are innervated by pudendal nerve.

It is due to the pull of the external sphincter
It is around 30 degrees at trest
The angle increases at the time of defecation
