Anorectal Angle
The anorectal angle is the angle formed between the rectum and the anal canal. It plays a crucial role in maintaining continence, as it helps to prevent the involuntary passage of stool. This angle is typically around 90 degrees in a healthy individual and can change during activities such as defecation.
The anorectal angle is influenced by various factors, including the position of the body during bowel movements. For instance, squatting can alter this angle, potentially making it easier to pass stool. Understanding the anorectal angle is important in fields like gastroenterology and colorectal surgery.
