Clinically Relevant Anatomy[edit | edit source]
The levator ani muscles as a component of pelvic floor diaphragm ( the iliococcygeus, the pubococcygeal, and the puborectalis muscles) in addition to its role as a supportive structure and keeping visceral and internal organs in place. levator ani muscles specifically puborectalis have a role to maintain the urinary and fecal continence, contraction, and relaxation of puborectalis, lower abdominal muscles, and anal sphincter work synchronically for normal and smooth defecation.
The pudendal nerve innervates the external anal sphincter and part of the puborectalis muscle, with frequent and prolonged straining that may stretch the pudendal nerve causing pudendal neuropathy.
While we have voluntary control over the external anal sphincter the internal anal sphincter muscles are involuntary muscles affected by the rectum, it is relaxed if the rectum filled with stool and vice versa, so the sensitivity of the rectum is important for normal physiology.
