Sometimes the peritoneum completely invests it and forms a distinct but narrow mesocolon. It is in relation, in front, with the convolutions of the ileum and the abdominal walls. Parasympathetic innervation to the ascending colon is supplied by the vagus nerve. Sympathetic innervation is supplied by the thoracic splanchnic nerves.

Hemorrhoid cushions are a part of normal human anatomy and become a pathological disease only when they experience abnormal changes. There are three main cushions present in the normal anal canal. Sinusoids do not have muscle tissue in their walls, as veins do. This set of blood vessels is known as the hemorrhoidal plexus. Hemorrhoid cushions are important for continence. Hemorrhoids are typically diagnosed by physical examination.

A visual examination of the anus and surrounding area may diagnose external or prolapsed hemorrhoids. Internal hemorrhoids originate above the dentate line. They are covered by columnar epithelium, which lacks pain receptors. Grade IV: Prolapse with inability to be manually reduced. External hemorrhoids occur below the dentate or pectinate line. They are covered proximally by anoderm and distally by skin, both of which are sensitive to pain and temperature. Many anorectal problems, including fissures, fistulae, abscesses, colorectal cancer, rectal varices, and itching have similar symptoms and may be incorrectly referred to as hemorrhoids. Other conditions that produce an anal mass include skin tags, anal warts, rectal prolapse, polyps, and enlarged anal papillae.
