At which positions are haemorrhoids typically found?

Haemorrhoids, particularly the internal type, are typically found in the anal canal and have classic positions based on the anatomy of the lower rectum. The anatomical locations of haemorrhoids correspond to specific positions around an imaginary clock face when considering the anal opening.

The correct choice, detailing the 3, 7, and 11 o'clock positions, aligns with the typical locations of the superior rectal veins, which can give rise to internal haemorrhoids. These positions are typically where the most vascular areas of the anal canal are located, as the superior rectal veins create the cushions of the anal canal that can become engorged or swollen, leading to the formation of haemorrhoids.

In clinical practice, recognizing these positions is crucial for diagnosis and treatment, as they guide interventions that may be necessary to manage haemorrhoids.

Positions involving the 1, 5, and 9 o'clock orientation are less commonly associated with typical internal haemorrhoid development, and likewise, the other options (2, 8, and 10, or 12, 3, and 6) do not accurately reflect the standard anatomical understanding of where these vascular cushions can yield haemorrhoids
