Fissures

The term fissure (as used in anatomy) refers to the deep grooves, clefts, tears, or furrows that exist on various parts of the human body. It can also refer to a cleft between one body part or organ and another. In the brain a fissure (the indentation that causes the folded appearance) is called a sulcus. Fissures are commonly experienced in the anus and are usually short-term problems and react positively to home treatment.
