Anal Sphincter Cutaneous

Anal Sphincter Cutaneous: Anatomical Description and Role

Cutaneous anal sphincter, also known as m. sphincter ani cutaneus, is an important structure located in the human anus. In this article we will look at the anatomy and role of this cutaneous sphincter.

Anatomical aspect:
The cutaneous anal sphincter is a circular muscle surrounding the opening of the anus. It is located in the subcutaneous tissue and consists of smooth muscle. This sphincter can be divided into internal and external components.

The internal component of the anal sphincter is a continuation of the internal anal sphincter, which consists of circular muscles. The external component is a ring of skeletal muscle that surrounds the internal component. Both components work together to control the opening of the anus and regulate the passage of stool.

The role of the cutaneous anal sphincter:
The cutaneous anal sphincter plays an important role in the functioning of the anal area and control of bowel movements. It helps maintain the tone of the anus and prevents unwanted passage of gases, fluids and stool. When the sphincter muscles contract, they squeeze the opening of the anus, creating a barrier that helps prevent unwanted discharge.

In addition, the cutaneous anal sphincter plays an important role in the process of defecation. When the desire to relieve oneself occurs, the sphincter muscles relax, allowing stool to pass through the anus and be eliminated from the body.

Diseases and disorders:
Some diseases and disorders can affect the function of the cutaneous anal sphincter. For example, the development of anal fissures or hemorrhoids can lead to discomfort and disruption of normal sphincter function. Injury, infection, or surgical procedures can also affect the function of this muscle.

Rehabilitation and treatment:
In case of dysfunction of the cutaneous anal sphincter, rehabilitation or treatment may be required. This may include conservative methods such as changes in diet and daily routine, physical therapy, or medication. In some cases, surgery may be required to restore sphincter function.

Finally:
The cutaneous anal sphincter plays an important role in the functioning of the anal area and control of bowel movements. Its anatomical structure, consisting of internal and external components, allows you to control the passage of stool and prevent the unwanted passage of gases and liquids. Disorders and diseases of this sphincter can lead to
