External sphincter muscle
External Sphincter Muscle
The External Sphincter Muscle is a circular muscle that helps control excretion in the body. It is part of the Urinary System and the Digestive System, and is found in both males and females.
Anatomy[edit | edit source]
The External Sphincter Muscle is composed of striated muscle tissue, which allows for voluntary control over urination and defecation. It surrounds the Urethra in both sexes, and the Anus in the digestive system.
Function[edit | edit source]
The primary function of the External Sphincter Muscle is to control the release of substances from the body. It does this by contracting to close off the urethra or anus, and relaxing to allow substances to pass through.
Clinical Significance[edit | edit source]
Damage or dysfunction of the External Sphincter Muscle can lead to incontinence, a condition where an individual is unable to control their urination or defecation. This can be caused by a variety of factors, including aging, childbirth, and certain neurological conditions.
