Understanding the Perineum's Many Names
The perineum is the standard anatomical and medical name for the region at the bottom of the pelvic region. However, it has acquired various other names, from medical terms to slang. The central tendinous point of the perineum has a specific medical name: the perineal body.
The Formal Medical Term: Perineal Body
The perineal body (or corpus perineale) is the most accurate alternative medical name for a specific part of the perineum. This fibromuscular mass is located where the urogenital and anal triangles meet and serves as a crucial attachment point for several pelvic floor muscles. It's particularly important when discussing pelvic floor structure and potential damage during childbirth.
Common Informal and Slang Names
Informally, the perineum is known by several slang names. While widespread, these are not suitable for clinical settings. Common terms include:
- Taint: A common slang term.
- Gooch: Another American slang term.
- Grundle: Another colloquial name with uncertain origins.
These terms are part of casual conversation but lack anatomical precision.
Anatomical Structure and Subdivisions
The perineum is a diamond-shaped region defined by pelvic bony landmarks. An imaginary line between the ischial tuberosities divides it into two triangles:
- The Urogenital Triangle: The front triangle containing the external genitalia and openings for the urethra and vagina or penis and scrotum. It's supported by the perineal membrane.
- The Anal Triangle: The rear triangle containing the anus, supported by the external anal sphincter and ischioanal fossae.
Muscles and Support
The perineal body is central to both triangles and is where several pelvic floor muscles, including the bulbospongiosus, external anal sphincter, and transverse perineal muscles, attach. This muscle network is vital for pelvic floor stability, supporting organs, and controlling continence.
The Function and Importance of the Perineum
The perineum is a sensitive area with vital functions:
- Pelvic Floor Support: It supports pelvic organs like the bladder, uterus, and rectum.
- Sexual Function: Its nerve endings make it an erogenous zone.
- Continence: Muscles attached to the perineal body help control urination and defecation.
- Childbirth: The perineum stretches significantly during vaginal delivery, and its health affects recovery.
Comparison of Terms: Perineum vs. Perineal Body
| Feature | Perineum | Perineal Body |
|---|---|---|
| Definition | The entire diamond-shaped surface region between the anus and genitals. | A specific fibromuscular mass located at the center of the perineum. |
| Function | Provides overall support and contains various structures. | Serves as a central attachment point for key pelvic floor muscles. |
| Scope | A broad anatomical region encompassing multiple structures. | A specific, smaller structure within the larger perineum. |
| Context | Used to describe the general area and is the most common formal term. | A more precise medical term used to describe a specific anatomical feature. |
| Location | The entire surface at the pelvic outlet, from the pubic arch to the coccyx. | Centered between the anal canal and the urogenital structures. |
Clinical Significance and Care
Perineal health is clinically important. Childbirth injuries can lead to issues like prolapse or incontinence if not managed. Strengthening pelvic floor muscles through exercises like Kegels can improve function. Good hygiene is also essential for this sensitive region.

Conclusion
So, what is another name for the perineum? The most accurate medical alternative for the central point is the perineal body, while informal terms like 'taint' are common. This vital area supports the pelvic floor, controls continence, and contributes to sexual health. Understanding its various names helps in both medical and casual contexts, highlighting the importance of this often-overlooked body part.
