Anatomy: The pelvic diaphragm is composed of two main muscles: the levator ani and the coccygeus. The levator ani muscle is further divided into three parts:
- Pubococcygeus: This muscle extends from the pubic bone to the coccyx (tailbone) and forms the anterior part of the levator ani. It supports the bladder and the urethra in both men and women and helps maintain urinary continence. In women, it also supports the vagina.
- Iliococcygeus: This muscle extends from the ischial spine (a bony projection on the pelvis) to the coccyx and forms the middle part of the levator ani. It provides support to the pelvic organs and helps maintain fecal continence.
- Puborectalis: This muscle forms a sling around the rectum, pulling it forward and maintaining an angle between the rectum and the anal canal. This helps maintain fecal continence by keeping the anal canal closed at rest.
The coccygeus muscle extends from the ischial spine to the coccyx and sacrum (the triangular bone at the base of the spine) and forms the posterior part of the pelvic diaphragm. It assists in supporting the pelvic organs and stabilizing the sacroiliac joint.
- Functional roles:
- Support: The pelvic diaphragm muscles provide a supportive hammock for the pelvic organs, preventing them from descending or prolapsing. They also help maintain the correct positioning of the organs, which is essential for their normal function.
- Continence: The pelvic diaphragm muscles work in coordination with the sphincter muscles to maintain urinary and fecal continence. They contract during activities that increase abdominal pressure, such as coughing, sneezing, or lifting, to prevent leakage. In women, the pelvic diaphragm muscles also help maintain the closure of the vagina.
- Sexual function: The pelvic diaphragm muscles, particularly the pubococcygeus muscle, play a role in sexual function. They contract during sexual arousal, contributing to the sensation of sexual pleasure. In men, they also help control ejaculation.
- Stability: The pelvic diaphragm muscles work together with the abdominal, back, and hip muscles to provide stability and control to the pelvis and lower spine during movement and physical activities. They help maintain proper posture and alignment, absorb shock during impact activities, and contribute to overall core stability.
- Dysfunction: Pelvic diaphragm dysfunction can occur due to various factors, such as childbirth, aging, surgery, injury, or neurological conditions. Dysfunction can lead to issues such as pelvic organ prolapse, urinary or fecal incontinence, sexual dysfunction, and chronic pelvic pain. Treatment for pelvic diaphragm dysfunction may include pelvic floor physical therapy, behavioral modifications, medication, or surgery, depending on the underlying cause and severity of the symptoms.
Medicivils Medical Science Optional Test Series: Better Than UPSC Medico? Introduction The UPSC Civil Services Examination (CSE) is one of the most competitive exams in the world. The Medical Science optional is a popular choice for many candidates, as it covers a wide range of topics that are relevant to the UPSC syllabus.

Quality of Questions The quality of the questions in the Medicivils test series is very high. The questions are well-drafted and cover a wide range of topics from the syllabus.
