Muscles of the Pelvis

Overview

The pelvic floor forms a dynamic muscular diaphragm that supports pelvic organs, assists in continence and contributes to core stability. This section introduces the major muscles forming the pelvic diaphragm and urogenital structures. These muscles play an important role in respiration, load transfer and functional movement.

Key Structures

Topics cover the layered musculature of the pelvic floor, including levator ani and coccygeus, their fascial support, and their integration with adjacent pelvic and abdominal structures. Detailed descriptions emphasise attachments, nerve supply and functional coordination.

Clinical Relevance and Learning Focus

A clear understanding of pelvic floor anatomy is essential for managing prolapse, incontinence, pelvic pain and postpartum dysfunction. This section also supports clinical assessment and targeted rehabilitation strategies in both men and women.
