The Pelvis

Overview

The pelvis forms the transition between the trunk and lower limbs, providing support for abdominal organs and housing the reproductive and urinary systems. This section explores the skeletal framework, muscular structures and compartments of the pelvis and perineum. It establishes a foundation for understanding pelvic function, stability and clinical relevance in surgical and obstetric practice.

Key Structures

Topics cover the bony pelvis, pelvic joints and ligaments, as well as the musculature of the pelvic floor and walls. The anatomy of the bladder, rectum and reproductive organs is described alongside the associated vessels and nerves. The section provides diagrams and explanations that clarify complex spatial relationships within this confined anatomical region.

Clinical Relevance and Learning Focus

Knowledge of pelvic anatomy is critical for gynaecological, urological and colorectal practice. The content connects anatomical structures to clinical procedures such as pelvic examination, childbirth and surgical dissection, ensuring learners gain both theoretical and applied understanding of the region.
