Overview

The neuroanatomy of the pelvis underpins motor and sensory function of the lower limb, perineum and pelvic organs. This section introduces the sacral plexus and pudendal nerve and outlines their major branches and distributions. These pathways are central to continence, sexual function and lower limb movement.

Key Structures

Topics include the sacral plexus, with its major motor and sensory branches, and the pudendal nerve, which supplies the perineum and pelvic floor. Anatomical relationships and typical variations are also discussed.

Clinical Relevance and Learning Focus

A strong understanding of pelvic nerve pathways is essential for assessing pelvic pain, nerve entrapment, childbirth-related injury and incontinence. This section supports regional anaesthesia, surgical planning and neurological assessment.
