Muscles of the Abdomen

Overview

The muscles of the abdominal wall support posture, respiratory movement and protection of abdominal organs. This section introduces the major muscle groups of the anterolateral and posterior abdominal walls.

Key Structures

Topics include the anterolateral abdominal wall, with its layered musculature and fascial planes, and the posterior abdominal wall, which contributes to trunk stability and movement.

Clinical Relevance and Learning Focus

Knowledge of abdominal wall anatomy assists in evaluating hernias, abdominal pain, surgical incisions and core stability. It underpins procedures such as laparoscopic entry and regional anaesthesia.
