Anatomy, Abdomen and Pelvis: Abdominal Wall

Excerpt

The abdomen describes a portion of the trunk connecting the thorax and pelvis. An abdominal wall formed of skin, fascia, and muscle encases the abdominal cavity and viscera. The abdominal wall does not only contain and protect the intra-abdominal organs but can distend, generate intrabdominal pressure, and move the vertebral column. Detailed knowledge of the components of the abdominal wall is essential for surgeons both in understanding the pathology affecting it and planning surgical access to the abdominal cavity. Abdominal wall defects may be either congenital or acquired and can have a significant impact on patients’ quality of life.
