The abdominal wall is a structure that encases the abdominal cavity, providing support and protection for the internal organs. It consists of layers of muscles, connective tissue, and skin, which work together to maintain posture and assist in movements such as bending and twisting. The main muscles include the rectus abdominis, external obliques, and internal obliques. In addition to its protective role, the abdominal wall plays a crucial part in various bodily functions, including respiration and digestion. It helps in actions like coughing and sneezing by increasing intra-abdominal pressure. Proper strength and flexibility of the abdominal wall are important for overall physical health and injury prevention.
