Anterior abdominal wall
Anterior Abdominal Wall
The Anterior Abdominal Wall (pronunciation: an-teer-ee-or ab-dom-in-al wall) is a significant anatomical structure in the human body. It is the front part of the abdominal wall, which is a sheet of muscles and fascia that protect the abdominal organs.
Etymology
The term "Anterior Abdominal Wall" is derived from the Latin words "anterior" meaning front, and "abdomen" which refers to the region of the body between the thorax and pelvis.
Structure
The Anterior Abdominal Wall is composed of several layers, including skin, fascia, muscles, and peritoneum. The muscles include the Rectus Abdominis, External Oblique, Internal Oblique, and Transversus Abdominis. These muscles are responsible for various movements of the trunk and maintain the integrity of the abdominal cavity.
Function
The primary function of the Anterior Abdominal Wall is to protect the internal organs of the abdomen, including the stomach, liver, spleen, pancreas, and intestines. It also plays a crucial role in respiration, urination, defecation, and childbirth by increasing intra-abdominal pressure.
