Arcuate Line of Rectus Sheath
The Arcuate Line of Rectus Sheath (pronunciation: /ɑːrˈkjuːeɪt laɪn ɒv ˈrɛktəs ʃiːθ/) is a horizontal line that marks the lower limit of the posterior layer of the Rectus Sheath. It is an important anatomical landmark in the abdominal region.
Etymology
The term "Arcuate" is derived from the Latin word 'arcuatus' which means 'bowed' or 'arched'. The term "Rectus" is derived from the Latin word 'rectus' which means 'straight'. The term "Sheath" is derived from the Old English word 'sceath' which means 'a case for a blade'.
Anatomy
The Arcuate Line of Rectus Sheath is located approximately midway between the umbilicus and the pubic symphysis. Above this line, the Rectus Sheath is composed of the aponeuroses of the external oblique, internal oblique, and transversus abdominis muscles. Below this line, all three aponeuroses pass anterior to the rectus abdominis, leaving only the transversalis fascia posteriorly.
Clinical Significance
The Arcuate Line of Rectus Sheath is a significant landmark in abdominal surgeries, particularly in procedures involving the lower abdomen and pelvis. It is also important in the diagnosis and treatment of hernias.
