Anatomy of the Rectus Sheath

The video tutorial explains the structure and function of the rectus sheath, a protective covering for the rectus abdominis muscle. It discusses the anterior and posterior layers of the sheath, the role of the arcuate line, and how the aponeuroses of the external oblique, internal oblique, and transverse abdominis muscles contribute to the formation of the sheath. The tutorial also highlights the differences in the sheath's composition above and below the arcuate line, emphasizing the importance of the transversalis fascia in protecting abdominal contents.
