How do the arms of a West retractor differ from those of a Weislander retractor?

The correct choice highlights the distinctive design of the arms of a Weislander retractor compared to a West retractor. The arms of a Weislander retractor curve outwardly, allowing for a wider separation of tissue during surgical procedures. This outward curvature is essential for holding back larger sections of tissue or organs while providing optimal visibility and access to the surgical field.

In contrast, the arms of the West retractor typically have a different curvature that does not facilitate this same outward spread, which makes it more suitable for specific types of surgeries where less exposure is needed. Understanding the anatomy and design purpose of these retractors is crucial for proper selection during surgery, as it can affect the efficiency and effectiveness of the procedure.
