Final answer:
The sutures used for retraction are known as retraction sutures. The options provided do not accurately describe these, as they pertain to stitching methods. Additionally, 'sutures' can also refer to the fibrous joints between skull bones.
Step-by-step explanation:
The sutures placed into an anatomical structure to retract it to the side are called retraction sutures. However, from the options given, the correct answer is not listed as none of the options precisely describes sutures used for retraction.
If this is a question with provided options, please recheck the available choices or the context in which the question was asked. The terms provided – interrupted, continuous, retention, and horizontal – refer to methods of stitching a wound rather than types of sutures used for retraction.
It is essential to note that sutures of the skull, such as the fibrous joints found between the bones of the skull, are called sutures as well. These are immobile and serve to protect the brain by firmly binding the skull bones with fibrous connective tissue.
