What is retinaculi?

Retinacula is a term used to describe bands or thickened structures that hold tendons or muscles in place. They are found throughout the human body, especially in the extremities such as the hands and feet. There are several retinacula in our body including the extensor retinaculum which is located on the wrist and the flexor retinaculum which is located on the ankle. The retinacula act like a sheath and hold the tendons in place as they travel through the body. When these structures are damaged or ruptured, it can cause severe pain and limited mobility. Retinacula are an important part of our body's functioning, and help to ensure that our muscles and tendons are properly aligned and working together efficiently.
