What does PCL mean in Physiology?

Posterior cruciate ligament

The posterior cruciate ligament is one of the four major ligaments of the knee. It connects the posterior intercondylar area of the tibia to the medial condyle of the femur. This configuration allows the PCL to resist forces pushing the tibia posteriorly relative to the femur. In the quadruped stifle, based on its anatomical position, it is referred to as the caudal cruciate ligament. The PCL is an intracapsular ligament along with the anterior cruciate ligament because it lies deep within the knee joint. They are both isolated from the fluid-filled synovial cavity, with the synovial membrane wrapped around them. The PCL gets its name by attaching to the posterior portion of the tibia.
