Updhatus are important physiological units and are derived from Dhatus and resemble Dhatus in terms of structure, function and nature. Dhatus are the seven basic fundamental principles that support the basic structure which hold the bodily elements together and the functioning of the body. Meda dhatu is fourth among seven dhatus. During the process of metabolism and formation of Meda Dhatu, ligaments (snayu) are formed as metabolic byproducts (upadhatu). Snayu is the most important structure of the human body which helps to maintain the weight carrying capacity of the joint and plays a crucial role during the movement of the joint. The Snayu is much similar to the ligament. Any injury to the ligament is known as a sprain. Sprain is most common in sportsmen and hard workers. Common ligamental injuries are to the knee, ankle, wrist, thumb, neck or back ligament with ankle injury being the most commonly occurring injury. So, the complete knowledge of snayu very essential to prevent such injuries and certain disease conditions.
