What is a Tendon?

Tendons are strong fibrous bands of connective tissue that link muscle to bone. They are responsible for transmitting the force generated by muscle contraction to move the bones and generate motion in the body. The word “tendon” is derived from the Latin word “tendo” which means “to stretch”. Tendons are commonly found in the arms, shoulders, legs, and back, but can also be found around many other joints in the body.

The Structure of TENDON

Tendons are made up of a tissue known as connective tissue which is composed mostly of collagen. Collagen is a type of protein that is able to form long, strong fibers. These fibers form the foundation of a tendon and can withstand great forces. Tendons are also composed of smaller amounts of elastin, a protein that allows the structures to stretch, and proteoglycans, a carbohydrate molecule which helps to bind them together.

The Function of TENDON

The primary function of tendons is to transmit tension and generate motion. When muscles contract, they pull on the tendon, which then pull on the bones and the joints they are connected to, causing the body to move. Tendons are also responsible for stabilizing the joints by reducing the movement of the bones and providing balance while walking or running.

In addition to their role in generating motion, tendons also play a role in transmitting loads from the body to the ground. When someone is carrying a heavy load, the tendons in their legs and back help to bear the load and keep the body upright. Similarly, tendons in the neck and back help to maintain posture and can improve balance.

Conclusion

Tendons are strong, fibrous bands of connective tissue that link muscle to bones. They are composed of mostly collagen, elastin, and proteoglycans and are responsible for transmitting the force generated by muscle contraction to cause movement in the body. They also help to bear and transfer loads, as well as stabilize the joints and maintain posture and balance.
