Fascia is a connective tissue that surrounds and supports muscles, organs, and other structures in the body. It is made up of collagen and elastin fibers, providing strength and flexibility. Fascia plays a crucial role in maintaining the structural integrity of the body and facilitating movement by allowing muscles to glide smoothly over one another. There are different types of fascia, including superficial fascia, which lies just beneath the skin, and deep fascia, which surrounds muscles and groups of muscles. Proper functioning of fascia is important for overall health, as it helps with posture, movement efficiency, and injury prevention.
