fascia
a band or sheet of fibrous connective tissue that covers, supports, and separates muscle
Fascia is a thin layer of connective tissue present throughout the human body that surrounds and separates muscles, organs, and other structures within the body. It provides structural support and helps to distribute tension and force created by movement and other activities.
Fascia is made up of a fibrous matrix of collagen and elastin fibers, which give it strength and flexibility. It also has a network of blood and lymph vessels, nerves, and other structures running through it.
Fascia is divided into three main layers: superficial fascia, deep fascia, and visceral fascia. Superficial fascia is the layer closest to the skin and contains fat cells and blood vessels. Deep fascia is the layer that surrounds muscles and other structures, providing support and protection. Visceral fascia is the layer surrounding organs in the abdominal and thoracic cavities.
Fascia can become stiff and restricted due to injury, inflammation, or poor posture, which can lead to pain, decreased range of motion, and muscle dysfunction. Techniques such as myofascial release and foam rolling can be used to help release tension and improve fascial health and mobility.
