What is the purpose of fascia?
What is fascia? Fascia is a thin casing of connective tissue that surrounds and holds every organ, blood vessel, bone, nerve fiber and muscle in place. The tissue does more than provide internal structure; fascia has nerves that make it almost as sensitive as skin. When stressed, it tightens up.

What is a deep fascia?
Deep fascia is a relatively thick, dense, and discrete fibrous tissue layer. It acts as a base for the superficial fascia and as an enclosure for muscle groups. This layer is recognized as an off-white sheath for the underlying muscles.
What is another term for deep fascia?
Skeletal Muscle Each muscle is composed of bundles (fascicles) of myofibers surrounded by a fibrous connective tissue sheath known as the epimysium or deep fascia. Muscles are joined to tendons at myotendinous junctions. Tendons anchor each muscle to bone and are continuous with the epimysium.

What is fascia made of?
Fascia is made up of sheets of connective tissue that is found below the skin. These tissues attach, stabilize, impart strength, maintain vessel patency, separate muscles, and enclose different organs. Traditionally, the word fascia was used primarily by surgeons to describe the dissectible tissue seen in the body encasing other organs, muscles, and bones. Recently, the definition has been broadened to include all collagenous based soft tissues in the body, including cells that create and maintain the extracellular matrix. The new definition also includes certain tendons, ligaments, bursae, endomysium, perimysium, and epimysium. [1]
Why is fascia so strong?
The distinct feature of fascia is that it possesses strength because it is tightly packed with bundles of collagen and wrapped tightly. The fibers are usually oriented in one direction so that the structure does not become loose or lax. Fascia is quite flexible and able to resist tension. The function of the fascia depends on its location. [4]
What is deep fascia?
Deep fascia surrounds bones, muscles, nerves, and blood vessels. It is commonly has a more fibrous consistency and rich in hyaluronan as compared to the other subtypes. Deep fascia tends to be highly vascularized and contain well developed lymphatic channels. In some instances, deep fascia can even contain free encapsulated nerve endings, such as Ruffini and Pacinian corpuscles.
Why do surgeons suture fascia?
Following a procedure, surgeons suture superficial fascia together to ensure that there is no weakness in the wound. If the suturing is not done correctly, the sutures can tear, resulting in wound dehiscence. If the patient is malnourished, suturing the fascia together can prove much more difficult, showing the importance of adequate nutrition pre-op. Wound dehiscence is a surgical emergency, and the diagnosis is usually clinical. [6]

What is the substance that helps fascia work?
Fascia Pain. Between layers of body fascia, a substance called hyaluronan helps the layers work smoothly with each other. When the hyaluronan dries up, your body fascia can seize up around muscles, make it harder to move, or get uncomfortable knots.

Why is the neck fascia important?
This is of clinical importance as a pathway for the spread of infection. The neck fascia compartmentalises structures within the neck. These layers of tough fascia can limit the spread of infection (for example, a superficial skin abscess may be prevented from spreading deeper into the neck by the investing fascia).

What is fascia made of?
Fascia is made up of fibrous connective tissue containing closely packed bundles of collagen fibers oriented in a wavy pattern parallel to the direction of the pull. Fascia is consequently flexible and able to resist great unidirectional tension forces until the wavy pattern of fibers have been straightened out by the pulling force.
