Lesson Transcript
Instructor: Artem Cheprasov
Fibers, fascia, and tendons: they're all part of our muscles, and they are all unfortunately affected by problems large and small. They're involved in fasciitis, fibromyalgia, tenodynia, and tendinitis.

Body Layers

Who loves cake? I do! Layered cakes are some of the best. They have all sorts of colorful, tasty cream sections separated, covered, or bound by thin layers of sponge cake. These layers, and the supporting thin layers of sponge cake in between them, are reminiscent of a part of your body that's rarely heard of. It helps support the muscles of your body.

This lesson will define this structure, as well as other terms that are related to the problems that can affect the fibers, fascia, and tendons of your muscles!

Fascia & Fasciitis

But let's go back to the cake for a second. Those layers of dough in between the different layers of cream and other filling remind me of fascia, which is connective tissue that covers, separates, supports, or binds muscles, various organs and tissues, or their layers.

As you can tell by the image on the screen, this fascia is found in many different parts of your body, and like that dough in the cake, it helps to separate and support different tissues in your body. This fascia can have some unfashionable problems, like fasciitis, or the inflammation of fascia, where the suffix of '-itis' stands for 'inflammation.'

Fascia is located throughout the body, providing support and strength.

Fibers & Fibromyalgia

As the definition of fascia kind of made clear, muscles are enveloped in and separated by fascia. Our muscles are made up of muscle fibers. When you're chowing down and ripping apart that beef jerky, you're eating a bunch of muscle fibers, or muscle cells.

People who have chronic fibromyalgia are known to have atrophied muscle fibers. Atrophy means something is decreased in size compared to the norm. Fibromyalgia is a disorder characterized by widespread muscle pain and fatigue, among other signs and symptoms, like joint or bone pain.

This word comes from 'fibr/o,' which implies 'fibrous tissue;' 'my/o,' which means 'muscle;' and '-algia,' which means 'pain.' I don't know if this will help you, but I remember that 'my/o' means 'muscle' because 'myo-' rhymes with 'Mayo,' as in Cinco de Mayo, where all sorts of delicious meat is served. And I remember that '-algia' means pain by imagining some algae writhing in pain. Weird, yes, but you don't remember the mundane stuff nearly as well!

Tendons & Tendinitis

The tendons, the fibrous tissues that connects muscle to bone, can also be affected by problems. Maybe you even have had one of these, called tendinitis, the inflammation of a tendon. Tendinitis is sometimes spelled alternatively as tendonitis.
