ElastinElastin, which are stretchy, rubber-like fibers, vary in prevalence and amountthroughout skin and fascia depending upon functional demand. Elastin fiberstend to branch, creating a net-like architecture (Van den Berg 2012). Whenplaced under tensional force, these fibers lengthen and when the force isremoved they enable tissue to return to its normal, resting length. Whendehydrated, elastin becomes brittle but when well hydrated it is elastic andflexible. Elastin fibers can be stretched up to 150% their resting length withoutcausing any injury (20 to 30 times more than collagen can withstand) and likecollagen can store or release energy. When placed under sustained stretchdemand,elastin has been shown to lose some of its recoil potential.Within the tissues of the locomotor system, collagen and elastin are oftenintertwined.

Fascia Layers and Functions

Fascia taxonomy varies almost as widely as fascia itself. Which is likely why (at

least in part) at the FRC 3 in 2012, Dr Paul Standley proclaimed, ‘We need a

Rosetta Stone of manual therapy.’

In an attempt to simplify functional understanding and create a conceptual

visual, favoring relevance to MT, this book will briefly cover two of the most

current classification systems: Willard’s (2012a, 2012b) layer/structural

classification system and Kumka and Bonar’s (2012) functional classification

system.

Layer Classification

Willard (2012a) suggests four primary categories: superficial/panniculus (loose),

deep/axial (investing), meningeal and visceral (Swanson 2013). Only the

superficial and axial layers will be covered in more detail – as the techniques

covered in subsequent chapter predominantly target the superficial and deep

fascial layers. The meningeal layer will be covered (in some detail) in Chapter 4,

the visceral layer will not be covered in much detail in this book. For more

information on visceral work please see the recommended references and

reading suggestions provided at the end of the chapter.

Superficial/panniculus fascia (SF)

Although not a universally accepted term, in many textbooks superficial fascia is

used to describe the subcutaneous loose CT layer (Platzer 2008, Standring 2008,

Netter 2011, Tank 2012).

Continuous with the dermis, the SF lies directly beneath the skin, supporting the

skin’s structural integrity. Essentially, the SF surrounds the entire torso and the

extremities and mostly comprises loose CT and adipocytes.

According to Langevin and colleagues (Langevin et al. 2009), there are two

typical presentations of SF:

• Loose/areolar CT often embedded with adipocytes

• A fine mesh of dense irregular CT with areolar CT and adipocytes within the
