Skin HistologyThe skin comprises:• Epithelium• Connective tissue (CT).EpitheliumThere are three basic types of epithelial tissue: squamous, cuboidal and columnar– arranged in either a one-layer (simple) or multilayer (stratified) configuration.Epithelium forms many glands and lines the cavities and surfaces of structuresthroughout the body (e.g. the epidermis consists of stratified squamouskeratinizing epithelium) (Marieb et al. 2012).CTConsidered a system, CT consists of several different types of cells (e.g.fibroblasts and adipocytes), protein fibers (elastin and collagen) surrounded bythe gelatinous ECM (Schleip et al. 2012a, Andrade 2013).CT is a continuous bodywide system that plays a well-identified role inintegrating the functions of diverse cell types within each tissue it invests (e.g.skeletal muscle, tendon, bone, viscera (Langevin 2006)). CT is highly variable inits presentation. Various terms are used to describe CT typology, for example:• Dense and loose are used to describe how dense, tightly or spread out the fibersare packaged within an array of tissue• Regular, irregular, unidirectional, multidirectional, parallel ordered and wovenare used to describe fiber orientation and configuration within a particularsheet, layer or area of tissue (Terminologia Histologica 2008).

Clinical Consideration

As CT is intimately associated with other tissues and organs it may

influence the normal or pathological processes in a wide variety of organ

systems (Findley et al. 2012).

CT, fascia and the sliding mechanism

One of the more recent discoveries in the world of fascia research is the

sliding/gliding that occurs throughout the CT and fascial systems, which

facilitates unimpeded, frictionless movement (McCombe et al. 2001,

Guimberteau & Bakhach 2006, Stecco et al. 2008, Wang et al. 2009). Some

suggest that sliding layers are interspersed between CT and fascial layers;

however, Guimberteau suggests that rather than separated or superimposed

layers there exists a singular, highly hydrated, tissular architecture which can

maintain the necessary space between structures to facilitate optimal sliding and

tissue excursion (Guimberteau & Bakhach 2006, Guimberteau 2012) – see

Figure 2.2.

Whether the presentation is layers between layers or a singular architecture, the

sliding mechanism comprises loose CT – consisting of predominantly fine

collagen strands, adipocytes and an abundance of HA.

The sliding mechanism occurs bodywide on both a macro and micro level;

between interfascial planes, endofascial fibers, endomuscular fibers and

intracellular fibers (Guimberteau et al. 2005, Ingber 2008, Stecco et al. 2008,

Wang et al. 2009, Langevin 2010). The impact of traumatic scarring on the

sliding mechanism and clinical considerations will be noted throughout this

book.
