My goal: Utilize images to inform the student of the complex structural system of fascia. Your goal?
Historical Definition Fascia: general description, a band of tissue. General meaning: undifferentiated tissue surrounding a more specialized tissue. LANGEVIN, MD, H., HUIJING, PHD, P..

Gross Anatomy Photography of anatomical structures: What is it? What do we learn?
"Old-School" Histology Gradations of pink, some purples, blues: Procedures: Create a specimen Mount on slides Put drops of solutions on slide for specific period of time. Rinse & mount. Put in a slide box.
"Old-School" Histology Put in a slide box.
What do we learn from histology? Highlights & differentiates: Cells, fibers & tissues Gives insight into cellular structures.
Histology of Connective Tissue types: Dense Irregular Abundant Collagen fibers, few cells. What type of tissues?
Histology of Connective Tissue types: Dense Regular Abundant Collagen fibers, arranged in same direction, f few cells. What type of tissues?
Histology of Connective Tissue types: Areolar Sparsely arranged fibers, not ordered in a predominant direction. Oftern refferd to as "Loose" but Dr. Langevin suggests this label is too mechanical in description
Specialized Fascial Structures: Superficial Fascia: aka: hypoderm, hypodermis, stratum subcutaneous, etc. Continuous with the dermis, directly underneath the skin
Specialized Fascial Structures: Deep Fascia
Specialized Fascial Structures: Muscular Fascial layers: Endo Peri Epi
Specialized Fascial Structures: Intermuscular Septa
Specialized Fascial Structures: Neurovascular Tract
Specialized Fascial Structures: Periosteum
How did histology help us differentiate: Regular vs. Irregular Fiber Arrangements Layers of fascia Structural differences
Imaging Cells & Fibers Immunohistochemistry: We can localize molecular structures rather than just cellular structures. Can measure DNA & RNA activity
What is different? Process of IHC Fluorescent labeling Co-localization of molecules

Putting the theory to the test Can we find Collagen XVIII (18) in the brain? Using immunohistochemistry to locate structures.
Example: Cerebellum staining Collagen 18 found in Purkinje cells in the cerebellum!
Let's take a look: layers of fascia How images help us understand layers of tissue
