Fascia Flashcards
What is the predominant cell type in fascia
Fibroblasts
Where is the collagen in fascia produced.
Fibroblasts
When are fibroblasts active? what do they do?
Build and repair extracellular matrix, removes waste, brings in nutritive factors, aligns the collagen
active when they are stretched
How can we affect the alignment of the collagen fibers?
Align with mechanical stress that is applied
How do our everyday activities affect fascia
Fascia that is used everyday becomes stronger, if tension our fascia in only one direction, it will get stronger in that direction at the expense of other movements
How does exercise affect the synthesis and breakdown of collagen.
Initial training period ther is a net loss of collagen in tendons. Allow tendons to adapt to new stress. As training continues will acquired net gain in collagen
What role do adipocytes play in fascia
Provide protection form the forces of everyday life. Protect tissues from shear forces, pressure and allow tissues to slide smoothly
What happens to the alignment of collagen in fascia when we don’t exercise
Without stress, fibroblasts become inactive and collagen fibers become chaotic
What is the biggest sensory organ in the body
Fascia
How does high sympathetic tone affect fascia
Sympathetic innervation is found near the myofibroblasts in fascia. High sympathetic tone leads to fascial stiffness
Describe how fascia plays a role in separating tissues of the body
Separates the tissues to allow movement
Describe how fascia play a role in sharing via mechanical stress and the nervous system
Mechanical stress in on region can be transmitted over a distance and is a rapid form of information, neurologic signals are slower and are independent of context. Mechanical force distribution is faster and is context dependent.
What happens to muscle force if we split the surrounding fascia
Produced 15% less forces
Where is the superficial fascia
Just below the skin, more sensory function, deep is more proprioceptive in function
What benefit is there when the epimysial fascia is connected to an aponeurosis
Aid in the transmission of force from the trunk to the limbs and vice versa
