Chapter 1 Connective tissue Flashcards
What usually happens to the fascia that precedes deformity of osseus and cartilaginous structures in chronic disease?
It accomodates to chronic stress patterns and deforms itself (Wolff’s law)
What is a gentle requirement if a viscous drag and resistance are to be avoided when attempting to produce a change in, or release of, restricted fascial structures, and why?
A gentle touch.
Because resistance in colloids increases proportionally to the velocity of force applied to them (fascia = colloid)
What factors can cause excessive crossbridge bonding of the fascia?
Injury, chronic strses and immobility
After applying pressure to an area which has had it’s gel dehydrated contracted and hardened, the removal of the pressure allows the system to rapidly re-gel. The ground substance becomes more porous, a better medium for the diffusion of…..?
Nutrients, oxygen, waste products of metabolism and the enzymes and building blocks involved in the ‘metabolic regeneration process’
Rapidly applied force to collagen structures leads to..?
Defensive tightening
Slowly applied load gives what kind of response in the collagen structures?
Is accepted and allows for lengthening and distortion
Sometimes trigger points serve a function to correct underlying instability, which function
To give stability to an unstable situation
It is important to consider that, at times, apparent symptoms may represent…?
A desirable physiological response
It appears that the fascial tonus might be influenced and regulated by the state of which system?
Autonomic nervous system
How much of the bodys fluids is contained within the fascia?
1/4 of all bodily fluid
How many % of muscular decrease has been shown to occur after 3 weeks of immobilization?
47%
If immobilization continues beyond how many weeks before collagen loss is noted?
12 weeks
Loss of interfiber distance impedes the ability of collagen to glide smoothly, encouraging what?
Adhesion development
Because of immobility, new fiber connections will behave in what manner?
Laid down randomly, due to not having stress load to guide them in a directional format
Prolonged immobilization results in a number of alterations in tissue, including…?
Failure of collagen fibers to elongate and loss of collagen strength in as little as 4 weeks
