Soft tissue and MFR Flashcards
soft tissue includes
fascia, muscle, organs, nerves, vasculature, lymphatic
fascial anatomy
CT layers are composed of colalgen fibers (sometimes elastin) in an amorphous matrix of hydrated proteoglycans which mechanically links the collagen fiber networks in these structures
fascia is a
complete system with blood supply, fluid drainage and innervations
composed of irregularly arranged fribrous elements of varying density
fascia IS NOT
tendons
ligaments
aponeuroses
bone
pannicular fascia
outermost layer of fascia derived from somatic mesenchyme and surrounds entire body with exception of the orifices; outer layer is adipose tissue and inner layer is membranous and adherent, generally, to the outer portion
axial and appendicular fascia
internal to the pannicular layer; fused to the panniculus and surrounds all of the musscles, the periosteum of bone and peritendon of tendons
meningeal fascia
surrounds the nervous system; includes the dura
visceral fascia
surrounds the body cavities (pleural, pericardial and peritoneum)
fascia is omnipotent because
provides for mobility and stability of the MSK system
fascia is omniscient because
a bunch of receptors supply the fascia
viscoelastic material
any material that deforms according to rate of loading and deformity
stress-strain
stress is the force that attempts to deform a CT structure
strain is the percentage of deformation of CT
Hysteresis
energy loss due to difference between loading and unloading characteristics
creep
CT under a sustained, constant load will elongate or deform in response to the load
newtons third law
when two bodies interact, the force exerted by one is equal in magnitude and opposite in direction to the forces exerted by the other
