FASCIA quiz Flashcards
what is fascia
masses of soft tissue component in CT
3D matrix of collagen fibers interwoven that support and surround every structure in the body
what is connective tissue
tissue that connects or separates and supports other types of tissues in the body
MOST abundant body tissue
what is the composition of CT?
extracellular matrix
cells
what is the extracellular matrix
made of protein fibers and ground substance
found between cells and fibres
what is ground substance
fluid part of connective tissue
water is main component
thixotropic -gel when moved but turns thick if not moved
resists abrupt pressure but yields to slow sustained pressure
most abundant protein in body
collagen
what are produced by fibroblasts
reticular fibres
where are collagen fibers found
CT, bone, cartilage, tendons, ligaments
where is elastic fibers found
skin, blood vessel walls, lung tissue
where are reticular fibers found
reticular CT that form a stroma
what are the 3 types of fibers embedded in the ECM
collagen
elastic
reticular
what are the specialized cells in fasica
fibroblasts
myofibroblasts
collagen
smooth muscle cells
telocytes
myofibroblasts contain actin and myosin T/F
true
what are telocytes
specialized mechanosensitive CT cells that have roles in homeostasis
what is tensegrity
refers to structures that maintain their integrity due to a balance of woven tensile forces
structural shape that is guaranteed
hooke’s law
stress imposed on tissues is directly proportional to the strain produced within the elastic limits of the tissues
wollfs law
tissues remodel in response to forces placed upon them
what are the 4 properties of fascia
colloid, thixotropic, elastic, plastic
define colloid in regards to fascia
particles suspended in fluid resist abrupt pressure but yield to slow sustained pressure
define thixotropic
substance liquefies on agitation and reverts to gel when standing
functions of fascia (6)
protects, surrounds, separates tissues
connects structures, providing stability, absorbs forces
allows tissues to glide and slide on each other
has sensory functions
highly innervated, participates in proprioception, interception, senses pain
has colloidal viscoelastic, elastic and plastic properties
what are the 4 classifications of fascia
linking
fascicular
compression
separating
what are the 4 loactions of fascia
superficial
deep
meningeal
visceral
where are the transverse fascial planes located
cranial base
cervical thoracic area
diaphragm
lumbar and pelvic floor areas
3 types of fascial ax
skin rolling
fascial glide
positional testing
