CT Cell #1 Fibroblasts
what are the 3 fiber types produces by fibroblasts?
1. collagenous (most important) 2. elastic 3. reticular
elastic fiber characteristics: (3)
1. fibers branch to form complex networks 2. very elastic, easily stretches 3. weaker than collagen
collagenous characteristics: (2)
1. long parallel groups of collagen 2.slightly elastic with great strength
elastic fibers are found in the: (3)
1. vocal chords 2. air passages 2. large blood vessels
fibers are found in almost every tissue, give 4 examples
1.dermis 2.muscles 3.ligaments 4.tendons
reticular is found in the CT of what organs? (2)
1.liver 2.spleen also lymph nodes
reticular fiber characteristics:
1.thin, small collagenous fibers 2.highly branched
collagenous fibers are composed of the protein
collagen
what is the major structural protein of the human body
collagen
elastic fibers are composed of a spring like protein called
elastin
fibroblasts produce 3 types of _____, by the secretion of _______
fibers; proteins
elastic fibers are hydrophobic/phillic
hydrophobic
we can compare fibers to very strong ____
ropes
collagenous fibers are found in:
the CT of almost every structure/organ
fibroblasts are the most common "fixed" cell. what does it mean to be "fixed"?
they do not move throughout the body once they are functional
reticular fibers form delicate supportive networks for cells of
tissues/organs
