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
