Natural materials are by definition biodegradable. That means that cotton, wool, linen and silk fulfill this criterion. Cotton and linen are cellulose based (a polysaccharide) while wool and silk are made of protein types )wool is made of keratin as is human hair). Of the others only certain types of polyesters are biodegradable such as for example polylactic acid. What is commonly labeled as polyester in garments is not biodegradable.
Just a guess but the fibers in clothing. ( cotton fibers, polyester fibers, etc)
The fibers which are made by man are the synthetic fibers.
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
Synthetic Fibers Manufactured Fibers
Sharpey's fibers
Collagenous fibers, Elastic fibers, and Reticular fibers
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
the three basic types of fibers that are found in connective tissue are collagen fibers, elastic fibers, and reticular fibers
No, parasympathetic postganglionic fibers do not come from adrenergic fibers. Parasympathetic postganglionic fibers release acetylcholine as their neurotransmitter, whereas adrenergic fibers release norepinephrine.
