What is randomly coiled protein fibers that recoil after being stretch?
Elastic fibers made of the protein elastin has a coiled structure which allows it to stretch and recoil. Fibers can stretch up to 150 percent of their relaxed state length without breaking.
Which fibers in the skeletal muscle are stimulated only by the degree of stretch?
Type 2
What does the elastic fibers do?
Elastic solids stretch when pulled, get smaller when compressed/squeezed, and return to normal when no force is upon them.
What are norepinephrine releasing fibers called?
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
What controls sensation of heat?
Three types of sensory neurons are found in the skin. Aδ ("A-delta") fibers These are thinly-myelinated. They transmit signals in response to heat and touch. If the stimulus exceeds a certain threshold, the brain interprets these as acute pain. This is "good pain" because it warns you to do something to take care of the problems, e.g., a hot saucepan. C fibers These are unmyelinated and thus conduct impulses slowly. C fibers also respond to heat and touch. If the stimulus exceeds a certain threshold, the brain interprets these as diffuse, dull, chronic pain. This is "bad pain" because it cannot be alleviated simply by removing the stimulus. It is pain generated by such things as damaged tissue or pain that remains after the stimulus that caused acute pain has been removed. Aβ ("A-beta") fibers These are thickly-myelinated fibers. They mostly respond to painless stimuli such as light touch.

What fibers stretch across a cell during mitosisis?
spindle fibers
The Ca2 that is required for sustained contraction of smooth muscle fibers comes mainly from the?
extracellular fluid surrounding the fibers
Do muscles fibers stretch during contraction?
No, they contract.
What are the type of fibers that bend but firmly resist stretch?
Carbon fibers bend but firmly resist stretching.
Does stretch marks occur from breaks in the collagen fibers?
Yes.
WHY IS BOUNCING DURING A STRETCH IS NOT RECOMMENDED?
Bouncing can tear muscle fibers
Which fibers in the skeletal muscle are stimulated only by the degree of stretch?
Type 2
What are strong flexible fibers that hold the bones in place and stretch to allow bending?
ligaments
What does the elastic fibers do?
Elastic solids stretch when pulled, get smaller when compressed/squeezed, and return to normal when no force is upon them.
What is spandex made out of?
Spandex is made of a fiber called polyurethane. The fibers are woven together much like any clothing product. Spandex is used in socks, leotards and other clothes that stretch or have parts that stretch.
What is the function of elastic fibers in the trachea?
Longitudinal elastic fibers enable the trachea to stretch and descend with the roots of the lungs during inspiration.
