Question
Chapter 5.8, Problem 24CYU
Summary Introduction
To review:
The type of muscle tissuethatacts an effector to regulate constriction and dilation of blood vessels.
Introduction:
The temperature of blood in the body is an integral part of homeostasis that helps to regulate the normal functioning of the body. In order to achieve the maximum output of work from the body, it is important for the internal temperature to remain within the homeostatic limits. The temperature of the blood is a result of the temperature prevailing in its surroundings.

What can muscle tissue do that nervous tissues can’t.
Muscle Physiology
Some skeletal muscle fibers are “fast-twitch” fibers (white fibers), and others are “slow-twitch” (red) fibers. Would you expect an athlete proficient in running the 100-yard dash to have a greater proportion of red fibers or white fibers in muscles of the leg? Why?
Define the following:
Maximal stimulus
Threshold stimulus
Submaximal stimulus
A skeletal muscle can be stimulated, under laboratory conditions, with a supramaximal stimulus. Is it possible for the muscle to respond with a supramaximal contraction? Explain
Define a motor unit. Of what physiological advantage is a small motor unit arrangement in skeletal muscle?
Explain why a latent period is observed between the application of a stimulus and contraction of the stimulated muscle.
Explain, giving two causative factors, why skeletal muscle displays fatigue.
Does complete or incomplete tetanus occur physiologically? Explain.
Define the following:
Isometric contraction
Isotonic contraction
Optimum length…
Why smooth muscles appears to have the largest nuclei? Isn't it skeletal muscle?
