How does the PNS affect the organs of the body?
With regard to specific target organs and tissues, parasympathetic stimulation acts to decrease heart rate and decrease the force of contraction. Parasympathetic stimulation also reduces the conduction velocity of cardiac muscle fibers.
What is the function role of t tubules?
Enhance cellular communication passage for nervous stimulation during muscle contraction.
Is Cardiac muscle stimulation neural?
No, but skeletal muscle is.
What conclusions can you draw about the relationship between a muscle's workload and its threshold of stimulation?
As the muscle workload increase, its threshold of stimulation increases.
Why do you get muscle spasms?
Muscle spasm are caused by due to hyper or hypo stimulation of the peripheral nerves which in turn decrease or increase the action.
After nervous stimulation of the muscle cell has ceased the calcium in the muscle?
uhhh
What muscle can contract without the need for the nervous stimulation?
Smooth & cardiac muscle.
What is the substance that halts stimulation of muscle tissue?
Acetylcholine
How did the frequency of stimulation affect the amount of force generated by the isolated skeletal muscle when the frequency of stimulation was increased such that the muscle twitches did not fully re?
Decreased force production
What types of muscle tissue can depolarize spontaneously in the absence of any external stimulation?
cardiac muscle and smooth muscle?
The very brief moment following stimulation when a muscle remains unresponsive to additional stimulation is called the?
refractory period
The first step toward generating a skeletal muscle contraction?
stimulation of the muscle by a nerve ending.
