Period of Contraction is the second stage of a muscle twitch, when cross bridges are active, from the onset to the peak of tension development, and the myogram tracing rises to a peak. This period lasts 10-100 ms. If the tension (pull) becomes great enough to overcome the resistance of a load, the muscle shortens

What is the short amount of time between the time of stimulation and the beginning of contraction in a skeletal muscle?
latent period
A period of macroeconomic expansion followed by a period of contraction?
A business cycle
What is the ventricular contraction period?
This is called the systole :)
How long is the ventricular contraction period?
0.3 Seconds
Period of heart contraction?
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.
What is the start of the contraction phase in a business cycle called?
Similarly, a period of recession occurs at the start of the contraction phase.
What us a period of macroeconomic expansion followed by a period of contraction?
business cycle-- good luck
What does systole refer to?
The period of time marked by contraction of the ventricles
The neuron cannot respond to a second stimulus no matter how strong?
Absolute refractory period
The period during which the ventricles are depolarizing which precedes their contraction?
QRS wave
What chemical reactions occur in the muscle during latent period of muscle contraction?
During the latent period of muscle contraction Ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack. This takes approx. 2 milliseconds.
What does the term systole mean?
Systole is the period of heart contraction within the cardiac cycle.
