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 else can I help you with?
What is the contraction for we were?
There is no contraction. The contraction we're means "we are."
What is the contraction for I was?
There is no contraction for I was. There is a contraction for I am (I'm) and for I have (I've).
What is the contraction for we'll?
There is no contraction of we'll. It is a contraction, meaning "we will."
What is the contraction for isn't?
There is no contraction. The word isn't is the contraction, meaning "is not."
What is contraction for pram?
There is no contraction for 'pram', it is a contraction of the word perambulator.
What is the short amount of time between the time of stimulation and the beginning of contraction in a skeletal muscle?
latent period
What are three period of myogram?
The three periods of a myogram, which records muscle contractions, are the latent period, contraction period, and relaxation period. The latent period is the brief time between stimulus application and the onset of muscle contraction. The contraction period follows, during which the muscle fibers actively shorten and generate tension. Finally, the relaxation period occurs as the muscle fibers return to their resting state, allowing the muscle to relax after contraction.
A period of macroeconomic expansion followed by a period of contraction?
A business cycle
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 is the period of isovolumetric contraction is immediately followed by?
The period of isovolumetric contraction is immediately followed by the period of ventricular ejection in the cardiac cycle. During isovolumetric contraction, the ventricles contract while all valves are closed, and this is followed by the opening of the semilunar valves to allow blood to be ejected from the heart during ventricular ejection.
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 period is characterized by calcium ions release into cytosol and depolarization of the sarcolemma and T tubules?
The period that would be characterized by those things would be muscle contraction. Calcium ions are the neurotransmitters that cause contraction. Calcium Ions depolarize the cell and are spread through out the muscle via the T tubules.
How long is the ventricular contraction period?
The ventricular contraction period, also known as systole, typically lasts about 0.3 seconds in a healthy adult heart. This is the phase when the ventricles contract to pump blood out of the heart.
