As you've got figured out, just about every skeletal muscle fiber must be innervated via the axon terminal of a motor neuron as a way to contract. Each and every muscle mass fiber is innervated by just one motor neuron.
for the duration of tetanus, the concentration of Ca++ ions from the sarcoplasm enables pretty much all of the sarcomeres to sort cross-bridges and shorten, to ensure that a contraction can keep on uninterrupted (until finally the muscle fatigues and can now not deliver tension).
on the other hand, we however will not have an precise method for figuring out the amounts of ATP and phosphocreatine close to the sarcoplasmic reticulum in the intact, in vivo
Skeletal muscles are rarely totally calm, or flaccid. even though a muscle mass isn't manufacturing motion, it can be contracted a little amount to take care of its contractile proteins and create muscle mass tone.
Other mechanisms proposed in variations to the tension-frequency relations may be due to lowered amount of SERCA pumps, lowered cAMP manufacturing, intracellular acidosis, or metabolic buildup secondary for the greater diffusion distances in hypertrophied myocytes.[4]

throughout incomplete tetanus, the muscle mass goes as a result of swift cycles of contraction with a short relaxation phase for each. If your stimulus frequency is so higher that the leisure section disappears entirely, contractions become steady in a process termed finish tetanus (determine 4b).
The Bowditch influence is often called the Treppe phenomenon, staircase phenomenon, or frequency-dependent activation. It refers to the concept that an boost in coronary heart level enhances the power of contraction produced by the myocardial cells with Each and every heartbeat Inspite of accounting for all other influences. This concept of innentreppen the frequency-based mostly positive inotropic reaction of the center was very first explained in 1871 by the physiologist Henry Pickering Bowditch following he stimulated a resting frog’s ventricular apex.
