Does calcium has any role in vasoconstriction?

Yes it does, as a matter of fact calcium plays a huge role in muscle contraction, as so in the smooth vascular muscle.


What is the role of calcium ions in muscle contraction?

They bind to regulatory sites on troponin to remove contraction inhibition


What is the role of the triad in muscle contraction?

Once a triad has been achieved, Calcium ions get released. Once they're released they bind to troponin, which helps begin muscle contraction.


What helps muscles contract?

Calcium plays an important role in muscle contraction. Calcium is one of the most common minerals found in the human body.


What is the role of myosin APT ase in muscle contraction?

Myosin ATPase hydrolyze ATP into ADP+pi and yielding the energy required for muscle contraction.


What is the role of ATP in maintaining calcium concentration gradients?

Calcium must be actively pumped back into the terminal cisterns of the sarcoplasmic reticulum to terminate the contraction and relax the skeletal muscle. For every Ca2+ transported, one ATP molecule is hydrolyzed.


What is the function role of t tubules?

Enhance cellular communication passage for nervous stimulation during muscle contraction.


Is calcium a fiber?

No. Calcium does have a major role in muscle fibers when your muscles contract, but it is not the actual fiber.


What role does the nervous system play in muscle contraction?

controls the muscles by the motor nurons.


Enlarged portion of sarcoplasmic reticulum on either side of a transverse tubule?

The enlarged portion of sarcoplasmic reticulum on either side of a transverse tubule is called a terminal cisterna. These terminal cisternae play a vital role in the excitation-contraction coupling of skeletal muscle cells. They store and release calcium ions, which are essential for muscle contraction.


Which electrolyte has a major role in muscle contraction and high or low levels of it can leacd to cardiac arrest?

potassium


What is the role of atp in muscle concentration?

Atp plays a critical role in muscle. Breaking of the cross-bridge is possible only if atp binds to myosin, thereby allowing it to be free for the following contraction.
