Muscle contraction is regulated by calcium ions, which will change thin filament into an activated state by binding to troponin. The binding of calcium to the troponin changes it's shape so the myosin binding sites on the actin (thin filament) are exposed
bind to regulatory sites on troponin to remove contraction inhibition

∙ 13y agoCa ion is the main thing in contaraction of muscles as ca ion adhere to the troponin in the muscle fibre actin n myosin filament join forming a cross bridge which results in pulling of actin filament and contraction occur......hope u satisfy by this ans can ask for detail at khushbukhan@hotmail.com

∙ 15y agomuscle contraction - Action Potential-Ca++ at terminal cisternae-troponin-removes the blocking action of tropomyosin Some basically it removes the blocking action of tropomyosin

∙ 9y agoIn the contraction of a skeletal muscle calcium acts to trigger the muscle for contraction. This occurs by removing the inhibition of troponin.

In addition to myosin what other protein is involved in skeletal muscle contraction?
Myosin acts with Actin during muscle contraction
What kind of connective tissue acts as a sponge from pulling away from bones during contraction?
Muscle
Neurotransmitter used to cause muscle contraction?
A neurotransmitter that causes muscle movement is called Acetylcholine. Acetycholine acts as on both the central nervous system and the peripheral nervous system.
An unpaired muscle that acts with the muscle to accomplish inspiration?
Inspiration is due to the contraction of the diaphragm and external intercostal muscles.
What acts as ATPase during the contraction cycle of muscle?
myosin cross-bridges
Is hadn't a pronoun?
Hadn't is a contraction of the verb 'had' and the adverb 'not'; the contraction acts as a verb.
What does hadn't mean?
Hadn't is a contraction of the verb 'had' and the adverb 'not'; the contraction acts as a verb.
Difference between agonist and antagonist?
Agonist works with the muscles, and the antagonist is the muscle working against it in a contraction. i.e. Bicep curl, the agonist is the Biceps brachii and the antagonist muscle is the triceps brachii.The word agonist means "producing an action" - an antagonist opposes that action. In medicine, an agonist binds to a receptor site and causes a response, often imitating the natural body reaction. An antagonist acts against this drug and blocks the response. for examples ramiels small balls and pubic hair
Is the word hadn't a verb or noun?
Hadn't is a contraction of the verb 'had' and the adverb 'not'; the contraction acts as a verb.
When a blood vessel gets damaged contractions of smooth muscle referred to as help constrict the vessels to reduce blood flow?
This is called myosin-regulated contraction. The entire muscle acts as a draw-string and constricts the vessel and slows blood flow.
Neurotransmitter that triggers muscle contraction?
Acetylcholine (ah-Seh-til-KO-leen) is the organic molecule that triggers muscle contractions in humans. Acetylcholine acts on both the central nervous system (CNS) and on the peripheral nervous system (PNS). It is also the principal neurotransmitter in autonomic ganglia.
How do muscles move?
Muscles move by contraction. When the cells shorten, the muscle pulls on the ligaments that connect the bones and the movable body parts. Depending on how a skeletal muscle acts, it may be classified as a flexor (decreases angle to joint) or an extensor (increases angle, straightening the joint).
