The non-contractile element are skeletal muscles that don't contract such as Epimysium,Perimysium and, Endomysium.
Contractile muscle contract as a whole muscle instead of single bundles of muscle fibers
The myocardium is the thickest layer of the heart made of contractile muscles that pumps blood.
Muscles
myofibrils
muscles
Contractile proteins is the term that identifies the proteins that allow muscles to shorten or lengthen.
Contractile proteins are found in what?
Yes the contractile proteins generate force during contraction and are actin and myosin
Myoblasts are a type of stem cells that exist in muscles.
yes
From what i understand it is scar tissue within the heart that will limit how well your heart can contract to pump out blood. Unlike your heart muscle tissue, the scar tissue will not contract.A heart attack would be the most likely cause for these scars.
There is no such thing. Were something non-contractile, it would cease to be called a muscle. You probably meant "What is a contractile muscle structure?" or something similar. There are many such answered questions on here.
Contractile impulse refers to the electrical signal that initiates contraction in muscle cells. In cardiac muscle, this impulse originates from the sinoatrial (SA) node, propagating through the heart to coordinate rhythmic contractions. In skeletal muscle, it results from signals transmitted by motor neurons. Overall, contractile impulses are crucial for the effective functioning of both cardiac and skeletal muscles.
