muscle tissue
It is Contractile Vacoule. Contractile Vacoule, a structure that collects the extra water and then expels it from the cell.
A specific type of vacuole, called a contractile vacuole expels excess water from many fresh water protists.
No they do not have contractile vacuoles.
Muscles
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.
Dead myocardial tissue gets replaces by collagenous fibrous tissue, which is non-contractile.
Contractile tissue.
muscle tissue
muscle
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
if the lesion is in a contractile tissue i.e muscle then active n passive movements are painful and/or restricted in opposite direction of motion.
a cell
skeletal muscle is made up of permanent cells - ie they never divide. this means if it is lost then it will heal by repair with organisation and progressive fibrosis = scar formation.
Muscle (from Latin musculus, diminutive of mus "mouse"[1]) is a contractile tissue
myocardium
it depends on what type of damage. when the heart heals, instead of forming normal heart tissue, it forms non-contractile scar tissue. if you are asking if the heart can get stronger after its been damaged, the answer is yes. the heart has many compensatory mechinisms.
