Muscles provide movement, especially the skeletal muscles. The smooth muscles in our organs produce movement called peristalsis or tonic contraction which holds sphincters closed.
Skeletal muscles are attached to the bones by tough cords called tendons. When nerve signals are sent from the brain and spinal cord, these muscles contract to produce movement.
Your skeleton does not actually produce movement. That is the job of your muscles. When they contract they pull on bones which are joined together by joints. The joints function much the same as a fulcrum and produce three different types of levers depending on where the muscles attach. The most stable attachment is called the origin, and the more movable one is called the insertion. It is the bone that has the insertion end of the muscle that we are familiar with as the bone that moves.
This process is called contraction. Muscles shorten or contract to produce movement.
Of all the muscles contracting simulataneously, the one that is mainly responsible for producing a particular movement is called the prime mover for that movement. The other muscles that help in producing the movement are called synergists. As prime movers and synergists muscles at a joint contract, other muscles, called antagonist muscles, relax.When antagonist muscles contract, they produce a movement opposite to that of the prime movers and their synergist muscles. -- I wrote kind of alot so you can under stand it just in case if you don't :)
Tissue made of cells that contract and relax to produce movement is called muscle tissue.
Atrophy
One is the agonist and the other is called the antagonist. Agonist: muscle which is the main mover, it contracts and shortens Antagonist: muscle that lengthens and controls e.g. flexion at the elbow: the biceps are the agonist and the triceps are the antagonist.
The ligament and the cartilage combine together to make movement. One makes the movements and the other doesn't. And joints makes movements and also it called indolence.
because its attach to the bones movement is a shorten shorten contrast
they are called caultonary muscles. YOU want to use them
The muscle that is responsible for most of a movement is called a prime mover. It may also be called an agonist.
