the sacromere
Muscles always contract entirely i.e. every part of the muscle which contains myosin and actin (contractile proteins) is able to contract and does contract almost simultaneously.
Muscle cells are formed in such a way that they contract and shorten. By doing this they produce a movement of one type or another. Skeletal muscle cells (called fibers) pull one bone towards another bone, smooth muscles fibers shorten as well but they don't act on bones. They produce waves of movement.
The organization of a skeletal muscle from smallest to largest is as follows: myofilaments > myofibrils > muscle fiber > fascicle > muscle
A living muscle needs oxygen in the blood and muscle elasticity to contract and move.
An atom is the smallest portion of an element that still retains its properties.
Smooth muscle cells contract in response to fluid flow.
pyriformis
it is tiny muscle fibers that contract and expand the muscle
No, as the muscle is dead (it doesn't contract like while the muscle is still alive either). However, it will contract if you give it an electrical "jump."
the smallest wavelengths and the highest energy are gamma rays.
I think its's the scalene muscle
