Muscle cells can contract and relax and lave fibers as long as 1.5 feet.
Muscle cells have fibers that can contract and relax. These fibers, known as myofibrils, contain the proteins actin and myosin that allow them to slide past each other and generate force. This contraction and relaxation of muscle fibers enable movement in the body.
The name of the long cells that can stretch and contract in the body are called muscle fibers. These fibers make up our muscles and are responsible for movement and generating force in the body.
Muscle cells are called fibers.
They are called Fibers
Muscle cells are often referred to as muscle fibers because of their long and slender shape, resembling fibers or strands. This elongated shape allows muscle cells to contract and generate force efficiently, which is essential for movement and muscle function.
The cardiac muscle fiber absolute refractory is a long period of time (longer then skeletal muscles), so you cannot tetanize cardiac muscle fibers because it has to relax before it is able to contract again.
Long, tough, tapered plant cells are called fibers:) enjoy
The long and fibrous structure aids in contraction of the muscle cells. It's like Velcro when touch each other they inevitably contract and they keep touching which makes them contract more untill they relax
muscle cells
Muscles contract and relax all the time. Without more information it is impossible to help you. What reason do you need to relax it or them in the first place. What kind of muscle are you talking about.
muscle fibers
There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.
