There are different types of muscle fibers. There is skeletal muscle, cardiac muscle and smooth muscle. * Skeletal muscle is attached to bones or occasionally skin. * Cardiac muscle is found in the walls of the heart. * Smooth muscle is mostly found in the walls of hollow organs such as the intestines I am currently studying anatomy and physiology at University for my nursing degree.
There are three muscle Types: Skeletal, Smooth and Cardiac.

All muscle cells are elongated and are called muscle fibers. Muscle contraction depends on two kinds of myofilaments (actin and myosin). The cell membrane of a muscle cell is called "sarcolemma", while the cytoplasm of a muscle cell is called "sarcoplasm".

Skeletal muscle characteristics: long, thin and multi-nucleated fiber with striations, voluntary control; arranged into packages called muscles that attach to and cover the bony skeleton; contracts rapidly & vigorously, but tired easily; may exert great force.

Cardiac muscle characteristics: network of branched fibers connected by gap junctions (intercalated disks); only in heart; also have striations; involuntary control; contracts at rhythmic, steady rate set by "pacemaker".

Smooth muscle characteristics: lacks striations; walls of hollow visceral organs and blood vessels; involuntary control, contractions are slow & sustained.

cardiomyocyte (in heart), skeletal muscle myocyte (it is more like syncitium, not a single cell) and smooth muscle myocytes (those of digestive tract for example)

What is the role of slow muscle fibers and fast muscle fibers in the response of a muscle to different types of exercise?

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.


Smooth muscle fibers are the shortest of all muscle cell types?

No. Cardiac muscle fibers.


What are the three types of muscle fibers?

The three type of muscle fibers are fast-twitch, slow-twitch, and hybrid.


Muscle sphincters are composed of what two types of muscle fibers?

Smooth Muscle Fiber


Do all types of muscle fibers produce movement?

No, intrafusal fibers don't contract.


Do different muscles react at different speeds?

There are two types of muscle fibers, fast-twitch and slow-twitch. Each muscle is a combination of different proportions of these fibers. Muscles in different people have different compositions, which is why some athletes are better marathon runners, while others are better sprinters.

What are slow twitch muscle fibers?

Our bodies are made up of different types of muscle fibers, all of which rely on different energy systems. Slow twitch fibers, as the name suggests, contract more slowly than fast twitch muscle fibers and they can contract for a longer period of time. We often call these 'endurance' muscles because they're great for aerobic activities that require endurance like running, cycling and swimming. In general, many of us will have about 50% slow twitch fibers and 50% fast twitch fibers, although it will differ between individuals. Successful long-distance runners will often have more slow twitch fibers while sprinters or bodybuilders will often have more fast twitch fibers. Strength training in different rep ranges (from 4-16) will allow you to work different muscle fibers and energy systems in your body.
