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.
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth 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.
No. Cardiac muscle fibers.
The three type of muscle fibers are fast-twitch, slow-twitch, and hybrid.
Smooth Muscle Fiber
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.
No, intrafusal fibers don't contract.
Slow oxidative fibers Fast oxidative-glycolytic fibers Fast glycolytic fibers
Both fast oxidative and fast glycolytic muscle fibers are types of fast-twitch muscle fibers that contract quickly and generate a lot of force.
Epimysium: the outermost layer that surrounds the entire muscle. Perimysium: surrounds bundles of muscle fibers called fascicles. Endomysium: encases individual muscle fibers within a fascicle.
