what are the major differences between the various muscle fibre types?
15797
The two types of skeletal muscle fibers are slow-twitch (type I) and fast-twitch (type II). Slow-twitch muscle fibers support long distance endurance activities like marathon running, while fast-twitch muscle fibers support quick, powerful movements such as sprinting or weightlifting.

There are two main types of twitch muscles: Fast twitch muscles. These muscles help with sudden bursts of energy involved in activities like sprinting and jumping. Slow twitch muscles. These muscles help with endurance and long-term activities like running or bicycling.

There are three different types of myofilaments: thick, thin, and elastic filaments. Thick filaments consist primarily of the protein myosin. Each thick filament is approximately 15 nm in diameter, and each is made of several hundred molecules of myosin. ... All thin filaments are attached to the Z-line.

There are three types of myofilaments: Thick filaments, composed of protein molecules called myosin. In striations of muscle bands, these are the dark filaments that make up the A band. Thin filaments are composed of protein molecules called actin.

A myocyte (also known as a muscle cell) is the type of cell found in some types of muscle tissue. Myocytes develop from myoblasts to form muscles in a process known as myogenesis. ... On the other hand, skeletal muscles are formed by morphological units referred to as muscle fibers.

Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other.

Skeletal muscle has four major functional characteristics: contractility, excitability, extensibility, and elasticity.

Muscle fibers can contract because they are made of proteins, called actin and myosin, that form long filaments (or fibers). When muscles contract, these protein filaments slide or glide past one another, shortening the length of the cell. When your muscles relax, the length extends back to the previous position.

Myofilaments are the filaments of myofibrils, constructed from proteins, principally myosin or actin. Types of muscle are striated muscle (such as skeletal muscle and cardiac muscle), obliquely striated muscle (found in some invertebrates), and smooth muscle.

The major skeletal muscle groups forming the upper body are the abdominal, pectoral, deltoid, trapezius, latissimus dorsi, erector spinae, biceps, and triceps. The major skeletal muscle groups of the lower body are the quadriceps, hamstrings, gastrocnemius, soleus, and gluteus.

A muscle cell is called a sarcomere. a myofibril are several sarcomeres connected to each other as a long strand. several of these myofibrils bunched together form a muscle fiber. ... YES, a muscle cell is a muscle fibre, they mean the same thing, but a muscle fibre really is not a muscle cell.

Muscle tissues differ in structure. Skeletal muscle fibres are packed into regular parallel bundles. Smooth muscle has bundles of thin and thick filaments. Cardiac muscle bundles are branched but connected.
1446544
Muscle Types: Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.

Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle.
