Slow twitch fibers Slow-twitch fibers are muscle fibers that are used more when compared to the rest. Your legs are full of slow-twitch fiber because you are on your feet much of the time. Another name given for slow-twitch fiber is endurance fiber because they have been forced to adapt via being used so frequently and that is why it is harder for them to grow.
Fast Twitch Fibers Fast-twitch fibers are then obviously easier to grow because they are used less. When you are working out it is like they are being challenged for the first time. That is the reason why people see the most gains with these muscles when they first start working out.
Because hummingbirds are constantly on the move, they need stronger muscle fibres: their pectoral muscles are made up of almost 100% Type 1 muscle fibres which are better for the bird's endurance
muscle fibres
micro tears in muscle fibres
its form of fibres that are combined into parallel fibres. More specifically, it can refer to: * skeletal muscle * cardiac muscle
Yarn is made of fibres twisted together. These fibres or filaments are made of sheeps wool. :)
It prepares the muscle fibres for a tough workout.
organ is a structure made up of 2 or more no. of tissues(group of similar cells structurally and functionally)....artery is made up of endothelial cells, muscle fibres, elastic fibres etc placed in layers...hence is an organ. whereas capillaries only have endothelial cells.
Muscle fibres
Smooth: Lacks striations, thicker in middle and tapers at the ends, associated with involuntary muscle movements eg intestines.Skeletal: Striated, long fibres, that have multiple nuclei around the plasma membrane, typically attach to bones.Cardiac: Striated, branched muscle fibres that make up the heart, are shorter than skeletal muscle fibres.
The size of muscle fibres affect the tenderness of meat ; slender , small fibres are associated with tender meat ; large long fibres are associated with tougher meat.
The muscle layer of beef gullet meat tissue is made up of striated muscles and the tissue layer is composed of compact muscle bundles. The muscle fibres are tightly joined by endomysium. The protein content of the gullet meat tissue is similar to that found in less valuable sorts of meat.
eggshell is made up of calcite crystals and keratin fibres
