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
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.
muscle fibres
The muscle fibres are contracting
Muscle fibres
Muscle fibres are connected to neurones on either a 1:1 ratio (such as fingers, where precise muscle control is needed) whereas some muscle fibres are connected to neurones in a 1 neurone:several muscle fibres ratio. The second occurs where precise movement is not needed, such as the calf muscle, where a stimulus needs to cause a large and synchronised contraction of muscles as opposed to precise contraction of certain individual fibres.
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
Upper fibres-from maxilla opposite molar teeth. lower fibres-from mandible opposite molar teeth middle fibres-from pterygomandibular raphe.
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.
It prepares the muscle fibres for a tough workout.
