Muscle 5 Flashcards
What is fused tetanus?
Maximal amount of force that can be generated in a single muscle fibre
What is the size principle
As the stimulus onto the motor neuron pool increases, additional larger motor neurons are recruited
What is the size of each motor unit recruited
It is bigger then the motor unit before
Small motor neurons innervate what muscle fibre type
Type 1
What is isotonic contraction
When the muscle contracts, shortens, and creates enough force to move the load
What is isometric contraction
The muscle contracts but does not shorten
What is concentric contraction
Muscle shortening while generating force
What is eccentric contraction?
Muscle lengthens while generating force
What fuses existing muscle fibre to cause regeneration after an injury?
Satellite cells
What is muscle hypertrophy
The increase in muscle mass that results from the growth of muscle fibres
What type of fibre show greater rate of myofibre hypertrophy?
Type II
