1
Red muscle fibers that contain a high myoglobin and blood vessel count. They generate ATP by aerobic cellular respiration, and anaerobic glycolysis due to their high intracellular glycogen levels.
2
White muscle fibers with a low myoglobin content. This type of muscle fiber contains large amounts of glycogen and as such mainly generates ATP by glycolysis.
3
Refers to development of a constant tension, with no change in the length of the muscle. This type of contraction does not create movement, and is used for bearing loads.
4
Refers to the development of a constant tension, during a change in the length of the muscle.
5
Red muscle fibers commonly found in the muscles of the back. They contain large amounts of myoglobin and many large mitochondria and use aerobic cellular respiration to generate ATP.
6
The period of crossbridge formation.
7
A fast, brief contraction of a muscle following a single stimulus. This stimulus is usually brief and can be either strong or weak, depending on the number of motor units recruited.
8
Occurs once peak tension has been developed and stimulation is removed
9
The period of time between the stimulation of a muscle fiber and contraction of that muscle.
10
Consists of a somatic motor neuron and all of the muscle fibers it innervates.
