False.
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.

Type 2 muscle fibre.
Type 2
Skeletal muscle fibers can get ATP from 3 sources: -Phosphagen system (a few seconds) -Anaerobic fermentation (less than 2 minutes) -Aerobic respiration (indefinite)
1. Provide a route for entry and exit of nerves and blood vessels that serve the muscle fibers. 2. Provide strength to muscle as a whole3. Support and bind muscle fibers
Type IIa Red fibers. Fast oxidative (also called fast twitch A or fatigue resistant fibers). Contain:Large amounts of myoglobin.Many mitochondria.Many blood capillaries.High capacity for generating ATP by oxidation. Split ATP at a very rapid rate and, hence, high *contraction velocityResistant to fatigue but not as much as slow oxidative fibers.Needed for sports such as middle distance running and swimming.Type IIb White. Fast glycolytic (also called fast twitch B or fatigable fibers). Contain:Low myoglobin content.Few mitochondria.Few blood capillaries.Large amount of glycogen.Split ATP very quickly.Fatigue easily.Needed for sports like sprinting.Hope it is useful to you!
Muscle contraction is affected by four factors:1. The number of muscle fibers stimulated 2. The relative size of the fibers 3. Frequency of stimulation 4. The degree of muscle strength
Type 1 (slow twitch oxidative) , type 2a (fast twitch oxidative) and type 2b (fast twitch glycolytic).
Action of the muscle Shape of the muscle Location of the muscle's origin and or insertion Number of origins Location of muscle relative to a bone or body region Direction in which the muscle fibers run relative to some imaginary line Relative size of the muscle
The type of muscle tissue that have only one or two nuclei per cell are cardiac muscle cells. Their nuclei are located in the center of a cell.
