slow

speed of contraction of fast oxidative fibers

medium

speed of contraction of fast glycolytic fibers

fast

method of ATP production in slow oxidative fibers

method of ATP production in fast oxidative fibers

mostly aerobic respiration and some anaerobic glycolysis

method of ATP production in fast glycolytic fibers

mostly anaerobic glycolysis

quantity of mitochondria/capillaries/myoglobin in slow oxidative fibers

many

quantity of mitochondria/capillaries/myoglobin in fast oxidative fibers

moderate

quantity of mitochondria/capillaries/myoglobin in fast glycolytic fibers

few

fatigue resistance in slow oxidative fibers

slow to fatigue

fatigue resistance in fast oxidative fibers

fatigues quickly

color of slow oxidative fibers

red

color of fast oxidative fibers

pink

color of fast glycolytic fibers

white

use of slow oxidative fibers

long duration

use of fast oxidative fibers

medium duration

use of fast glycolytic fibers

short duration, intense movement

control of skeletal muscle

voluntary control

location of skeletal muscle

attached to bones

nucleus quantity of skeletal muscle

multi-nucleated

skeletal muscle striations

organized into sarcomeres and are striated

control of smooth muscle

involuntarily controlled

location of smooth muscle

found in sheaths around most organs, in blood vessels and in glands

nucleus quantity of smooth muscle

one nucleus per cell

smooth muscle striations

are not organized into sarcomeres so they are not striated

control of cardiac muscle

involuntarily controlled

location of cardiac muscle

in the heart

nucleus quantity of cardiac muscle

sometimes have one nucleus, sometimes are multinucleated

cardiac muscle striations

has less organized sarcomeres but is still striated
