PHYSIOLOGY OF SKELETAL MUSCLE

1. Skeletal muscle
Part 2

4. Muscle fibers have three ways to produce ATP:
(1) from creatine phosphate
(2) by anaerobic glycolysis
(3) by aerobic respiration
Production of ATP in Muscle Fibers

10. A twitch contraction is the brief contraction of all
muscle fibers in a motor unit in response to a single
action potential in its motor neuron.
The record of a muscle contraction, called a myogram
