- To understand the relationship between the structure of a sarcomere and its function.
- To clarify the principle stages of muscle contraction.
- To bring out the relationship between the shrinking of I bands and the sliding of myofilaments.
Locomotion is the result of the contraction of skeletal muscles.
The observation of a muscle fiber under an transmission electron microscope (TEM) reveals alternating light and dark bands. The…
