What is the process of excitation contraction coupling?
cross bridge formation "Excitation-contraction coupling" connects muscle fiber excitation to the muscle fiber contraction (cross bridge formation). During contraction, myosin heads form cross bridges many times-with each cross bridge generating a small amount of tension in the muscle fiber.

What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
Myofibrils
What do you call a shortening of muscle fiber?
contraction
What is shortening of a muscle fiber called?
a contraction human avatommy
What does contraction mean in medical terms?
contract or "contraction" is when a muscle fiber lengthens or shortens
What are all muscle cells called?
A single muscle cell is called a muscle fiber.
What happens when thin filaments in a muscles fiber slide over the thick filament?
Contraction or relaxation of muscle fibre, due to similar effect in sarcomere
What allows recoil of the muscle fiber when contraction ends?
Elastic filaments
The energy source that is directly responsible for muscle fiber contraction is?
ATP
What is the function of cytoplasmic reticulum in the muscle fiber?
increases calcium influx in the muscle fibre, causing contraction.
