Muscle Fiber types
Another name for slow twitch fibers
What are Type I muscle fibers
The sequence of steps beginning with information from the nervous system and ending with calcium returning to the SR is referred to as:
What is a twitch
blood returning from the body first enters this chamber of the heart:
What is the right atria
A decrease in the size of a muscle due to injury or inactivity
What is atrophy
These fibers contain high levels of mitochondria and capillaries
What are type I musle fibers
When a twitch is repeated several times and a muscle contraction occurs, this is also called
What is treppe or the sliding filament theory
Blood moves through this valve to move from the right atria to the right ventricle
What is the AV valve
Tearing of the z-lines from strength training will lead to this process, which increases the crosse sectional area of a muscle fiber
What is hypertrophy
These fibers contain large amounts of myosin ATPase and very few mitochondria
What are Type IIb muscle fibers
Another name for a muscle contraction
What is tetanus
Blood moves from the right ventricle to this structure to re-oxygenage blood
What are the lungs
The motor neuron and the fibers that it connects to is called this
What is a motor unit
These fibers are white in color and fatigue quickly
What are type IIb muscle fibers
this is the connection between the muscle and the nerve
What is the neuromuscular junction
Blood moving from the lungs to the heart will first enter into this chamber
What is the left atria
This type of action occurs when there is a motor unit ration that is 1:few
What is fine motor control
These fibers contain mitochondria, myosin ATPase, and are pink in color
What are Type IIa muscle fibers
What happens when the last step of a twitch does not occur and calcium does not return to the SR
What is complete tetanus
Blood leaving the left ventricle will move through the semi-lunar valve and into this structure
What is the aorta
Using the elastic abilities of titin will result in this process
What is the length tension relationship
