What main Ion plays an important role in the SFT?
what are Calcium Ions
What is the smallest functional unit of a muscle fiber?
Sarcomere
What are the two myofibrils(filaments) that are associated with this theory?
What is Actin and Myosin
What are the three main connective tissues in the Muscle?
What are Endomysium, Perimysium, and Epimysium
_____is the long chains of repeating sarcomeres stacked end-to-end inside each muscle fiber?
What is Myofibrils?
What protein does Calcium bind to on the actin filament?
What is Troponin?
What is the role of the dendrites?
What is to receive information via receptors?
When the myosin head binds to the actin what is being used to energize the "power stroke"?
What is ATP
Which fiber has these characteristics: slow contractile speed, ideal for aerobic activities?
What is Slow Twitch?
What is the condition when myosin head does not detach from the actin filament (troponin)
What is Rigor Mortis
Which part of the muscle does the voltage signal travel down on?
What is the T-Tubules?
What is the name of the cell that wraps around an axon to increase AP velocity? Prior Knowledge (DJ)
What is Schwan Cell
Describe the sequence of Power Stroke in the S.F.T? (TJ)
What is the myosin head rotates, pulling the actin filament inward. The conformational change drives actin movement...accompanied by the release of ADP+P
Which muscle fiber type is the last to be recruited?
What is Fast Twitch B
This term is refered to as the whole muscle
What is Muscle Belly
Hyperplasia is? Not in Notes (DJ)
The increase in the number of muscle fibers.
What is the role of the sarcoplasmic reticulum?
to store and release Calcium Ions?
Name the enzyme associated with returning Ca back to the Sarcoplasmic reticulum?
What is SERCA(Ca ATPase)
What amino acid do you think plays a big role in pulling water into our cells? (TJ)
What is Creatine
What happens once calcium binds to the actin filament?
This is a Genetic Disorder that causes progressive muscle weaking and loss of muscle mass due to defective proteins
What is Muscular Dystrophy?
What mechanism must occur in order for calcium to be released into the muscle cell sarcoplasm? (TJ)
What is The RyR receptor must open in order for calcium to be released. it needs an electrical signal propelling from the tubules?
If I am a swimmer and compete in the 50 meter race, but I do this several times in one hour, what type of muscle fibers would be optimal for my success? (DJ)
What is FTa
______ are the functional units in myofibrils?
What are Sacromeres?
