This is the name for the theory of how muscle contracts.
What is sliding filament theory?
100
EEG can pick up brain changes slower or faster than MRI?
What is faster?
100
In a concentric contraction, the muscle is doing this.
What is shortening?
100
In this disease, myelin on the axons in the central nervous system is gradually destroyed.
What is multiple sclerosis (MS)?
100
Muscles only perform this kind of action.
What is pull?
200
This is the fundamental contractile unit of muscle.
What is a sarcomere?
200
EEG can be compromised by what other electrophysiological signals?
What is EMG? (Heartbeat would also be acceptable).
200
If a muscle is contracting but staying the same length, it is performing this kind of contraction.
What is isometric?
200
This disease, with unknown underlying causes, is usually fatal within 3-5 years, with the prominent exception of one case where the patient has survived for decades.
What is ALS?
200
In sliding filament theory, myosin heads bind to this other type of protein.
What is actin?
300
Thick filaments are composed of this type of protein.
What is myosin?
300
ECog measures signals on the surface of the __________ (scalp or brain).
What is the brain?
300
If you are doing the first part of a squat, you are performing this kind of action.
What is eccentric?
300
This genetic disease is characterized by involuntary movements known as chorea.
What is Huntington's?
300
________ is used for energy in a muscular contraction.
What is ATP?
400
Thin filaments are composed of this type of protein.
What is actin?
400
Intramuscular and ____________ are the two types of EMG.
What is surface?
400
If a muscle is contracting eccentrically, it can produce more or less force that when it is acting concentrically.
What is more?
400
This disease of the neuron actually seems to be a result of a previous infection.
What is post-polio syndrome?
400
Ions of this element, also found in bones, are involved in the myosin head attaching to actin.
What is calcium?
500
This filament provides elasticity to the sarcomere.
What is titin?
500
This three letter acronym describes a mathematical technique that picks out neural sources from EEG data, like speakers could voices at a cocktail party.
What is independent component analysis or ICA?
500
Muscles can save energy by contracting this way and allowing tendons to stretch and release.
What is isometrically?
500
This communicable disease can be taken care of by doses of immunoglobin, taken immediately after the initial infection.
What is rabies?
500
When the body cannot provide ATP, do muscles stay ___________ (contracted or relaxed).
