Stored ATP
Light Band is made of
Actin
T or F, Muscles can produce less force by partially contracting fibers
F
The cell membrane of a muscle
Sarcolemma
Supports the movement of an agonist
Synergist
Replenishes ATP when depleted
Creatine Phosphate
Fast Oxidative muscles
Type II a
Myofilament with "heads"
Myosin
Connective tissue that holds muscles together
Fascia
Neurotransmitter for voluntary muscles
Acetylcholine
Supplies some energy most of the time
Aerobic Respiration
Another name for Slow Oxidative fibers
Type I
Place that a muscle pulls toward
Origin
Name of space between nerve ending and muscle surface
Synapse
Contraction type that causes no movement
Isometric
An energy pathway that causes the buildup of lactic acid
Glycolysis
Most prominent muscle type in an olympic sprinter
Type IIb
Can be caused by a depleted supply of ACh or a lack of oxygen in the muscle.
Muscle fatigue
More strength is produced by stimulating more of these.
Motor units
Neurotransmitter for smooth muscle tissue
Norepinephrine
Post Mortem condition caused by lack of ATP in muscles
Rigor Mortis
Type II ab
_____ Is caused by calcium being transported back into the SR, and the breaking of cross bridges.
