Lab Final Flashcards
effect of increasing stimulus voltage on isolated skeletal muscle
increased stimulus=increased active force produced by the muscle
treppe
when muscle comes to rest before contracting again but each contraction is stronger than the next
wave summation
rapid stimulation without full rest in between
unfused tension
incomplete tetanus
fused tension
complete tetanus
what happens to force when muscle fatigues
decline in maximal force of muscle
what are major causes of fatigue
ion imbalance
accumulation of lactic acid in muscle
isometric contraction
muscle remains same length as tension is produced
isotonic contraction
muscle shortens when tension is produced
