Filament Theory Flashcards
Action potential
Action potential is sent from the central nervous system down to the neuron
Acetylcholine
Acetylcholine is released at the neuromuscular junction
Neuromuscular junction
The end plates of the neuromuscular junction depolarises
Synaptic cleft
Acetylcholine goes through the synaptic cleft
Depolarises
Acetylcholine causes cell to depolarise
Calcium
The cell depolarises causing calcium to be released from sarcoplasmic reticulum
Troponin
Calcium then bonds with troponin
Tropomyosin
Troponin depolarises into tropomyosin which moves away from actin
Crossbridge
Actin and myosin bi da causing crossbridge
ATP
Adenosine triphosphate is broken down and loses a phosphate
ATPase and ADP
ATPase is an enzyme which breaks down atp into adp
Actin and myosin
Actin and myosin pull together causing a muscle contraction
