1
New cards
excitation
nerve action potentials lead to muscle action potentials
2
New cards
excitation-contraction coupling
action potentials on sarcolemma cause activation of myofilaments, preparing them to contract
3
New cards
contraction
muscle fiber develops tension and shortens (myosin + actin binding)
4
New cards
relaxation
stimulation ends, muscle fiber relaxes
5
New cards
ligand-gated
what type of channel is the ACh receptor
6
New cards
end plate potential
depolarization in muscle fibers caused by sodium entering and potassium leaving cell
7
New cards
action potential
if threshold is reached (-65 mV), triggers adjacent voltage-gated ion channels to open, generating an ______ _________
8
New cards
cross-bridge formation
myosin head binds to active site on actin
