1) Latent period.
DEF:period between stimulus and start of contraction.
MECH:
~propogate and generate action potential.
~causes Ca++ permeablity-cause Ca++ influx
~AP at motor end plate
~AP at muscle fiber
~contraction of muscle
2)contraction phase
sliding of actin and perforrm its work.
3)relaxation phase
relax of muscle and the muscle back to its origin.
factor causes LP.
~neuromuscular transmission
~contraction of muscle
~movement of lever
factor affecting of SMT
~type of muscle fiber
