Excitability capacity of skeletal muscle to respond to a stimulus
Extensibility ability to be stretched
Elasticity ability recoil to original shape after being stretched
fascia connective tissue located outside the epimysium
contractability ability of skeletal muscle to shorten with force
fibers fasciculi are composed of single muscle cells
perimysium loose connective tisse surrounding the facicle
Endomysium each fiber is surrounded by connective tissue sheath
Myofibrils a thread like structure the extends to each end of fiber
actin Myofiliment thin myofiliment
Actin Myofiliment resembles two mintue strands of pearls twisted together
Myosin Myofiliments thick myofiliments
Myosin Myofiliment resemble bundles of minute golf clubs
Motor Neurons nerve cells that carry action potentials to skeletal muscles
Synapse each axon branch that connects to muscle
Motor Unit a single motor neuron and all the skeletal muscle fiber it innervates
Presynaptic Terminal enlarged nerve terminal
Synaptic Cleft space between the presynaptic terminal and the muscle cell
Postsynaptic terminal the muscle fiber
Sliding filament mechanism Sliding of actin myofiliments past myosin myofiliments during contraction
Muscle twitch contraction of entire muscle
threshold a level of stimulusa muscle fiber must reach before it will respond
all-or-none response when it reaches threshold, contract maximumly
25-Lag phase time between application of a stimulus to a motor neuron
contraction phase the time of contration
relaxation phase
