TRUE or FALSE
-When viewed under polarized light, the dark staining bands are the A bands.
-The Z line is comprised of thick filaments attached to interconnecting proteins, delineating the ends of the sarcomere.
-Light staining areas of a muscle fiber viewed under polarized light are called I bands.
-The expanded portion of the axonal branch that faces a region of the sarcolemma is called a synaptic terminal.
-A space that separates the expanded tip of the axon at the neuromuscular synapse from the motor end plate is the synaptic vesicle.
-The sarcoplasmic reticulum conducts action potentials that spread across the sarcolemma into the cell.
-A muscle that opposes the action of a prime mover is a synergist.
-A muscle that assists a prime mover is an agonist.
-The fulcrum lies between the applied force and the resistance in a first-class lever.
