What must happen before a motor unit will fire (discharge)? What occurs immediately after discharge of the motor unit?
What will be an ideal response?
ANS: In order for a motor unit to discharge, there must be sufficient facilitation (buildup of charges) at
the anterior horn cell (AHC). Once threshold is reached, an impulse is conducted down the axon
and all innervated fibers contract. Immediately after firing and fiber contraction, the motor unit
goes through latency, or a refractory period, during which depolarization cannot occur.
