Flexibility of an orthodontic wire is directly proportional to its length and the interbracket distance. Flexibility is inversely proportional to the cross-section diameter/area. Bracket prescription refers to the angles built into the brackets themselves and does not directly influence the inherent flexibility of the wire material.

The absolute refractory period occurs during the initial phase of repolarization after an action potential. During this period, the membrane is inactivated and cannot be depolarized to generate another action potential, regardless of the stimulus strength. This ensures that action potentials are unidirectional and do not propagate backward along the axon.
