Conduction by Local Current Flow

Multiple Choice

Conduction by local current flow

A) occurs in unmyelinated fibers.
B) is faster than propagation of an action potential in myelinated fibers because myelin acts as an insulator to slow down the impulse.
C) involves current flowing locally between the active and adjacent inactive areas, thereby bringing the inactive areas to threshold so that they too become active (i.e., have an action potential) .
D) both (a) and (c) above.
E) all of these answers.
