Which of the following describes the characteristic of nerve impulse conduction in a neuron?

AConducted only from axon to terminal unidirectionally

BAction potentials in different fibers of a nerve trunk do not interfere with each other

CCan conduct excitation normally as long as the structure is intact

DIs unaffected by changes in internal environmental factors

Correct answer: B. Action potentials in different fibers of a nerve trunk do not interfere with each other

The action potentials in different fibers of a nerve trunk can conduct independently without interfering with each other.
