Question

Quizplus · Accepted Answer

Basement membranes and connective tissues form a pathway and guide the regrowth of nerve fibers after injury. This pathway is called the extracellular matrix (ECM) and provides structural support for nerve regeneration. Therefore, choice A is the correct answer. None of the other options are involved in the formation of the ECM or help to guide nerve regeneration.
