After muscle damage, what guides regenerating motor neuron axons back to their former site at the neuromuscular junction?

Question

Quizplus · Accepted Answer

Basal lamina from the NMJ guides regenerating motor neuron axons back to their former site at the neuromuscular junction, providing a scaffold for the axon to grow along. Acetylcholine receptors on the muscle fibers receive input from the motor neuron axon once it has reached the NMJ and formed a synapse. Schwann cells play a role in supporting and guiding axonal growth, but they alone do not guide the axons back to the NMJ. Acetylcholine secreted by motor neurons is not involved in guiding axonal growth.
