NEET PG DENTAL EXAM

Detailed explanation-1: -In addition, Schwann cells induce axon regeneration and nerve cell survival by increasing the expression of a wide variety of growth factors. They also secrete extracellular matrix molecules, such as laminin and collagen, and cell adhesion molecules to support the regeneration process.

Detailed explanation-2: -Following the formation of the synapses, Schwann cells modulate synaptic activity at the NMJ. Schwann cells also play critical roles in reinnervation of the muscle after nerve injury; they extend their processes to induce and guide axonal sprouts for re-establishing neuromuscular synapses.
