Describe the Function of Schwann Cells
The Schwann cell plays a vital role in maintaining the peripheral nervous system PNS. The conduction of nerve impulses across axons nerve growth and regeneration trophic support for neurons production of the nerve extracellular matrix regulation of neuromuscular synaptic function and. Schwann Cells Video Organ Systems Khan Academy The Schwann cells do not degenerate. . When motor neurons are severed causing nerve terminals to degenerate Schwann. Schwann cells are derived from the neural crest and play crucial roles in the maintenance and regeneration of the motor and sensory neurons of the. The neurilemma assists in regeneration of an axon when it is damaged by forming a regeneration tube to stimulate and guide its regeneration. They also secrete proteins such as laminin and collagen and cell adhesion molecules involved in binding with other cells to support the regeneration process. As the neuron recovers its axon grows i...
