The Functions Of The Myelin Sheath Write a short note on myelin sheath and the process of myelination of a peripheral nerve fiber. Answer. The thick axons of peripheral nerves are surrounded by myelin sheath, which is made up of concentric layers of plasma membrane of Schwann cells and lipids (fatty substance) between these layers. It is formed by Schwann cells by a … [Read more...] about The Functions Of The Myelin Sheath

Reflex Action: Types, Mechanism, Examples, And Diagram Question 1. What are the nodes of Ranvier and the incisures of Schmidt–Lanterman? Answer. In myelinated nerve fibers, the myelin sheath is segmented. These segments are separated at regular intervals by nodes of Ranvier. The incisures of Schmidt–Lanterman are oblique clefts in the myelin sheath and act as conduction … [Read more...] about Reflex Action: Types, Mechanism, Examples, And Diagram
