In the mature brain, the highest cholesterol content is found in myelin. We therefore created mice that lack the ability to synthesize cholesterol in myelin-formin … WebThe myelin sheath itself is made up of spirally arranged lamellae in which the intraperiod and dense lines alternate. Inside the myelin sheath an inner cytoplasmic process surrounds the axon and where the external surfaces of its bounding membrane come together an internal mesaxon is formed.

WebMyelinated Neuron Diagram. Myelin is a thick sheath of lipoprotein that insulates the nerve fibres of the myelinated neurons. It is not a continuous sheath and is absent at regular intervals. The region where the myelin sheath is absent is termed the node of Ranvier. Also, the segment of nerve fibre between the two nodes is termed the internode.
