The commissural fibers or transverse fibers are axons that connect the two hemispheres of the brain. In contrast to commissural fibers, association fibers connect regions within the same hemisphere of the brain, and projection fibers connect each region to other parts of the brain or to the spinal cord.

WebOct 11, 2024 · Myelin has properties of low capacitance and high electrical resistance which means it can act as an insulator. Therefore, myelin sheaths insulate axons to increase the speed of electrical signal conduction. This allows myelinated axons to conduct electrical signals at high speeds. WebThe myelin sheath, a living compacted membrane duplicature from a glial cell, helps to control the developmental, anatomical, and molecular differentiation of the axon into nodal, paranodal, juxtaparanodal, and undifferentiated internodal segments and isolates some segments of the axon electrically so that saltatory conduction becomes possible.
