1 Medullary body: 2  the 'white matter' of the cerebrum; consists of myelinated axons. 3  types of axons include: 4  commissural fibers-conduct impulses between cerebral hemispheres (and form the corpus callosum). 5  projection fibers-conduct impulses in & out of the cerebral hemispheres.ike the brain, the spinal cord consists of gray matter and white matter. The gray matter (cell bodies & synapses) of the cord is located centrally & is surrounded by white matter (myelinated axons).
myelin. the lipid substance forming a sheath (the myelin sheath) around the axons of certain nerve fibers; it is an electrical insulator that serves to speed the conduction of nerve impulses in these nerve fibers, which are called myelinated or medullated fibers. adj., adj myelinÂ´ic.yelinated nerve fibers occur predominantly in the cranial and spinal nerves and compose the white matter of the brain and spinal cord. It is the myelin sheath that gives the whitish color to the areas of white matter.
