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).
Schwann cells: these cells provide the myelin that covers neurons in the peripheral nervous system. Larger neurons are covered in a myelin sheath. Myelin is high in lipid and serves the same purpose as insulation around electrical wires.Myelinated axons conduct nerve impulses faster.hese cells form the substance of the brain, spinal cord, and peripheral nervous system. The brain is composed of the basic units of the cerebral hemispheres, brainstem, and cerebellum. The cerebral hemispheres can be further categorized by structure and function.
