What are the primary components of the gray matter in the spinal cord?

• Myelinated nerve fibers
  

• 
  Nerve cell bodies, dendrites, and unmyelinated axon terminals
  

• 
  Commissure fibers and connective tissue
  

• Muscle fibers and epithelial cells

The central canal of the spinal cord runs through which part of the gray matter?
