Solution

In the context of the spinal cord anatomy, the funiculi, which are the major divisions of white matter, primarily contain nerve tracts.

Explanation:

  1. Motor Fibers: While some motor fibers are present, they are primarily found in specific tracts rather than being a characteristic of the funiculi as a whole.
  2. Nerve Tracts: Funiculi are composed of bundles of nerve fibers (tracts) that transmit sensory and motor information throughout the nervous system.
  3. Gray Synapses: The funiculi themselves do not contain gray matter or synapses; these are found in the gray matter of the spinal cord.
  4. Sensory Fibers: Although sensory fibers are present in certain tracts within the funiculi, the term "nerve tracts" more broadly encapsulates the composite of both motor and sensory pathways.

Thus, if selecting from the choices provided, the correct answer is nerve tracts.
