Final Answer

In the central nervous system, axons bundled together are called tracts.

Explanation

In the context of the central nervous system (CNS), axons are projections of neurons that transmit electrical impulses. When these axons are grouped together, they form structures known as "tracts." Tracts serve as pathways for signals traveling between different regions of the brain and spinal cord.

To clarify the other options:

1. Myelin Sheath: This is the fatty layer that insulates axons, enabling faster transmission of impulses, but it does not refer to the bundle itself.
2. Synapses: These are the junctions where communication occurs between neurons, involving neurotransmitter release.
3. Nerves: This term typically applies to similar structures in the peripheral nervous system, where bundles of axons are found.

Thus, the correct term for bundled axons in the CNS is tracts.
