Like the medial reticulospinal tract from the NRGc, neurons of the lateral reticulospinal tract either descend ipsilaterally or decussate in the medulla and descend contralaterally. The lateral reticulospinal tract appears to make more limited contacts at only a few spinal segmental levels at a time.

Where does the Reticulospinal tract cross?

Some of the fibers of the medullary reticulospinal tract cross to the opposite side while other descend uncrossed. These tracts terminate by entering the anterior gray column of the spinal cord and synapsing with the internuncial neurons. The reticulospinal tract contains both excitatory as well as inhibitory fibers.

What is the role of the Reticulospinal tract?

The Reticulospinal tract is responsible primarily for locomotion and postural control. The Reticulospinal tract is comprised of the medial (pontine) tract and the lateral (medullary) tract.
