The pontine reticulospinal tract arises from two major regions in the pons. One nucleus, \(nucleus reticularis pontis oralis\), is located rostrally in the pons, extending into the midbrain; it is shown here at the level of the trigeminal motor nucleus. The other nucleus, \(nucleus reticularis pontis caudalis\), is located more caudally in the pontine tegmentum; it is shown here at the level of the abducens and facial nuclei. Both give rise to fibers that form an ipsilateral pontine reticulospinal tract, which descends somewhat medially through the brainstem tegmentum; it joins the medial longitudinal fasciculus before it enters the spinal cord."))
