13.11 Pontine and Medullary Reticulospinal Tracts

The pontine reticulospinal tract arises from the pontine motor reticular centres (Figure 13.2). The medullary reticulospinal tract arises from the medial medullary motor reticular centres, and is strongly inhibitory on gamma neurons in the ventral horn of the spinal cord (Figure 13.2).

The reticulospinal tracts have projections from one side of the midline to the other and therefore can be regarded as a midline system. Figure 13.2 shows an initial decussation of the reticulospinal tracts, arising from the pontine and medial medullary reticular motor centres; the subsequent projections from side to side have been omitted.
