WebThe rubrospinal tract mainly functions to facilitate flexors of the limbs, whereas the pontine and medullary reticulospinal tracts have either a facilitative (pontine) or inhibitory (medullary) effect on the extensors. The corticospinal tracts (cell bodies in the cerebral cortex) are most important for voluntary movement in primates. Web4 jul. 2024 · The lateral reticulospinal tract, otherwise known as the medullary reticulospinal tract, contains fibres which originate from the medulla. They have what is described by Netter as a "flexor bias". Unlike the anterior (pontine) tract, the medullary upper motor neurons are heavily influenced by cortical input.

The descending tracts are: - for standing posture: pontine reticulospinal & lateral vestibulospinal (both run in the spinal ventral funiculus) - for voluntary movements: corticospinal, rubrospinal, and medullary reticuospinal tracts ...
