The PRF descends the reticulospinal tract where it innervates motor neurons and spinal interneurons.
2.
The vestibulospinal tract, as well as reticulospinal tracts are examples of components of the medial pathway.
3.
These are the rubrospinal tract, the vestibulospinal tract, the tectospinal tract and the reticulospinal tract.
4.
Commands that initiate locomotor circuits in the spinal cord are also transmitted through the medullary reticulospinal tract.
5.
Facilitatory signals arrive through the ventral reticulospinal tract from Brodmann area 4, the neocerebellum and the vestibular nucleus.
6.
Inhibitory signals arrive at gamma neurons through the lateral reticulospinal tract from Brodmann area 6, the paleocerebellum and the red nucleus.
7.
Thus, the reticulospinal tracts are involved in many aspects of motor control, including the integration of sensory input to guide motor output.
8.
Hyperextension occurs due to facilitation of the anterior reticulospinal tract caused by the inactivation of inhibitory corticoreticular fibers, which normally act upon the pons reticular formation.
9.
These convey an impulse to neurons in the medullary reticular formation which project down the reticulospinal tract and synapse with afferent nerve fibers in the spinal cord ( L1-L6 ).
10.
The RVLM is a primary regulator of the sympathetic nervous system; it sends catecholaminergic projections to the sympathetic preganglionic neurons in the intermediolateral nucleus of the spinal cord via reticulospinal tract.
