Corticopontocerebellar Pathway
|
Originantes in the primary motor cortex & premotor cortex. (Cortex to pons to cerebellum)
|
|
Information to the cerebellum from the corticopontocerebellar pathway is what?
|
It is a copy of the motor plan from the primary and premotor cortex.
|
|
Olivocerebellar tract
|
directs information from the inferior olive nucleus to all parts of the cerebellum.
|
|
Information to the cerebellum from the olivocerebellar tract is what?
|
It is a copy of the motor plan from the cortex, basal ganglia, spinal cord, and reticular formation.
|
|
Vestibularcerebellar fibers
|
Originate in the vestibular aparatus and vestibular nuclei and travel to the flocculonodular lobe and fastigial nucleus in the cerebellum.
|
|
Vestibular fiber connections are very important for.......
|
maintenance of equilibrium.
|
|
Dorsal Spinocerebellar tracts
|
Transmit somatic sensory info from the muscle spindles golgi tendon organs, and joint receptors to the cerebellum.
|
|
Dorsal spinocerebellar tracts send what to the cerebellum?
|
Sends feedback of somatosensory information (muscle stretch, muscle tension, and joint position in space).
|
|
Ventral spinocerebellar tarcts
|
Transmit a copy of motor plan that actually arrived to the anterior motor neurons.
|
|
Together the dorsal and ventral help the cerebellum compare what?
|
Helps the cerebellum compare the intended motor plan from the cortex to what actually is received at the anterior motor neurons and compares how well the motor plan was executed.
