Document Summary
Anat 3010 lecture 18 march 2, 2020 motor pathways in the cns (descending pathways) Descending pathways: descending pathways deliver motor instructions from the brain to the spinal cord. Motor pathways are how the brain control different aspects of movement via the cerebral cortex (or more specifically the motor cortex). This is also called the direct or corticospinal pathway. There are also indirect pathways where the cortex can exert some influence through indirectly connecting to other centers of the nervous system. The name of these pathways will always first state the source and the destination. Rubrospinal goes from the red nucleus to the spinal cord. Tectospinal goes from the tectum of the midbrain to the spinal cord. Reticulospinal goes from the reticular formation to the spinal cord. Vestibulospinal goes from the vestibular nucleus to the spinal cord. Spinal nerves attach to it: provides two-way conduction pathway, major center for reflexes.
