Document Summary
Role of different cortical regions in the control of skilled movement. Reticulospinal tract (reticular formation: lateral brainstem tract. Corticospinal tracts: lateral corticospinal tract (m1, pma, sma, ventromedial (anterior) corticospinal tract (m1, pma, sma) 3 different levels of motor control + parallel control. Motor plan: abstract representation of an intended movement, sma & pm, voluntary movement. Axons from the brain descend through the spinal cord along two major groups of. M1 + pma & sma: m1 (primary motor cortex, pma (premotor cortex area, sma (supplementary motor area) Brainstem: vestibular nucleus, tectum, reticular formation, red nucleus. 3) connections between cortex & brainstem areas. Can control the brainstem by input from the cortex area. Leaves the axons at the end and interact with motor neurons & interneurons. ++ involuntary control ++; bilaterally activate (?) Axial (i. e. trunk) & proximal muscles basic postural control. Tectospinal pathway = tectum spinal cord pathway. Postural control of axial & proximal muscles.
