Question 20

Briefly identify the role of the following structures in controlling voluntary skeletal movement: cerebellum, primary motor cortex, premotor cortex, pyramidal tracts, inferior olivary nucleus, and cerebral and cerebellar peduncles.

Accepted Answer

The premotor cortex and primary motor cortex of the frontal lobe of the cerebrum sequence and coordinate voluntary contraction of skeletal muscles. Pyramidal neurons of the cortex relay impulses to specific muscle groups. These pyramidal tracts (axons) descend through the brain stem and continue down the spinal cord. However, in the midbrain, these tracts will pass through the cerebral peduncles, which will simultaneously relay descending impulses to the cerebellum. Then the superior cerebellar peduncles will direct impulses in the reverse direction, back toward the pre-motor cortex of the cerebrum. At the same time the cerebellum also receives proprioceptive sensory information via the inferior olivary nucleus of the medulla, and it compares actual body movements to the intended movement generated by the cerebrum. The cerebellum is responsible for constantly refining the actual movement to achieve the intended movement.
