The Supplementary Motor Area of the Brain

  The motor cortex is a neocortical region in charge of directing each of our movements. It’s located in the frontal lobe and is made up of the primary motor cortex, the premotor cortex, and the supplementary motor area. In this article, we’re going to focus on this last-mentioned area. We’ll review its component parts, its functions, and the alterations it might suffer as a result of injury or other types of affectations. Supplementary motor area The supplementary motor area (SMA) occupies the posterior third of the superior frontal gyrus and coordinates postural movements. Its neurons project to the spinal…
