Question
Chapter 14.5, Problem 9AYLO
Summary Introduction
To discuss:
Locations of the precentral gyrus and motor association area; their roles in motor control, the somatotopy of the gyrus as charted in the motor homunculus, and the effect of decussation on its function.
Introduction:
Skeletal contractions are planned in the motor association area, and the signals are sent to the precentral gyrus and then to the brainstem and spinal cord. The precentral gyrus exhibits somatotopy, such that its functions are located on the opposite side of the body.
