Concept explainers
Introduction:
The general senses are received from head and all parts of the body from the thalamus and it process the signals and send the output to the postcentral gyrus. Then, they are processed by the primary somatosensory cortex and the somatosensory association areas and the processed output is send to the opposite side of the body. The 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 the somatotopy, so that the functions are located on the opposite side of the body.
