Sentences with word «corticospinal»
The word "corticospinal" refers to a connection between two important parts of the nervous system: the cerebral cortex (the outer layer of the brain responsible for thinking and movement) and the spinal cord (a long bundle of nerves that helps transmit signals between the brain and the body).
