A basketball player is about to shoot for the final winning point in the game. Please describe the path that neurons would send signals through to allow him to 1) see the hoop in front of him/ aim and 2) throw the ball with his arm.
sensory neurons in eyes --> Spinal cord -->
Brain---> spinal cord ---> Motor neurons in arm muscles
