1 Pick a starting location and draw the first vector to scale in the indicated direction. Label the magnitude and direction of the scale on the diagram (e.g., SCALE: 1 cm = 20 m).  Starting from where the head of the first vector ends, draw the second vector to scale in the indicated direction.
brain transmit messages to the body using neurons and spinal cord. ... Motor neurons carry messages away from the brain and back to the rest of the body. the central neurons sâ¦ystem does many jobs at the same time. It controls all voluntary movement, such as speech and walking, and involuntary movements like blinking and breathing.
These fundamental members of the nervous system also vary with respect to their functions. Sensory neurons carry signals from the outer parts of your body (periphery) into the central nervous system. Motor neurons (motoneurons) carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body. Interneurons connect various neurons within the brain and spinal cord.
