Spinal Cord:The spinal cord is part of the central nervous system that extends from the base of the brain through the vertebral canal to transmit nerve signals between the brain and body.
Motor Neurons:Motor neurons are nerve cells that originate in the central nervous system and send impulses specifically to muscles or glands to trigger movement or secretion.
Sensory Neurons: Sensory neurons are nerve cells responsible for converting external stimuli from the organism's environment into internal electrical impulses for sensory information processing
