Spinal Cord:The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column, acting as a major conduit for information traveling between the brain and the rest of the body.
Motor Neurons:Motor neurons are nerve cells in the central nervous system that control movements by transmitting signals from the brain and spinal cord to muscles, initiating contraction.
Sensory Neurons: Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses for sensory input
