Spinal Cord

In addition to motor neurons, spinal components of the motor system include sensory pathways, the proprioceptive system, and central pattern generators (CPGs). Sensory afferents bring information to the CNS from the skin, joints, and muscles, and both cells and fiber tracts in the spinal cord relay that information to structures involved in motor control. For example, primary afferent neurons terminate on the dorsal column nuclei in the medulla, which relay that information to the thalamus through a fiber pathway called the medial lemniscus. In addition, an extensive and intricate system of intrinsic spinal cord neurons underlies a group of miscellaneous functions collectively termed proprioceptive. Proprioceptors are sensory transducers in muscles, tendons, and other internal tissues. However, the concept of the proprio-ceptive system extends beyond this definition to include a wide variety of interneurons that relay somatosensory signals locally and between segments in the spinal cord as well as carry descending motor commands, largely within the spinal cord. CPGs are neural networks that generate patterned, rhythmic movements, such as those involved in walking and running.
