Price: Free
The neurotube is the base for CNS development. The tube organization forms a continuous compartment allowing neurons to interconnect locally and through longitudinally running axons that are contained within a flexible space, the white mater.

| SC Nuclear Groups (Inside the Cord)
Price: Free
The neurotube is composed of four plates forming the spinal cord sensory and motor regions. The paired basal plates give rise to motor neuronal nuclei for flexor, extensor, gamma and sympathetic preganglionic motoneurons. The dorsal plates are sensory and are involved in receiving dorsal root ganglion axons as pathways or nuclei.

| Ascending Pathways (Inside the Cord)
Price: Free
In the spinal cord, white mater is completely surrounded by gray mater. The majority of white mater is composed of myelinated axons that course the longitudinal axis of the cord. Functional pathways for specific senses and for pain occupy consistent regions of the spinal cord as they ascend to the thalamus or the cerebellar cortex.
