SpinaI cord - Central Nervous System:
It is a long cord which arises from the medulla oblongata and runs through the vertebral column (backbone). The vertebral column protects the spinal cord. The spinal cord it also covered by meninges. A cross section of the spinal cord shows the central canal, which it filled with cerebrospinal fluid. Around the canal are clusters of cytons, which form the grey matter. The peripheral part has mainly axons and is called white matter. From each side of the spinal cord two roots, the dorsal and the ventral root, arise. The dorsal root is joined by a nerve called sensory nerve, which picks up sensations from the sense organs (receptors). From the ventral root arises the motor nerve, which takes messages from the spinal cord to the muscles or glands (effectors).
