As a result, those areas of the spine might break down faster. Either way, the primary axon ascends to the lower medulla, where it leaves its fasciculus and synapses with a secondary neuron in one of the dorsal column nuclei: either the nucleus gracilis or the nucleus cuneatus, depending on the pathway it took. The brain and spinal cord together make up the central nervous system (CNS). It performs the primary processing of information as it carries sensory signals from all parts of the body to the Central Nervous System through afferent fibres. Neurogenic shock lasts for weeks and can lead to a loss of muscle tone due to disuse of the muscles below the injured site. 3rd ed. But surgery can't cure arthritis, so arthritis pain in the spine may continue. [6], The grey column, (as three regions of grey columns) in the center of the cord, is shaped like a butterfly and consists of cell bodies of interneurons, motor neurons, neuroglia cells and unmyelinated axons.
