The changes in bladder control increase your risk of urinary tract infections. http://www.merckmanuals.com/professional/injuries-poisoning/spinal-trauma/spinal-trauma. Also known as the anterior spinocerebellar tract, sensory receptors take in the information and travel into the spinal cord. Internal to this peripheral region is the grey matter, which contains the nerve cell bodies arranged in the three grey columns that give the region its butterfly-shape. Costs vary with diagnosis and type of surgery for spinal stenosis. The function of lower motor neurons can be divided into two different groups: the lateral corticospinal tract and the anterior cortical spinal tract. Grey matter consists of the central canal at the centre and is filled with a fluid called CSF (Cerebrospinal fluid).

Following the closure of the caudal neuropore and formation of the brain's ventricles that contain the choroid plexus tissue, the central canal of the caudal spinal cord is filled with cerebrospinal fluid. The dural sac ends at the vertebral level of the second sacral vertebra. Scans will be needed to assess the injury. The corticospinal tract serves as the motor pathway for upper motor neuronal signals coming from the cerebral cortex and from primitive brainstem motor nuclei. Ami TR. The DL neurons are involved in distal limb control. The incomplete injury allows the injured to perform some sensory and motor functions.
