Ascending tracts and descending tracts send and transmit signals from the brain respectively to various nerve cells across the body. The spinal cord is divided into five different parts. [16] Impaired blood flow through these critical radicular arteries, especially during surgical procedures that involve abrupt disruption of blood flow through the aorta for example during aortic aneurysm repair, can result in spinal cord infarction and paraplegia.

Baron EM, et al. Uncommon cause of lumbar spinal stenosis is due to spinal epidural lipomatosis, a condition where there is excessive deposit of fat in the epidural space, causing compression of nerve root and spinal cord. Wear a seat belt every time you're in a moving vehicle. Below L2, the proprioceptive information travels up the spinal cord in the ventral spinocerebellar tract. A steroid, methylprednisolone, can be of help as can physical therapy and possibly antioxidants.

Spinal block can block the nerve of the arms, legs, neck, and buttocks, but the doctor gives the injection at the lumbar, so the arms and neck are not blocked. This induces the roof plate to begin to secrete BMP, which will induce the alar plate to develop sensory neurons.

The disks that cushion vertebrae may compress with age or injury, leading to a herniated disk. Nerve tissue consists of the grey and white matter spread across uniformly. [11] Meanwhile, the overlying ectoderm secretes bone morphogenetic protein (BMP). Numbness or paralysis can be immediate or come on gradually. The major contribution to the arterial blood supply of the spinal cord below the cervical region comes from the radially arranged posterior and anterior radicular arteries, which run into the spinal cord alongside the dorsal and ventral nerve roots, but with one exception do not connect directly with any of the three longitudinal arteries.
