Quizplus · Accepted Answer

The cauda equina is a bundle of nerve roots that emerge from the inferior end of the spinal cord and extend through the vertebral canal, occupying the space inferior to the conus medullaris. The cervical and lumbar enlargements are regions of the spinal cord that have an increased diameter due to an increased number of nerve cells and serve the upper and lower limbs, respectively. The posterior median sulcus is a groove along the back of the spinal cord that divides it into left and right halves.
