Respuesta :
The spinal cord is partitioned into an inner gray matter region, and an outer white matter region.
The most crucial element joining the body and the brain is the spinal cord. The first or second lumbar vertebral level is where the spinal cord joins the medulla, which is where it extends from the foramen magnum. It is a crucial link that connects the body and the brain in both directions. The spinal cord measures 1 to 1.5 cm in diameter and 40 to 50 cm in length. On each of its sides, two rows of nerve roots follow one another. 31 pairs of spinal nerves are created as a result of the distal fusion of these nerve roots. The spinal cord is a cylinder-shaped mass of evenly distributed white and gray matter in the neurological system.
