The vectors in a subset S ={ v 1, v 2 ,..., v n } of a vector space V are said to be linearly dependent, if there exist a finite number of distinct vectors v 1, v 2, ..., vk in S and scalars a 1, a 2, ..., ak, not all zero, such that.
spinal cord - a major part of the central nervous system which conducts sensory and motor nerve impulses to and from the brain; a long tubelike structure extending from the base of the brain through the vertebral canal to the upper lumbar region.
It is a superhighway for messages between the brain and the rest of the body. The spinal cord is surrounded for most of its length by the bones (vertebrae) that form the spine. The human spinal cord, part of the central nervous system, is generally around 17 inches long, and extends from the brain to the lower back.Your spinal cord is protected by the vertebral column (also known as the spinal column or backbone).The human spinal column is made up of 33 bones - 7 vertebrae in the cervical region, 12 in the thoracic region, 5 in the lumbar region, 5 in the sacral region and 4 in the coccygeal region.t is a superhighway for messages between the brain and the rest of the body.
