Your spinal cord is a cylinder-shaped tube of tissue that runs through the center of your spine, from your brainstem to your lower back. It’s made of nerves and cells that carry messages from your brain to the rest of your body.

The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the lower brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals. The center of the spinal cord is hollow and contains a structure called the central canal, which contains cerebrospinal fluid.

It’s made up of your brain, spinal cord and nerves. Your nervous system works by sending messages, or electrical signals, between your brain and all the other parts of your body. These signals tell you to breathe, move, speak and see, for example.

2023年11月3日 · Each segment of the spinal cord provides several pairs of spinal nerves, which exit from vertebral canal through the intervertebral foramina. There are 8 pairs of cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal pair of spinal nerves (a total of 31 pairs). Learn more about the spinal cord with our learning material.

The spinal cord consists of bundles of nerve axons forming pathways that carry incoming and outgoing messages between the brain and the rest of the body. The spinal cord contains nerve cell circuits that control coordinated movements such …

2024年4月4日 · The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.

2025年1月22日 · The spinal cord is a cylindrical structure composed of nervous tissue, serving as the primary communication pathway between the brain and the peripheral nervous system. It is well-protected by the vertebral column and surrounded by several protective layers.

2024年8月7日 · The spinal cord is a cylindrical tube of nerves and other cells. It carries signals back and forth between the brain and the rest of the body. Learn more about its anatomy and functions.

The spinal cord is part of the central nervous system (CNS), which extends caudally and is protected by the bony structures of the vertebral column. It is covered by the three membranes of the CNS, i.e., the dura mater, arachnoid and the innermost pia mater.

2025年1月21日 · The spinal cord is an elongated cylindrical structure, about 45 cm (18 inches) long, that extends from the medulla oblongata to a level between the first and second lumbar vertebrae of the backbone. The terminal part of the spinal cord is called the conus medullaris.
