Spinal Cord Function and Anatomy The spinal cord is a cylindrical shaped bundle of nerve fibers that is connected to the brain at the brain stem. The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. The brain and spinal cord are the major components of the central nervous system (CNS).

- The spinal cord is the most important structure between the body and the brain. The spinal cord extends from the foramen magnum where it is continuous with the medulla to the level of the first or second lumbar vertebrae. It is a vital link between the brain and the body, and from the body to the brain. The spinal cord is 40 to 50 cm long and 1 cm to 1.5 cm in diameter. Two consecutive rows of nerve roots emerge on each of its sides. These nerve roots join distally to form 31 pairs of spinal nerves.

Spinal cord The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS).

Spine Basics The nerves in each area of the spinal cord connect to specific parts of your body. This is why damage to the spinal cord can cause paralysis in certain areas and not others -- it depends on which spinal nerves are affected. The nerves of the cervical spine go to the upper chest and arms.

What does the spinal cord do? The peripheral nervous system is the network of nerves strands that branch off from the left and right sides of the spinal cord through openings between each vertebra on the spinal canal. These nerve pairs spread throughout your body to deliver commands from your brain and spinal cord to and from parts of your body.

About The Brain and Spinal Cord The brain stem connects the brain with the spinal cord.

- The spinal cord is the main route for information to be transported to the brain from the peripheral nervous system. Together with the brain, the spinal cord composes the central nervous system. The cord resides within a tunnel of bones called vertebrae. The vertebrae help protect this vital part of the human anatomy. The spinal cord is divided into three main sections, each controlling specific parts of the body.

- A. SPINAL CORD ANATOMY. The spinal cord is continuous with the brain, together forming the central nervous system. List its three basic functions. 1. The spinal cord and its associated spinal nerves contain neuronal. circuits that mediate spinal reflexes. 2.The spinal cord is the site for integration (summing) of nerve impulses that arise locally or arrive from the periphery and brain.3. The spinal cord provides the pathways by which sensory nerve impulses reach the brain and motor nerve impulses pass from the brain to motor neurons.he spinal cord is continuous with the brain, together forming the central nervous system.

Spinal Cord The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The length of the spinal cord is much shorter as compared to the length of the vertebral column.

Spinal cord The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS). The spinal cord begins at the occipital bone and extends down to the space between the first and second lumbar vertebrae; it does not extend the entire length of the vertebral column.

- The nerves, spinal cord and brain work together to keep you aware of what's going on with the body and get messages out to the muscles and other body systems. Not all nerve me…ssages are handled by the brain though and so not all involve the spinal cord, the main path way to the brain from the body's nerves.

- The spinal cord, on the other hand, is a long bundle of nerve tissue about 18 inches long and ¾ inch thick. It extends from the lower part of the brain down through spine. Along the way, various nerves branch out to the entire body. These make up the peripheral nervous system. Both the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by the set of ring-shaped bones called vertebrae that make up the spine.

About The Brain and Spinal Cord Together, the brain and spinal cord form the central nervous system. This complex system is part of everything we do. It controls the things we choose to do -- like walk and talk -- and the things our body does automatically -- like breathe and digest food.

Spinal cord The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS).n the upper part of the vertebral column, spinal nerves exit directly from the spinal cord, whereas in the lower part of the vertebral column nerves pass further down the column before exiting. The terminal portion of the spinal cord is called the conus medullaris.

- Spinal cord injury. The spinal cord is part of your central nervous system. It is a thick bundle of nerves that runs from your brain, down through the neck and spine, inside a canal of vertebrae. Its main function is to transmit signals to and from the brain and body. For example, the spinal cord passes nerve signals, such as hot or cold sensations, back to the brain.

Spinal cord The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS).or the nerves of the lower spinal cord, this means that they exit the vertebral column much lower (more caudally) than their roots. As these nerves travel from their respective roots to their point of exit from the vertebral column, the nerves of the lower spinal segments form a bundle called the cauda equina.

- The brain and spinal cord are referred to as the Central Nervous System, whilst the nerves connecting the spinal cord to the body are referred to as the Peripheral Nervous System. The nerves within the spinal cord are grouped together in different bundles called Ascending and Descending tracts.

These bones protect the spinal cord. Like the brain, the spinal cord is covered by the meninges and cushioned by cerebrospinal fluid. Spinal nerves connect the brain with the nerves in most parts of the body.

- Spinal Nerves. Nerves called the spinal nerves or nerve roots, branch off the spinal cord and pass out through a hole in each of the vertebrae called the foramen. These nerves carry information from the spinal cord to the rest of the body, and from the body back up to the brain.oth the nerves and the segments in the spinal cord are numbered in a similar way to the vertebrae. The point at which the spinal cord ends is called the conus medullaris, and is the terminal end of the spinal cord. It occurs near lumbar nerves L1 and L2.

Overview of Spinal Cord Disorders The spinal cord is the main pathway of communication between the brain and the rest of the body. It is a long, fragile, tubelike structure that extends downward from the base of the brain. The cord is protected by the back bones (vertebrae) of the spine (spinal column).

Medical Definition of Spinal cord Spinal cord injury: Trauma or damage to the spinal cord, the major column of nerve tissue that is connected to the brain and lies within the vertebral canal and from which the spinal nerves emerge. The spinal cord and the brain constitute the central nervous system. The spinal cord consists of nerve fibers that transmit impulses to and from the brain. Like the brain, the spinal cord is covered by three connective-tissue envelopes called the meninges.

- Brain stem: The brain stem is the lower part of the brain that connects to the spinal cord. It contains bundles of very long nerve fibers that carry signals controlling muscles and sensation or feeling between the cerebrum and the rest the body.
