Spinal Cord News

The spinal cord is a vital part of the central nervous system, housed within the vertebral column of the spine. It extends from the brainstem down the back and acts as a major conduit for transmitting information between the brain and the rest of the body. Structurally, the spinal cord is made up of nerves that carry incoming sensory data to the brain and outgoing motor commands to the muscles. It is segmented into different regions corresponding to the nerve roots that branch off to innervate specific parts of the body. These regions include the cervical, thoracic, lumbar, and sacral areas. The spinal cord also plays a critical role in reflex actions, which are immediate responses to certain stimuli that do not require direct involvement from the brain. Damage to the spinal cord can lead to significant impairments like paralysis and loss of sensation below the site of injury, reflecting its crucial role in bodily functions.
