Spinal cord - Wikipedi

The spinal cord is a long, fragile tubelike structure that begins at the end of the brain stem and continues down almost to the bottom of the spine. 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 is the part of the central nervous system that is found within the spinal canal of the vertebral column.The cord extends from the corticomedullary junction at the foramen magnum of the skull down to the tip of the conus medullaris within the lumbar cistern.. It is lined by spinal pia mater and contained by the other spinal meninges in the thecal sac The spinal cord is a slender column of nervous tissue that passes downward from the brain into the vertebral canal. Although continuous with the brain, the spinal cord begins where nervous tissue leaves the cranial cavity at the level of the foramen magnum. The spinal cord is not uniform in diameter along its length

Spinal cord compression can result from a myriad of both atraumatic and traumatic causes. The spinal column, comprised of numerous soft tissue and bony structures, is built to provide the body's structural support and protect the spinal cord and exiting nerve roots. The encased spinal cord depends upon this stability. However, it is simultaneously vulnerable to a variety of compressive. The spinal cord itself has neurological segmental levels which are defined by the spinal roots that enter and exist the spinal column between each of the vertebral segments.

Spinal cord tumors are tumors that form on the spinal cord or in the area around it. A spinal cord tumor may be cancerous (malignant) or noncancerous (benign). Even if benign, a tumor often causes pain and discomfort because it pushes on the spinal cord or nerves. A spinal cord tumor may be called primary, which means the cancer started. Spinal cord compression happens when pressure on the spinal cord stops the nerves working normally. Spinal cord compression is an emergency and needs to be treated quickly. Contact your doctor straight away if you have any symptoms of spinal cord compression Spinal cord injury (SCI) in children is a rare injury that can result in permanent loss of motor and sensory function, and dysfunction of the bowel and bladder.

Spinal Cord Injuries (SCIs) are a significant cause of disability, with profound—and in many cases devastating— consequences. According to recent data, about 12,000 SCIs occur annually in the United States, and up to 250,000 Americans are living with SCIs. Most victims are aged 16 to 30; more than 80% are males Complete spinal cord injury is the complete sensory and motor loss below the site of spinal cord injury following acute or chronic destruction, compression, or ischemia of the spinal cord. Initially, this may present as spinal shock , which is an acute physiological loss or depression of spinal cord function The spinal cord is the elongated portion of the central nervous system (CNS) that connects the brain to all muscles of the body and most sensory nerves to the brain. 1 It is surrounded and protected by vertebrae, or the spinal column. The outer edge of the spinal cord is the white matter (), which contains the branching portions of nerve cells known as axons Spinal Cord Injury Definition Spinal cord injury is damage to the spinal cord that causes loss of sensation and motor control.

The Spinal Cord Pathway. Your spinal cord is a bundle of nerves about 18-inches long that runs down the middle of your back. It extends from the base of the brain down to somewhere near your waist. The nerves within the spinal cord constitute a pathway that carries messages back and forth from your brain to all parts of your body Lumbar spinal cord injury levels (L1-L5) The lumbar region of the spine is located immediately below the thoracic vertebrae and is a common area for injuries. Chronic lower back pain is one of the most prevalent medical complaints in modern society today. Injuries to the spinal cord can be complete or incomplete and affect both or just one side. Unfortunately, there are at present no known ways to reverse damage to the spinal cord. However, researchers are continually working on new treatments, including prostheses and medications, which may promote regeneration of nerve cells or improve the function of the nerves that remain after an SCI. SCI treatment currently focuses on preventing further injury and empowering people with an SCI. The segment of the spinal cord will be much higher than the vertebra as the spine lengthens, causing the spinal nerves to descend in order to exit Injuries of a certain spinal nerve will likely injure a segment further down. What's worse- cutting the spinal nerve or the spinal segment The Spinal Cord Injury Research Evidence (SCIRE) Project is dedicated to providing up-to-date, accurate information about the effects of rehabilitation for people with SCI. SCIRE staff review and rate the research on spinal cord injury and put the results on the web - eliminating the need to search and screen individual databases

The team produced the following guideline: For important fitness benefits, adults with a spinal cord injury should engage in at least 20 min of moderate to vigorous intensity aerobic activity. The goal of decompression surgery is to relieve the pressure on the spinal cord and/or spinal nerves. This can be accomplished by removing damaged structures (eg, herniated disc, bone fracture) or soft tissues pressing on the cord and nerves—thereby creating space around these neural elements. Different types of decompression procedures exist.
