What is special about the spinal cord?

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.

What does a spinal cord do?

What does the spinal cord allow the body to do? When the body moves, messages travel from the brain down the spinal cord. Messages also are carried up the spinal cord to the brain so a person can feel sensations. There are nerves that branch off the spinal cord.

What are the 3 functions of the spine?

The three main functions of the spine are to:

  • Protect the spinal cord, nerve roots and several of the body’s internal organs.
  • Provide structural support and balance to maintain an upright posture.
  • Enable flexible motion.

    What are two facts about the spinal cord?

    Here are some spinal cord facts:

    • The spinal column of stacked vertebrae creates a hollow spinal canal through which the spinal cord runs from the brain to the first lumbar vertebra.
    • At that point, the cord’s fibers separate but continue into the lumbar region and eventually reach the tailbone.

    What are the 3 functions of the spinal cord?

    What does the spinal cord do?

    • Motor Functions – directs your body’s voluntary muscle movements.
    • Sensory Functions – monitors sensation of touch, pressure, temperature and pain.
    • Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).

      What part of the body does the spinal cord control?

      The spinal cord itself is a long bundle of nerve cells encased in the 33 vertebral bones known individually as vertebra. The spinal cord is the body’s central processing center, receiving information from the brain and sending it to branching nerves that connect with every other area of the body.

      What happens if your spinal cord is damaged?

      When the spinal cord is damaged, the message from the brain cannot get through. The spinal nerves below the level of injury get signals, but they are not able to go up the spinal tracts to the brain. Reflex movements can happen, but these are not movements that can be controlled.

      How long is your spinal cord?

      The spinal cord is about 18 inches (45 centimeters) in length and is relatively cylindrical in shape. The cervical (neck) and lumbar (lower back) segments house the spinal cord’s two areas of enlargement. A fibrous band called the filum terminale begins at the tip of the conus medullaris and extends to the pelvis.
