The upper-to-mid back (thoracic spine) curves outward slightly in what’s called a kyphotic curve. The lower back (lumbar spine) also has a slight inward lordotic curve.
What is the difference between spinal cord and backbone?
The spine, or backbone, is made up of a column of 33 bones and tissue going from the skull to the pelvis. These bones, or vertebrae, enclose and protect a cylinder of nerve tissues known as the spinal cord.

What are the 3 main parts of the spinal cord?
The spinal cord comprises three parts: the cervical (neck), thoracic (chest), and lumbar (lower back) regions.
Is Spinal Cord part of brain?
The base, or lower part, of the brain is connected to the spinal cord. Together, the brain and spinal cord are known as the central nervous system (CNS). Many nerves send electrical signals to and from the brain and spinal cord.
What are the 5 parts of the spine?
The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2).
What part of your spine controls your legs?
The nerves of the cervical spine control the upper chest and arms. The nerves of the thoracic spine control the chest and abdomen, and the nerves of the lumbar spine control the legs, bowel, and bladder.
Can you live without a spine yes or no?
Your spine serves many important functions, including connecting your brain to other parts of your body and providing structural support. You can’t live without a spine. Some conditions, such as SCI and spina bifida, can affect the spinal cord, leading to symptoms like partial or complete loss of movement or sensation.
What protects spinal cord?
The spinal cord is protected by bones, discs, ligaments, and muscles. The spine is made of 33 bones called vertebrae. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine.

What degree is a normal spine?
In fact, spinal curves that are less than 10 degrees are considered a normal variation of the spine. Curves that are greater than 10 degrees may be monitored (to see whether the curve is getting worse) or may need treatment.
What are 3 jobs 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.
