There are four natural curvatures of the spine.

There is just one. It consists of the brain and spinal cord.
no . the spinal cord starts in the 1st cervical vertebra . but it is stopped in the 2nd lumber vertebra . from this site many nerve fibres come out from the cord . these are known as cauda equina . the conical shaped end of the spinal cord is called CONUS MEDULARIS
There are many, many, many different factors that can cause disabilities. For instance, if your spinal cord was damaged, you may be paralyzed from the waist down or head down, depending on where you were hit on the spinal cord. Your spinal cord sends messages to your nerves in your body, and thus cannot if broken.
33 vertebrae in the spinal cord of a human being
The spinal cord is an essential part of the central nervous system, which is in charge of many parts of the body. It also helps you utilize some of your natural reflexes.
There are two main enlargements in the spinal cord, the Cervical enlargement, and an enlargement at the Conus Medullaris in the Thorasic section of the spinal cord.
Unless you have a twin growing inside you, you only have one spinal cord. The spine however, is made up of many vertebrae. You have seven cervical, twelve thoracic, and five lumbar.
Spinal cord injuries are caused when delicate spinal cord tissue is bruised, torn, or crushed. Spinal cord injuries can be caused by accidents, but can also be caused by diseases or disorders.As many as 400,000 Americans are living with spinal cord injuries. Most spinal cord injuries occur between the ages of 16 and 30, and about 82 percent of those who experience spinal cord injuries are male. Motor vehicle accidents account for approximately 44 percent of all spinal cord injuries. Other common causes include: • Acts of violence, including those that cause knife and gunshot wounds• Slips and falls• Sports-related injuries, mostly diving accidents• Trampoline accidents Results of Spinal Cord InjuryAfter the spinal cord has been injured, messages no longer flow through the damaged area, essentially cutting off information between the brain and certain parts of the body. Generally, the functions of the body located above the point of injury will continue to work with no loss of function, while the areas of the body located below the point of injury will be impaired. Impairment can include the following: • Motor deficit• Sensory deficit• Breathing difficulty• Bowel and/or bladder dysfunction Spinal Cord Injury
In an adult the lower end of the spinal cord usually ends at approximately the first lumbar vertebra, where it divides into many individual nerve roots (L1). That is the reason Lumbar Puncture usually perform at L3-L4 in order to prevent accidentally injure to the spinal cord. The point where the spinal cord ends is referred to as the "conus medullaris"
In human anatomy, the vertebral column (backbone or spine) is a column of 24 vertebrae, the sacrum, intervertebral discs, and the coccyx situated in the dorsal aspect of the torso, separated by spinal discs. It houses the spinal cord in its spinal canal.
