Is the spine a single fused bone?

Is the spine a single bone?

The spine is made of 33 individual bones stacked one on top of the other. This spinal column provides the main support for your body, allowing you to stand upright, bend, and twist, while protecting the spinal cord from injury.

What are the spine bones called?

Your spine is made up of 24 small bones (vertebrae) that are stacked on top of each other to create the spinal column. Between each vertebra is a soft, gel-like cushion called a disc that helps absorb pressure and keeps the bones from rubbing against each other.

What is L7 in the spine?

The seventh lumbar vertebra (L7) or its caudal articular processes are considered the most frequent sites of fractures, with fracture occurring more commonly than dislocation (Flatt et al., 1974).

What are the five parts of the spine?

The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.

What aggravates facet joint pain?

Pain is often aggravated by leaning back (extension) and/or twisting (rotation) of the neck or back, and can be relieved by bending forward (flexion). Cervical facet pain can cause pain when turning the head while driving or difficulty at night relaxing the neck when lying down.

What is the main function of the facet joints?

Small joints located between and behind adjacent vertebrae. There are two facet joints at each level of the vertebral column, providing stability to the spinal column while allowing movement. They are found at every spinal level, except at the top level of the cervical spine.

What are the 3 types of joints?

The adult human skeletal system has a complex architecture that includes 206 named bones connected by cartilage, tendons, ligaments, and three types of joints:

  • synarthroses (immovable)
  • amphiarthroses (slightly movable)
  • diarthroses (freely movable)
