The Spine Diagramsoft discs,the spinal cord, and spinal nerves. The spine anatomy is a complex structure. Simply put: the vertebrae, which stack like spools of thread, support the back and protect the spinal cord. In turn, the spinal cord relays essential information between the brain and the body. SPINE DIAGRAM
The Ligaments and MusclesHolding the vertebrae together in a column are the ligaments and muscles, which also control back movement. The back has three natural curves which form an S-shape when viewed from the side. this helps to balance and distribute the weight of the body on the legs.Traduction "libre" de Google: Merci de votre indulgence! Cervical Spine DiagramStress in the spine is greatest in the cervical (neck) and lumbar (lower back) areas. These two regions are responsible for most of the movement in the back, allowing you to bend and twist. The thoracic spine allows little movement and therefore is injured less often. The lumbar curve of the lower spine supports the greatest body weight and is the most vulnerable to injury and pain. Your spinal column is made up of 24 vertebrae not including the Sacral or Coccygeal. They are:7- Seven in the neck (cervical spine), 12- Twelve in the midback (thoracic spine) and 5- Five in the lower back (lumbar spine). The spinal cord inside your spinal column, is made up of billions of nerves and is protected by bone all around it. Its nerves branch out through openings between the vertebrae and connect to the body's internal organs, muscles, joints, ligaments, tendons and other parts. This connection is vital for our well-being. The spine diagram below shows each of those vertebrae and indicates the functions of the spinal cord related to it.
