The facet joints link the vertebrae together and give them the flexibility to move against each other. Each vertebra has a hole in the center, so when they stack on top of each other they form a hollow tube that holds and protects the entire spinal cord and its nerve roots.
How is the spine held together?
Bands of tissue called ligaments and tendons hold the bones of the spine, called vertebrae, in place and attach the muscles of the back to the spinal column.
What three things hold the spine together?
Low Back Supported by Lumbar Ligaments, Tendons and Muscles
The 3 major spinal ligaments are the (1) anterior longitudinal ligament, (2) posterior longitudinal ligament and (3) ligamentum flavum. Spinal tendons attach muscles to the vertebrae and together work to limit excessive movement.
What muscles hold up the spine?
The extensor muscles are attached to back of the spine and enable standing and lifting objects. These muscles include the large paired muscles in the lower back, called erector spinae, which help hold up the spine, and gluteal muscles.
What holds the vertebrae in balance?
Between each vertebral body is a cushion; the intervertebral disc. Discs absorb stresses the body incurs during movement and prevents vertebrae from grinding against one another. The intervertebral discs are the largest structures in the body without a vascular supply.
What part of the spine controls the heart?
Thoracic (mid back) – the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12.
How do you know if back pain is muscle or disc?
Your doctor can perform a neurological exam to check muscle strength, reflexes, walking ability, and the ability to feel touch. Imaging tests may be ordered to diagnose the cause of your pain. A CT scan shows cross-sectional images of the spinal column and can pinpoint a herniated disc.

What type of movement can damage the lumbar?

What absorbs shock in the spine?
The intervertebral discs are soft structures which act as shock absorbers between each of the vertebrae (bones) in the spine. A single disc sits between each vertebra. Each intervertebral disc has a strong outer ring of fibres (‘annulus’), and a soft, jelly-like centre (nucleus).
Which spinal nerves affect which parts of the body?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
