Lumbar spine

Lumbar spine (lumbar, lumbar spine) consists of 5 lumbar vertebrae L (vertebrate lumbales). These are broad, kidney-shaped. The largest of the vertebrae. The last lumbar vertebra is annealed to the sacrum (os sacrum) to form the lumbosacral joints which is “filled” intervertebral plate and creates a classic up – promotorium. The lumbar spine is extremely mobile, but also the most wounding and overloading.

Lumbar vertebra is composed of:

Vertebral body (corpus vertebrae) is filled with bone marrow and abuts on the intervertebral disc (discus intervertebralis) L5 vertebral body is higher at the front than at the back
Vertebral arch (arcus vertebrae) lofty and forms together with the body space for the passage of the spinal cord
The spinal processes (processus vertebrate)
Articular processes (processus articulares) – emerge from the vertebral arch and create areas for meziobratlovému connection (articulationes intervertebrales)
Transverse processes (processus Transverse)
Spinous projection (processus spinosus) extends rearwardly, are čtverhranného shape from the flattened
Vertebrae and create space for the passage of the vascular bundle and spinal nerves.

Strength, flexibility and stability is ensured

Intervertebral discs, which are wedge-shaped
Ligaments, tendons – short ligaments provide the connection between the individual vertebrae, long ligaments connect multiple decks spine.
Intervertebral joints (articulationes intervertebrales)
muscles of the back
