Because the lumbar spine has no spinal cord and has a large amount of space for the nerve roots, even serious conditions—such as a large disc herniation—do not typically cause paraplegia (loss of motor function in the legs). In This Article: Spinal Anatomy and Back Pain Vertebrae in the...
The spinal cord has a small diameter, it lies within a rigid bony canal and it contains important neural elements. Therefore, relatively small lesions within the parenchyma or in the extraaxial space often present with serious neurologic deficits. For these reasons, imaging of the spine and ...
The bones in the spinal column surround and protect the spinal cord, which runs behind the vertebral bodies in a canal from the neck down to the top of the lumbar spine. 脊柱的骨围绕并保护脊髓。脊髓走行于椎体后方的椎管内,上自颈部下到腰椎的顶...
Cervical laminectomy:To remove excessive pressure from nerve roots, your surgeon will remove a portion of the vertebral bone called the lamina to make more room for your spinal cord and spinal nerve. Posterior Microdiscectomy:Using a microscope, your surgeon will remove disc material from under the...
The cervical spine has eight cervical nerves, C1 through C8, that branch off of the spinal cord and exit through the neural foramen in the back of the spine. Each cervical nerve is named for the vertebra below it. For example, the nerve root that runs between the C5 and C6 is the C6...
the spinal canal through the intervertebral foramen (also called the nerve root canal) to branch out to your body. Both the spinal and nerve root canals are surrounded by bone and ligaments. Bony changes can narrow the canals and restrict the spinal cord or nerves (seeAnatomy of the Spine)...
The dominant motion in the lower cervical spine is flexion-extension, but the cervical spine's anatomy permits a fair amount of motion in all planes. In high-speed injuries, the head can act as a significant lever arm on the cervical spine and, depending on the mechanism, can create a ...
Lumbar Spine AnatomyThe spine, also called the back bone, plays a vital role in stability, smooth movement and protection of the delicate spinal cord. It is made up of bony segments called vertebra with fibrous tissue called intervertebral discs between them. The vertebra and discs form the ...
Anatomy of the spine The spine is made of 33 individual bony vertebrae 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. Strong bones and muscles, ...
