The spinal cord (and brain) are protected by three layers of tissue or membranes called meninges, that surround the canal . The dura mater is the outermost layer, and it forms a tough protective coating. Between the dura mater and the surrounding bone of the vertebrae is a space called the epidural space.
What surrounds the spinal cord?
Cerebrospinal fluid (CSF) surrounds the spinal cord, which is also shielded by three protective layers called the meninges (dura, arachnoid and pia mater). The spinal cord lies inside the spinal column, which is made up of 33 bones called vertebrae.
What is the spine area called?
The spine itself has three main segments: the cervical spine, the thoracic spine, and the lumbar spine. The cervical is the upper part of the spine, made up of seven vertebrae (bones). The thoracic is the center portion of the spine, consisting of 12 vertebrae. The lower portion of the spine is called the lumbar spine.
What are the sections of the spinal cord called?
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 are the levels of the spine?
There are four sections of the spinal cord: cervical, thoracic, lumbar and sacral. Each section of the spine protects different groups of nerves that control the body.
Can spinal problems cause heart problems?
Patients with SCI have a higher risk of cardiovascular complications and long-term effects as well as thromboembolism and autonomic dysreflexia. The recommended evaluation of cardiovascular dysfunction includes physiological, biochemical and pharmacological tests.
What are the three areas of the spine?
The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.
What is the structure of the spinal cord?
The spinal cord is a cylindrical structure of nervous tissue composed of white and gray matter, is uniformly organized and is divided into four regions: cervical (C), thoracic (T), lumbar (L) and sacral (S), (Figure 3.1), each of which is comprised of several segments.
Is spinal cord injury a disability?
Anyone with a spinal cord injury can file a claim for Social Security disability benefits as long as the injury has lasted at least three months and is expected to make it impossible for you to work for at least 12 months.
