Spine: conas atá sé déanta suas?

The spine, also called the spine, is a bone structure located between the head and the pelvis.

Anatomy of the spine

Structure of the spine

The spine is made up of an average of 33 bones, called vertebrae. These bones are linked together to form an axis, which has a double S shape. From the upper part to the lower part, these 33 vertebrae are defined according to their location (2):

  • 7 cervical vertebrae
  • 12 thoracic vertebrae
  • 5 lumbar vertebrae
  • 5 sacral vertebrae fused together to form the sacrum
  • 4 coccygeal vertebrae fused together to form the coccyx

Being flexible and mobile, the first 24 vertebrae are considered the true vertebrae while the sacrum and coccyx, remaining fixed, are considered the false vertebrae.

Structure of the vertebrae

Each vertebra has the same basic constitution (1) (2).

  • The body, the ventral part of the vertebra, is large and solid. She carries the weight of the skeletal axis
  • Tá an áirse veirteabrach, an chuid droma den veirteabra, timpeall ar na foraoisí veirteabracha.
  • Is é an foramen veirteabrach an chuid lárnach den veirteabra atá cuasaithe amach. Is éard atá i gcruach na veirteabraí agus na foramina an chanáil veirteabrach, a thrasnaíonn corda an dromlaigh.

Musculature

Tá an spine clúdaithe ag na matáin droma.

Ról soghluaisteachta agus staidiúir. The spine helps to preserve the posture of the trunk and thus maintain the standing position. The structure of the spine allows many movements such as torsion movements of the trunk, bending of the trunk or even traction.

Spine problem and back pain

Back pain is defined as localized pain that begins most often in the spine and generally affects the muscle groups around it. According to their origin Three main forms are distinguished: neck pain, an dorsalgies agus pian ar ais íseal. sciatic, characterized by pain starting in the lower back and extending into the leg, are also common and are due to compression of the sciatic nerve. Different paiteolaíochtaí can be at the origin of these pains. (3)

  • Degenerative pathologies. Different pathologies can lead to the progressive degradation of cellular elements. Osteoarthritis is characterized by the wear and tear of the cartilage protecting the bones of the joints. (4) The herniated disc corresponds to the expulsion behind the nucleus of the intervertebral disc, by wear of the latter. This can result in compression of the spinal cord or sciatic nerve.
  • Deformation of the spine. Different deformation of the column may appear. Scoliosis is a lateral displacement of the column5. Kyphosis develops with an excessive curvature of the back at shoulder height while lordosis is associated with an accentuated arch in the lower back. (5)
  • Lumbago and stiff neck. These pathologies are due to deformations or tears in the ligaments or muscles, located respectively in the lumbar region or in the cervical region.

Scéal

Foilsithe san iris eolaíochta Stem Cell, d’éirigh le taighdeoirí ó aonad Inserm gaschealla adipose a athrú go cealla ar féidir leo dioscaí intervertebral a athsholáthar. Tá sé mar aidhm ag an obair seo na dioscaí caite intervertebral caite a athnuachan, ag cruthú cuid den phian sa chúl níos ísle. (6)
