What is the correct order of the spine?
As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
What are the 5 vertebral column sections?
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.
From top to bottom, the vertebrae are: Cervical spine: 7 vertebrae (C1–C7) Thoracic spine: 12 vertebrae (T1–T12) Lumbar spine: 5 vertebrae (L1–L5)
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.
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.
What is the lowest part of the spine called?
The bottom of the spine is called the sacrum. It is made up of several vertebral bodies usually fused together as one. The remaining small bones or ossicles below the sacrum are also fused together and called the tailbone or coccyx.
Which is the correct order of regions of the vertebral column?
The spine is split into five regions: the cervical, thoracic, lumbar, sacral, and coccyx. The vertebrae of the sacrum and coccyx are fused, but those of the cervical, thoracic, and lumber regions are free to articulate.
Which portions of the spine are the most vulnerable to injury?
The Lumbar Spine
The lower part of your back is the most prone to injury, though they are often less severe injuries than when the cervical spine is involved. The lower back is composed of bones, muscles, and tissues that begin at the cervical spine and stretch down to your pelvic bone.
