  • Thoracic spine: 12 vertebrae (T1–T12)
  • Lumbar spine: 5 vertebrae (L1–L5)
  • Sacrum: 5 (fused) vertebrae (S1–S5)

What are the 5 sections of the vertebral column in order from top to bottom?

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.

What is the order of the spinal column?

The vertebrae are divided into three regions: cervical C1–C7 vertebrae, thoracic T1–T12 vertebrae, and lumbar L1–L5 vertebrae. The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves).

How is the spinal cord arranged?

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.

What are the names of the 26 vertebrae?

The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

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.

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.
