What are the 5 regions of the vertebral column from superior to inferior?

From superior to inferior, these are:

• Cervical – 7 vertebrae (C1 = highest; C7 = lowest)
• Thoracic – 12 vertebrae (T1 = highest; T12 = lowest)
• Lumbar – 5 vertebrae (L1 = highest; L5 = lowest)
• Sacral – 5 fused vertebrae (S1 = highest; S5 = lowest)
• Coccygeal – 3-4 fused vertebrae (Co1 = highest; Co3 = lowest)

What are the 5 regions of the spinal nerves?

In humans there are 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each pair connects the spinal cord with a specific region of the body. Near the spinal cord each spinal nerve branches into two roots.

How do you remember the 5 regions of the vertebral column?

You can use a meal-related mnemonic to remember them – imagine a crunchy breakfast at 7 am (7 cervical vertebrae), a tasty lunch at 12 noon (12 thoracic vertebrae), and a light dinner at 5 pm (5 lumbar vertebrae).

What are the five divisions of the vertebral column?

The vertebral column is a combination of several bones stacked on top of each other in a vertical fashion. It is divided into five separate sections as noted above, each consisting of a different type of vertebra bone, called the cervical vertebrae, thoracic vertebrae, lumbar vertebrae, a sacrum, and a coccyx.

What bone is the most inferior part of the vertebral column?

The coccyx, or tailbone, is both the smallest and the most inferior bone in the spinal column. It is a vestige of the caudal vertebrae found in the tails of most mammals.

What are the three regions of the vertebrae?

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).

What are four functions of the vertebral column?

The vertebral column has four main functions: Protection – encloses and protects the spinal cord within the spinal canal. Support – carries the weight of the body above the pelvis. Axis – forms the central axis of the body.
