What are the 3 parts of your vertebral column and how many each?

Vertebral Column and Spinal Cord It is organized into 31 segments: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal; each segment innervates a dermatome via a spinal nerve.

What are all the sections of the vertebral column?

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.

How are the vertebrae numbered?

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. The vertebrae in each region have unique features that help them perform their main functions.

What are the numbers of the spine?

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)
• Sacrum: 5 (fused) vertebrae (S1–S5)
• Coccyx: 4 (3–5) (fused) vertebrae (Tailbone)

How many vertebrae are in the vertebral column?

The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.

How are the vertebrae numbered and identified?

Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. 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.

How are spinal discs numbered?

The bone numbering starts at the top, near the skull, with C1 and then each bone going down is given a higher number with the last bone in the neck called C7. Between those bones are discs, each given two numbers that coorespond to the bone above and below the disc. The disc located between C4 and C5 is called C4-C5.
