The vertebrae anatomy is one of the greatest bone structures of our body. The vertebrae serve many functions and purposes. It is given a high regard when it comes to giving the body form, support, and movement. The vertebrae help an individual to sit and stand upright, walk, run, jump, dance, and do many other activities. The importance of the vertebrae should never be underestimated.

 Overview of the Vertebrae Anatomy

The whole adult spinal column is composed of 33 vertebral bones. These bones are subdivided into 5 categories which are:

General characteristics of the Vertebrae Anatomy

The cervical region is composed of 7 vertebral bones which are named as C1-C7. The C1 is called the atlas because it holds the head at its place while the C2 is called the axis because it enables the head to rotate.

The thoracic region is composed of 12 vertebral bones which are named as T1-T12. Attached to these vertebrae are 12 pairs of ribs. The thoracic region along with the rib cage protects the vital organs such as the lungs and heart.

The lumbar region is composed of 5 vertebral bones which are named as L1-L5. The lumbar bones are the biggest bones of the spinal column. It is designed this way because the lumbar bones are the main weight-bearing structure of the body. The L5 connects the spinal column to the pelvis.

The sacrum is composed of 5 bones and is part of the pelvic area. The whole sacral region is big and triangular in shape. At the age 16-18, the 5 bones will slowly fuse until it is completely unified at the age of 34.

The coccyx, also known as the tailbone, is composed of 4 vertebral bones. The tailbone is very important because it is the area where various muscles, ligaments, and tendons are attached. The coccyx, as part of the vertebrae anatomy, functions as a weight-bearing structure during a sitting.

Basic Parts of a Vertebra

Each vertebra is unique in shape, size, and form. Depending upon its location, the vertebra is especially designed to perform a specific function. The vertebrae anatomy is composed of a body located anteriorly. At the posterior part of a vertebra lies a neural arch that forms a ring. The ring creates a canal for the spinal cord. Another part of the vertebra is the spinous process which is the bony prominence that you feel when you run your finger down someone’s back. This is also the area where muscles are attached. Between each vertebra are the intervertebral discs that act as a shock absorber of the spinal column.

Summary of the Vertebral Anatomy

The vertebrae anatomy is truly an amazing structure of the body’s skeletal system. It plays a role in coordinating movements, giving the body its form and shape, protecting vital organs, and housing the spinal cord.

This article basically addresses the fundamental points that you need to know about the spinal column. The vertebrae anatomy is very crucial for the continued existence of an individual.
