Exploring The Wonders Of Vertebrae Anatomy
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:
- Cervical region
- Thoracic region
- Lumbar region
General characteristics of the Vertebrae Anatomy
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.

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.
