FAQ’s – Vertebrae
What is the Difference Between the Spinal Cord and the Vertebrae?
The spinal cord is a band of nerves, tissues and cells. The vertebral column, a protective layer of the bone, wraps and protects the spinal cord. The bones in the vertebral column are referred to as vertebrae.
What are the Main Parts of the Spinal Cord?
There are 3 primary parts of the spinal cord – Cervical, Thoracic and the Lumbar region.
What is the Anatomy of a Typical Vertebra?
A typical vertebra is made up of the vertebral body that has a large anterior centrum and a posterior neural arch. The vertebral arch is composed of pedicles and laminae. There are seven processes arising from the vertebra.
What are the Unique Features of Sacral Vertebrae?
The sacral vertebrae are five in number and fuse into one large triangular bone in humans between the age of 18 to 30. They are situated at the base of the vertebral column.
What are the Unique Features of Lumbar Vertebrae?
The lumbar vertebrae are the largest bones of the vertebral column. The vertebral body of the lumbar vertebra is kidney shaped.
What are the 26 Bones of the Vertebrae?
The 26 bones of the spine are called vertebrae. The first 5 bones of the spine are known as the cervical vertebrae, the next 12 bones are known as the thoracic vertebrae followed by 5 lumbar vertebrae and then one fused sacral and a coccyx at the last.
What are the Functions of the Vertebrae Bones?
The vertebrae provide structural support and protection to the spinal cord, forming the backbone of the vertebrate skeleton. Additionally, they enable flexibility and movement of the spine, allowing for various body motions.
What are the Three Features of a Typical Vertebra?
A typical vertebra consists of a body, a vertebral arch, and a spinous process. The vertebral arch has two transverse processes and a spinous process.
Vertebrae – Bones, Diagram and Features
Vertebrae are a collection of bones which are found in all vertebrate animals. We have intervertebral discs that connect the 33 different-sized bones that make up our spinal column. Lumbar (5), sacral (1-fused), coccygeal (1-fused), cervical (7), and thoracic (12) are the five regions that make up the spinal column.
These 33 bones make up the region where the human cranium ends, and the coccyx begins in this group. The vertebrae provide structural support and protection to the spinal cord and enable flexibility and movement of the spine, allowing for various body motions.
