The spinal column, more commonly called the backbone, is made up primarily of vertebrae, discs, and the spinal cord. Acting as a communication conduit for the brain, signals are transmitted and received through the spinal cord.
Is vertebral column and backbone same?
Vertebral column, also called spinal column, spine, or backbone, in vertebrate animals, the flexible column extending from neck to tail, made of a series of bones, the vertebrae.
What are the 3 main parts of a vertebra?
Cervical, Thoracic and Lumbar Spine
Each vertebra is made up of the vertebral body in the front, the facet joints in the back and the pedicles, which connect the vertebral body to the facet joints.
What are the three major types of vertebrae?

How many types of vertebral columns are there?
The spine is split into five regions: the cervical, thoracic, lumbar, sacral, and coccyx. The vertebrae of the sacrum and coccyx are fused, but those of the cervical, thoracic, and lumber regions are free to articulate.
What are the 4 types of vertebrae?
There are 33 vertebrae in the human spine that are split into four regions that correspond to the curvature of the spine; the cervical, thoracic, lumbar, sacrum, and coccyx.
Which vertebrae is most important?
Lumbar Spine: In your low back, you have 5 vertebrae that are labeled L1 to L5 (the ‘L’ means lumbar). Some people have 6 lumbar vertebrae. These vertebrae are your largest and strongest vertebrae, responsible for carrying a lot of your body’s weight.

| Notochord | Nerve cord |
|---|---|
| Notochord occurs in chordates. | Nerve cord occurs in both invertebrates and vertebrates. |
Is the spinal cord inside the backbone?
The spinal cord lies inside the spinal column, which is made up of 33 bones called vertebrae. Five vertebrae are fused together to form the sacrum (part of the pelvis), and four small vertebrae are fused together to form the coccyx (tailbone).
What is the function of spinal cord?
The spinal cord is a complex organization of nerve cells responsible for movement and sensation. It carries signals between the brain and the rest of the body.
What are the 5 areas of the spine?
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 many vertebral column are there?
Vertebrae. 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.
Where is vertebral column located?
The vertebral column, also known as the spinal column, is the central axis of the skeleton in all vertebrates. The vertebral column provides attachments to muscles, supports the trunk, protects the spinal cord and nerve roots and serves as a site for haemopoiesis.
What are the names of back problems?

…
Degenerative spine and disc conditions:
- Arthritis.
- Degenerative disc disease.
- Herniated disc.
- Spinal stenosis.
- Spondylosis.
What absorbs shock in the spine?
The intervertebral discs are soft structures which act as shock absorbers between each of the vertebrae (bones) in the spine. A single disc sits between each vertebra. Each intervertebral disc has a strong outer ring of fibres (‘annulus’), and a soft, jelly-like centre (nucleus).
What are the 26 vertebrae?
The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body — 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx.
What is the main function of the vertebral body?
The vertebrae protect and support the spinal cord. They also bear the majority of the weight put upon your spine. The body of each vertebra is the large, round portion of bone. The body of each vertebra is attached to a bony ring.
Which vertebra has the Odontoid process?
The odontoid process (also dens or odontoid peg) is a protuberance (process or projection) of the Axis (second cervical vertebra). It exhibits a slight constriction or neck, where it joins the main body of the vertebra.
What is the function of a vertebra?
Each vertebra is composed of several parts that act as a whole to surround and protect the spinal cord and nerves, provide structure to the body and enable fluid movement in many planes.
