What is vertebral column and its function?
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 5 vertebral column?
Vertebrae. As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
What is the difference between vertebral column and spinal cord?
The vertebral column is a segmented bony structure supporting the head/torso and thorax. The spinal cord runs in the vertebral column….Difference Between Backbone and Spinal cord.
| Backbone | Spinal cord |
|---|---|
| Holds the spinal cord | Found inside the backbone |
| Length in humans | |
| Longer than spinal cord | Shorter than backbone |
| Function |
What is a vertebral body?
The vertebral body is the main portion of the vertebra. It bears about 80 percent of the load while standing and provides an attachment for the discs between the vertebrae. The front or anterior section of the vertebral body protects the spinal cord and nerve roots.
What is vertebral column Class 9?
It is also known as the vertebral column. The vertebral column is a part of the axial skeleton, which comprises the skull, ribs and sternum other than the vertebral column. Each vertebra has a central hollow portion, which forms the neural canal through which the spinal cord passes. The spine protects the spinal cord.
What are the 3 sections of the spine?
The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.
Where is C1 and C2 on the spine?
cervical spine
The C1 and C2 vertebrae are the first two vertebrae at the top of the cervical spine. Together they form the atlantoaxial joint, which is a pivot joint. The C1 sits atop and rotates around C2 below. More of the head’s rotational range of motion comes from C1-C2 than any other cervical joint.
Where is the vertebral column?
The bones, muscles, tendons, and other tissues that reach from the base of the skull to the tailbone. The vertebral column encloses the spinal cord and the fluid surrounding the spinal cord. Also called backbone, spinal column, and spine.
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. 2).
What is vertebral column made of?
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 is vertebral column Class 10?
Vertebrae in Human Body: The axial skeleton comprises the vertebral column, often regarded as the backbone skeleton or spine. The spinal canal (backbone skeleton), a cavity that encircles and protects the spinal cord, is housed within the vertebral column. A vertebral column is found in about 50,000 animal species.
What does a vertebral column look like?
The vertebral column is characterized by a variable number of curves. In quadrupeds the column is curved in a single arc (the highest portion occurring at the middle of the back), which functions somewhat like a bow spring in locomotion.
What are the 5 sections of the vertebral column?
Cervical (top)
What are 5 major regions of the vertebral column?
5 Main Regions of the Vertebral Column 7 cervical vertebrae make up the neck, and they are abbreviated C1-C7. 12 thoracic vertebrae are next, which are abbreviated as T1-T12. 5 lumbar vertebrae are inferior (below) the thoracic vertebrae, abbreviated as L1-L5. 1 sacrum, which consists of fused sacral vertebrae S1-S5.
What are the five divisions of the vertebral column?
List the divisions of the spinal column and specify the number of bones contained in each division. Also, indicate the importance of each division in the total construction of the body. The five divisions of the spine are cervical (neck), thoracic (chest), lumbar (waist), sacral (lower back), and coccygeal (tailbone).
