Question: 155: Which of the following is present between the adjacent bones of the vertebral column?
(1) Areolar tissue
(2) Smooth muscle
(3) Intercalated discs
(4) Cartilage
Answer: Option (4)
Explanation:
The vertebral column is made up of a series of vertebrae arranged one above the other.
Between adjacent vertebrae, intervertebral discs are present.
These intervertebral discs are composed of fibrocartilage.
Cartilage provides flexibility to the vertebral column and acts as a shock absorber.
Areolar tissue is a loose connective tissue found beneath the skin and around organs.
Smooth muscle is found in walls of internal organs.
Intercalated discs are special junctions present between cardiac muscle cells.
Therefore, cartilage is present between the adjacent bones of the vertebral column.
