Smooth muscle

Verified By Collegedunia

The Correct Option is B

Solution and Explanation

The question asks us to identify the structure that is present between the adjacent bones of the vertebral column. To solve this, we need to understand the anatomy of the vertebral column.

The vertebral column is made up of individual vertebrae, and between each pair of adjacent vertebrae is an intervertebral disc. These discs are crucial as they allow for movement between the vertebrae and act as shock absorbers.

The intervertebral discs are composed of cartilage, specifically fibrocartilage, which provides strength and flexibility. Thus, the correct answer to the question is Cartilage.

In contrast, let's briefly examine why the other options are incorrect:

Intercalated discs are specialized structures found in cardiac muscle cells and not related to the vertebral column.
Areolar tissue is a connective tissue that primarily holds organs in place and is not specifically found between bones of the vertebral column.
Smooth muscle is found in walls of hollow organs and blood vessels but not between vertebrae.

Therefore, the presence of cartilage between the vertebrae is essential for the vertebral column's structure and function.

Locomotion and Movement

Locomotion

The movement of a creature from one place to another is known as locomotion. During the process, there is the action of appendages such as wings, limbs, and flagella. In some animals, like fish, whales, and sharks, locomotion upshots from a wave-like series of muscle contractions. Locomotion helps an organism in finding their food, avoid harsh weather conditions, escape from their predators, etc.

Some examples of locomotion are walking, running, swimming, etc. Movement, on the other hand, refers to any type of motion that need not be localized.

Movement

Movement is generally described as a state of changing the position from rest to motion or vice-versa. Movement can be both voluntary movement and involuntary movement. Movement helps an organism perform essential functions, such as pumping blood to the different parts of the body, etc.
