Question

In rabbit, end of a long bone is connected in another by
A) Tendon
B) Ligaments
C) Muscles
D) Cartilage

Answer 1

Hint: Ligaments are present at the bone joints where two or more bones meet each other. It is a type of fibrous connective tissue.

Complete Answer:
Option a: Tendons, also known as sinew works as a tough fibrous connective tissue that helps in connecting our muscles with the bones. This makes tendons capable of withstanding the extreme tension that the bones undergo during strained conditions. As it does not connect the end of a long bone with another, thus, it is the incorrect option.

Option b: A ligament or fibrous connective tissue gets its name from its role of connecting one bone to another. Alternatively, it is also called a fibrous ligament or articular ligament or true ligament. Therefore, this is the correct option.
The characteristics of ligaments are,
- They are a band of dense regular connective tissue
- They help by stabilizing the joint
- There are two types of ligaments - white and yellow ligament

Option c: This soft tissue present in most of the animals contain protein filaments made out from myosin or actin sliding one past another. This gives rise to the contraction that takes place in muscles thereby resulting in changing both the cell length and shape. As it does not connect the end of a long bone with another, thus, it is the incorrect option.

Option d: Cartilage forms an important structural component of the human body. Due to its soft and flexible nature, the cartilage functions as a connective tissue that occurs at the joints of two or more bones such as the ankles, elbows, or kidneys. As it does not connect the end of a long bone with another, thus, it is the incorrect option.

Thus, the correct option option b) ligaments.

Note: Ligaments are the strong connective tissues protecting our bones from the bending, twisting or tearing apart under inflamed conditions.
