Question

A person met with an accident in which two long bones of hand were dislocated. Which among the following may be the possible reason?

• A. Tendon break
• B. Break of skeletal muscle
• C. Ligament break
• D. Areolar tissue break

Answer 1

The correct option is C

Ligament break

The correct option is C

Explanation of correct option:

1. The hand consists of two long bones that are radius and ulna.
2. The person must have broken the ligament break which dislocated these long bones leading to fracture.
3. The function of ligament: It connects the bones to joints.
4. It maintains the stability of the body.

Explanation of incorrect options:

Option A

Tendons join skeletal muscles to the bones and tendon break causes inflammation. So that tendon is an incorrect option.

Option B

The break of skeletal muscle cannot be responsible for the dislocation of bones as the bones are joined by ligaments.

Option D

Areolar tissues are found around the muscles, nerves, and blood vessels so they are not responsible for bone dislocation.

Final Answer: Ligament break led to the dislocation of the two bones.
