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 Areolar tissue break

Answer
- Soln:
Answer is (c) Ligament break
Explanation:
Dislocation of bones occurs when joints held by ligaments get separated. Tendons joins skeletal muscle and they cause inflammation upon break.
Break of skeletal muscle cannot be the reason of bone dislocation as bones are joined by ligaments.
Areolar tissues are found around muscles, nerves and blood vessels hence they are not connected with bone dislocation.
