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 the correct option:

1. The radius and ulna are the two long bones in the hand.
2. An annular ligament or orbicular ligament is a strong band of fibers present on the head of the radius that retains it in contact with the radial notch of the ulna.
3. The person must have broken the ligament which dislocated these long bones leading to a fracture that helps to hold structures together
4. Maintains stability in the body
5. Joints that link the ends of the bones.

Explanation of the incorrect options:

Option A:

1. A tendon is a rope-like thread of robust, elastic tissue.
2. Tendon tissue connects our bones and muscles.
3. Tendons provide limb movement.
4. By absorbing some of the impact our muscles experience when we run, jump, or perform other activities, they also assist in preventing muscle injury.
5. Tendons have a very small chance of snapping or rupturing.

Option B:

1. Our skeletal muscles, which are connected to our bones and enable a variety of motions and actions, are these muscles.
2. Since skeletal muscles are voluntary, we have control over when and how they contract.
3. Muscle aches, stiffness, weakness, edema, and spasms can be brought on by strains.
4. The break of skeletal muscles cannot be responsible for the dislocation of bones as bones are joined by ligaments.

Option D:

1. The type of tissue that covers and connects the body's numerous organs is called areolar connective tissue.
2. Two of the most important tasks of this kind of tissue are to supply nutrients to the cells and serve as a cushion to shield the organs from various external stressors.
3. Areolar tissues are not concerned with bones because they surround blood arteries, muscles, and nerves.

Final answer: A person met with an accident in which two long bones of the hand were dislocated and the reason is because of a ligament break.
