What is sprain

Options

A. Overstretching of ligament
B. Overstretching of tendon
C. Both A and B
D. Dislodging of bone.

Answer

### Step-by-Step Solution:

1. **Definition of Sprain**: A sprain is an injury that occurs when ligaments, which are the fibrous tissues connecting bones to other bones, are overstretched or torn.

2. **Understanding Ligaments and Tendons**:
- **Ligaments**: These are fibrous tissues that connect one bone to another, providing stability to joints.
- **Tendons**: These are fibrous tissues that connect muscles to bones, allowing for movement.

3. **Cause of Sprain**: A sprain typically occurs due to the overstretching of ligaments. This can happen during activities that involve sudden twists or impacts that force the joint beyond its normal range of motion.

4. **Symptoms of Sprain**: The primary symptom of a sprain is pain in the affected area, along with possible swelling and limited mobility.

5. **Clarification on Misconceptions**: It is important to note that a sprain is not associated with the dislodging of bones; it specifically pertains to the overstretching or tearing of ligaments.

6. **Conclusion**: The correct understanding of a sprain is that it involves the overstretching of ligaments (and can also involve tendons), but it does not involve dislodging of bones.
