Question

Which of the following is not a characteristic of the synovial fluid? 

a. lubrication 

b. shock absorption 

c. regulation of water balance in the joint 

d. protection of articular cartilage 

Step-by-Step Solution

Answer

The correct answer is (c) regulation of water balance in the joint  

Regulation of water balance in the joint is not a characteristic of the synovial fluid.  

Step 1. Introduction

Synovial fluid, also known as joint fluid, is a thick liquid located between your joints. The fluid cushions the ends of bones and reduces friction when you move your joints.

Step 2. Explanation for the correct answer

c. regulation of water balance in the joint 

The function of synovial fluid are :

• it keeps the bones slightly apart, protecting their cartilage coverings from wear and tear.
• it absorbs shocks, again protecting the cartilage.
• it lubricates the joint, helping it to work freely and easily.

Not regulation of water balance in the joint. So, this option is correct.

Step 3. Explanation for the incorrect answer

a. lubrication 

• Synovial fluid is the thick liquid that lubricates your joints and keeps them moving smoothly. 

b. shock absorption 

• Synovial fluid absorbs shocks, again protecting the cartilage. 

d. protection of articular cartilage 

• Synovial fluid it keeps the bones slightly apart, protecting their cartilage coverings from wear and tear.
