Question

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

1. lubrication
2. shock absorption
3. regulation of water balance in the joint
4. protection of articular cartilage

Short answer

The correct answer is option (c) .

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

Step-by-step solution

Synovial fluid

• Synovial fluid may also be referred to as joint fluid.
• The fluid between your joints is called synovial fluid.
• A series of tests, termed "synovial fluid analysis", are performed to look for joint diseases.

 Step: 1 Explanation for correct answer

Lubrication, shock absorption, and articular cartilage protection are all duties of the synovial membrane. Thus, the option c is correct.

 Step: 2 Explanation for incorrect answer

The main function of synovial fluid is to lessen friction between the articular cartilages of synovial joints during movement, hence it does not regulate the water balance in the joint. Hence, option a, b and d is wrong too.
