Question

Synovial fluid is present in joint cavities of freely movable joints. Which of the following statements is true about this fluid? a) It contains enzymes only. b) It contains hydrochloric acid. c) It contains lactic acid. d) It contains hyaluronic acid.

Answer 1

Of the options provided, the correct answer is d) It contains hyaluronic acid. Synovial fluid lubricates the joint, enabling smooth and greater movement within synovial joints.

Step-by-step explanation:

Synovial fluid is present in joint cavities of freely movable joints, known as synovial joints. This fluid has several functions, most importantly to lubricate the joint, reducing friction between the bones, and allowing for greater movement. Contrary to containing enzymes only, hydrochloric acid, or lactic acid, synovial fluid primarily contains hyaluronic acid, which is responsible for its viscous properties and lubricating function.

Answer 2

it contains hyaluronic acid

Step-by-step explanation:

Synovial fluid is made of hyaluronic acid and lubricin, collagenases and proteinases, . The synovial joints are covered with a tough, smooth cartilage called articular cartilage which together with synovial fluid allow friction free movements. The synovial fluid lubricates the joints, absorbs shock and supplies nutrients and oxygen to the articular cartilage.
