Question

Synovial fluid is present in:
A. Spinal cavity
B. Cranial cavity
C. Freely movable joint
D. Fixed joint

Answer 1

Hint: Synovial fluid is present in the knee where it provides the cushioning effect to the knee joint. The knee joint is an example of the joint which can move freely. It allows the movement in one or more directions.

Complete answer:
To solve the given question, we must first know about the synovial fluid and the types of joints.
Freely movable joints are those joints which can move about in one or in more than one direction. Synovial joint is one such joint. The bones of this joint are enclosed inside a synovial membrane. There is a synovial cavity present inside. The cavity contains synovial fluid. This fluid is very important as it acts as a lubricant. It also provides the bones with the necessary nutrients and makes movement possible in more than one direction. At times it might happen that we might fall or there might be a jerk in these joints. Then it also acts as a shock absorber.
The different types of synovial joints are:
> Ball and socket joint
> Hinge Joint
> Gliding joint
> Pivot joint
> Saddle joint

Therefore, the correct answer to this question is that Synovial fluid is present in the freely movable joints.

Note:
Most of the joints present inside our body are synovial joints. They are located at those parts of the body where movement is required. It is also known as diarthrosis and always has a synovial capsule surrounding it.
