Question

A synovial cavity is found in ________ joint.

Answer 1

Hint: Synovial fluid usually occurs in the knee where it provides the cushioning effect to the knee joint. The knee joint is a perfect 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 have knowledge about the synovial fluid and the types of joints.
Freely movable joints are defined as those joints which can move about in one or in more than one direction.
Synovial joint is an example of one such joint. The bones of this joint are covered inside a synovial membrane. There is a synovial cavity that remains inside. The cavity is composed of synovial fluid. This fluid is very crucial as it acts as a lubricant. It also gives the bones necessary nutrients and allows movement possible in more than one direction. At times it could have happened that we might fall or there might be a jerk in these joints. Then it also functions as a shock absorber. some different types of synovial joints are:
1.Ball and socket joint: It is present between the head of femur and clavicle.
2.Hinge joint: They are present in toes, fingers and ankle.
3.Gliding joint: It is present in wrists and also in the ankle.
4.Pivot joint: They are present in the atlas and axis.
5.Saddle joint : It is present between metatarsals.

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